The simulator contains a low power (<3mW) 650nm visible (red) laser. The muzzle insert contains a low power (<3mW) 780nm invisible (infrared) laser.

• Never look directly into the beam of any laser — risk of blindness.
• The SGA laser fires a short pulse (~40ms) when the trigger is pressed. The UGA muzzle insert fires a shorter pulse (~30ms), controlled by the trigger box.
• You will not see the infrared beam — it is invisible to the human eye but can still cause damage.
• Never point the SGA or UGA muzzle insert at another person.
• The simulator has a 12-second safety timeout — if the laser is on and you don't shoot, it turns off automatically.

Battery types used in DryFire gun assemblies:

• SGA (current): 1 × CR2032 coin cell (standard disposable — not rechargeable)
• UGA (legacy): 3 × LR44 button cells (not rechargeable)

• Keep batteries out of reach of small children — if swallowed, consult a physician immediately.
• Never charge, disassemble, or short batteries.
• Never expose batteries to direct heat or dispose by incineration.
• If batteries leak, remove them, clean the compartment with a damp cloth, and allow to dry before replacing.
• Always insert batteries with correct polarity (positive/negative).
• Remove batteries if storing the equipment for a long time.

The DryFire power supply accepts 110–250V 50Hz/60Hz input and produces 5V regulated output with a positive center terminal.

• Do not handle the power supply with wet hands.
• Never attempt to open the power supply — high voltage inside.
• Do not use any other power supply with DryFire — this voids the warranty and may cause fire or damage.
• If the case is damaged from being dropped, dispose of the unit and order a replacement.

DryFire can simulate tower shots directly above your head. Before selecting overhead targets, make sure your room has enough space overhead for you to swing your barrel vertically without hitting lights or the ceiling.

Do not select tower targets if your room is too low — otherwise you risk breaking lights and ceiling fixtures.

• Do not disassemble any part of the equipment.
• Do not allow children to handle the equipment.
• Protect equipment from high temperatures, direct sunlight, humidity, and rain.
• Do not move equipment suddenly from cold to hot environments — condensation can damage circuitry.
• Store between 10°–60°C and 10–80% humidity.
• If equipment has contacted liquids or been physically damaged, remove batteries, disconnect all cables, and have it examined before use.

DryFire requires a Windows PC with a spare USB port. Macs are not supported.

Supported Windows versions: XP (SP3), Vista (32/64-bit), Windows 7 (32/64-bit), Windows 8 (32/64-bit), Windows 10 (32/64-bit), Windows 11.

You need a fairly flat wall and room to stand behind the simulator:

• Minimum: 8 × 8 ft space with an 8 ft wall (single head, single shooter).
• Trap / Sporting Clays: A 10 ft wide wall works well.
• Skeet: An 18 ft wall is best; a 12 ft wall works with special layouts.
• Doubles / Team shooting (dual head): 14–18 ft width recommended.

The wall should not be extremely rough (e.g. bare stone or brickwork) or colored dark green. You need a clear, visible red laser spot on the wall. No direct sunlight or artificial light should fall on the shooting wall or into the simulator's camera.

Position the simulator approximately 48 inches from the wall, near the center of the wall. Shooters stand approximately 8 ft from the wall.

The simulator base is 6″ × 6″ × 4.25″ (152mm × 152mm × 63.5mm). It has a standard photographic tripod bushing built into the base and can also be ceiling-mounted.

Each head contains a laser (A) for projecting targets and a camera (B) for detecting your shots. The simulator is available in single or double-head configurations.

Back panel connectors:

• A — Power socket (5V regulated, positive center terminal)
• B — Manual release (optional Wireless Release device)
• C — Microphone (active when Wireless Release is not connected; responds to "Pull" command)
• D — USB socket (connect to PC — do not connect until instructed)

The SGA is a laser device. When you press the trigger switch, it sends out a short (~40ms) pulse of low-power invisible infrared laser light that bounces off the wall/screen and is detected by the cameras in the simulator.

What's in the box

• SGA laser unit — clips under the barrel of your shotgun, close to the fore-end. Make sure the laser is pointing toward the muzzle.
• Magnetic Quick Mount Adapter — the SGA comes pre-attached to this adapter for easy magnetic mounting on 12 or 20-gauge shotguns.
• Wrap-around trigger switch — designed like a tie-wrap; goes around the trigger blade so the micro switch sits under your trigger finger. Connect the other end of the wire to the SGA.

Mounting options

• 12 or 20-gauge: Magnetic mounting via the Quick Mount Adapter — easiest option.
• .410 or BB gun: Use a barrel clamp (available upon request from DryFire USA).

Confirming it works

The red status LED will flash briefly each time the trigger switch is pressed (or released, if configured in Release to Fire mode). If the LED does not flash, replace the battery.

Battery

The SGA uses a single CR2032 coin cell battery (standard disposable — not rechargeable). To replace:

1. Remove the 4 screws from the bottom of the SGA box.
2. Remove the old battery and insert a new CR2032.
3. Replace the bottom cover and re-insert the 4 screws. Do not overtighten.

The UGA gun assembly includes three components that work together:

• Muzzle Laser Insert — Fits into your shotgun barrel, emits an infrared pulse (~30ms) when triggered.
• Trigger Box — Connects the trigger switch to the muzzle insert. Powered by 3 × LR44 button cell batteries (not rechargeable). Has a red LED that flashes when a shot is registered.
• Trigger Switch — Attaches to your trigger and sends the signal to fire the muzzle laser.

Check current mode

Press the trigger switch and watch the red status LED on the SGA. If it flashes when pressed → Press to Fire mode. If it flashes when released → Release to Fire mode.

Switch to Release to Fire mode

1. Remove the 4 screws from the bottom of the SGA box.
2. Locate the small shorting link inside (note: link color may vary).
3. Move the shorting link so it connects across the 2 pins.
4. Plug in your trigger switch and test: the red LED should now flash when you release the trigger switch.
5. Replace the bottom cover with the 4 screws. Do not overtighten.

Return to Press to Fire mode

1. Remove the 4 screws from the bottom of the SGA box.
2. Move the shorting link back so it no longer connects across the 2 pins.
3. Test: the red LED should now flash when you press the trigger switch.
4. Replace the bottom cover with the 4 screws. Do not overtighten.

Check current mode

Press the trigger switch and watch the red LED on the trigger box. If it flashes when pressed → pull (normal) mode. If it flashes when released → release trigger mode.

Switch to release trigger mode

Hold the trigger switch down for approximately 10 seconds until the LED turns on and stays on. Confirm: press switch (LED should NOT blink), release switch (LED should blink).

Return to pull (normal) mode

Remove batteries from the trigger box. With batteries out and trigger switch connected, hold the switch for 30 seconds. Re-insert the batteries.

No — but DryFire works best in subdued light. The camera uses infrared light, and direct sunlight also contains infrared, which can interfere with shot detection.

• Normal daylight is fine as long as sunlight is not directly hitting the shooting wall.
• Close curtains or blinds to block direct sun if needed.
• Fluorescent and LED lights produce the least infrared interference.
• Do not position a light directly in front of the DryFire unit.

DryFire has an auto-exposure function and will notify you if stray bright light is causing problems.

Yes — software updates are free and can be downloaded from the DryFire website at any time. This includes firmware updates for the simulator itself.

If you cannot download the files yourself, a flash drive with the latest update can be purchased for $10.00 from the DryFire store.

Start DryFire by double-clicking the DryFire V4 shortcut on your Windows desktop, or via Start → Programs → DryFire → DryFire V4.

On first install, shooter passwords are disabled. Default passwords if you enable them:

• Administrator password: dryfire
• Shooter 1 password: red

Each time you start DryFire (or insert/move the muzzle insert), you must complete the Muzzle Alignment process before shooting. Press F1 at any time to open Help.

Each time you place the muzzle insert into your barrel it will project the laser in a slightly different direction. DryFire must know exactly where the laser is pointing to determine where you aimed. Calibrate every time you start DryFire or if the insert may have moved.

Alignment steps

1. Click the Align button on the DryFire toolbar (right of shooter/gun name).
2. DryFire projects a static laser dot on the wall directly in front of your shooter location.
3. Take a shot at the laser dot — use your bead to cover the dot both vertically and horizontally. Do not add lead. Do not float the target. Only your last shot is registered.
4. Click OK if confident, or Check to verify alignment.
5. If checking: shoot at the dot again. Your shot should appear at the center of the displayed target. Click OK to continue.

Layouts define which targets DryFire presents. Go to File → Layouts to open the Layouts dialog. The left column lists all available layouts organized by type (click green headings to expand/collapse).

Use the filter box to search layouts by name. Click a layout to preview it, then click OK to open it.

DryFire V4 includes: ATA, ABT, DTL, Olympic Trap; English, American, and Olympic Skeet; Universal Trench; and several Sporting layouts.

Once you click Start, a green status circle and a "ping" sound indicate DryFire is ready. Release a target by:

• Calling "Pull" loudly (microphone on simulator)
• Pressing the foot release switch
• Pressing the SPACE BAR on your PC

The status circle changes to red (preparing), then yellow (target released, laser dot on wall). If no shot is detected, DryFire counts it as "no bird" and repeats the target.

Automatic target release

Enable via Setup → Automatic target release or by clicking the status circle. Set a release interval — the circle fills red as time passes, then auto-releases. Press Ctrl+Y to toggle on/off quickly.

After each shot, DryFire displays a zoomed view showing the shot cloud (brown circle of pellets) relative to the clay (orange). A dashed orange line shows the clay's trajectory; a dashed yellow line shows the shot path.

Result types:

• HIT! — Clay broken.
• MISS! — Shot cloud did not reach the clay.
• NOT BROKEN! — Clay was within the shot cloud but pellets lacked enough energy to break it at that distance. Shoot earlier (closer) or use a tighter choke.
• WRONG CLAY! — For doubles where shot order matters, you aimed at the wrong clay.

Details shown: Pointing error distance, Above/Below, Ahead/Behind, Left/Right, distance from you to clay, time since clay was released.

Reduce clay speed to practice mounting, swinging, and acquiring targets at a manageable pace:

1. Go to Setup → System Configuration.
2. Find Clay speed in the PC Settings section.
3. Set to 50% for half speed, or any value down to 0. Normal speed = 100%.
4. Click OK. Targets will now move at the reduced speed.

Olympic shooters sometimes practice at 75% speed to build extra reaction time. Gradually increase speed back to 100% as your confidence builds.

Stop motion projects a static laser showing exactly where the clay would be at any point in its flight, along with the correct aim point.

How to use stop motion

1. Press F8 to show the Sidebar, then click Target tools.
2. Drag the Target position slider (left = launch, right = landing) — DryFire shows the clay position on the wall in real time.
3. Alternatively, type a specific Time or Distance from trap value.
4. Tick Show aim point to project where you should point your gun to hit the clay at that position.
5. Tick Switch shot order to change which barrel is used.
6. Click End stop motion when done.

DryFire maintains your score on the toolbar and records shot results in the Score card section of the sidebar (press F8 to show). Click Reset on the toolbar to zero the score.

Score card icons in the sidebar show: Hit with both shots, Shot 1 miss / Shot 2 hit, Shot 1 hit / Shot 2 miss, or Miss with both shots. You can save the score card as a PDF or print it using the icons in the Score card heading.

The pattern board confirms your DryFire gun shoots like your real gun, accounting for POI and choke. Access it via Setup → Pattern board or press F7.

1. Use the Distance slider to set how far you're standing from the board.
2. Select the appropriate Shooter, Gun, and Barrel on the toolbar.
3. Click Fire — DryFire shows where the shot cloud would appear for a perfect aim.
4. To take a real shot, click Show Laser and aim directly at the static dot.
5. Click Clear to reset, and Finish when done.

You can also use the pattern board to calculate equivalent POI at different distances — useful when you need to pattern at a shorter range than your gun's defined POI distance.

Hold points are positions in a clay's flight where you position your gun before calling "Pull." DryFire maintains shooter-specific hold points for each target in each layout.

Setting a hold point

1. Press F8 to show the Sidebar → click Target tools.
2. Select the target and shooter on the toolbar.
3. Use the slider or type a time/distance to show the clay at the desired wall position.
4. Click Set to save that position as your hold point.

Once set, press F2 or go to View → Clay positions on wall to display your hold point along with launch, intermediate, and landing positions.

Use these shortcuts to navigate the DryFire 3D view:

• Ctrl+A — View from above
• Ctrl+F — View from front of layout
• Ctrl+S — View from selected stand
• Ctrl+C — Clay's eye view (animation from clay to stand)
• Ctrl+W — Walk the course (preview all targets; press again to stop)
• Mouse wheel — move forward/backward
• Cursor keys or click-drag — pan the view
• SHIFT + drag — alternative pan directions
• F4 — Toggle layout information box
• F8 — Toggle sidebar
• F9 — Toggle preview window

Trap layouts launch rising clays, so a gun that shoots high is typically used. Select Trap gun from the Shotgun list on the toolbar (default POI: 70:30, 0.2m high at 32m).

Open via File → Layouts and select a trap layout (e.g., Trap American Double or DTL (Double Rising)). Select a specific target from the Target list, or select Round to practice a full round of five simultaneous doubles from each of the five stations.

The trap changes angle (within ATA limits) after each shot. If you do not fire, it counts as "no bird" and the same angle repeats.

You can shoot doubles with either a single or double head simulator. With a single head:

• DryFire shows one clay at a time.
• When you hit the first clay (or must move to the second), DryFire automatically switches to the second clay at whatever point it would have reached in its flight.
• For ATA Trap Doubles: the right bird is shown first for posts 1–3, left bird first for posts 4–5.
• Only one shot per clay in any order — hitting the same clay twice with your second shot does not count.

For skeet, use a gun that shoots 50:50 ("flat") — select Skeet gun from the Shotgun list. Open via File → Layouts → Skeet English (or American/Olympic).

The English Skeet layout requires the simulator to be inclined at 45° for targets from stands 1, 2, 6, and 7. DryFire will notify you. If you only shoot from stands 3, 4, and 5, you can leave the simulator horizontal (set Simulator Angle to 0 in System Configuration).

Skeet layouts work best in Move around the room mode with wide walls (~5m/5.5 yards). For narrower rooms, use Target comes to shooter mode. Stands 1, 6, 7, and 8 targets are always shown from Stand 4's room location in Move around the room mode.

DryFire V4 offers two room modes for most non-Sporting layouts:

Target comes to shooter (default)

All shots are taken from the same physical location. DryFire shows the clay's trajectory as it would appear from the correct stand on the range. Supported by all layouts.

Move around the room

Shooters stand at different physical locations depending on the station. DryFire projects clays through fixed anchor points (traps, houses, stakes) on the wall. Best used with a scenic wall canvas. Works best with wider walls.

Switch modes via the Configure room mode and anchor points button, or Setup → Room mode and Anchor points. The Room layout diagram in the sidebar shows the active mode, simulator location, room stands (red checked squares), and anchor points (blue triangles).

DryFire includes several Sporting Clays layouts and supports full FITASC simulation. You can practice crossers, walk-ups, driven, quartering, teal, tower, and rabbit targets.

Create your own Sporting or FITASC layouts using the Course Designer add-on (see Features & Add-ons section). Share your custom layouts at dryfire.com.

The Game add-on (requires Projection add-on) simulates flying birds, rabbits, and stationary targets. Game layouts included:

Ducks, Flocks, Mixed Hunting, Pheasants, Pigeons, Partridges, Plinking, Plinking Fast, Rabbits, Teals.

Targets appear as silhouettes against the projected background. You must allow for lead as with real clays. In flock targets, the bird you should aim at is shown in black; the rest appear in gray.

The Rifle & Pistol add-on supports short-range target practice and a hunting option. Setup is similar to a shotgun but different properties apply, including ballistic coefficient (from your ammunition manufacturer).

Access via File → Rifle and Pistol target…. Set target size, height, and distance. After alignment, a zoomed view is shown. The most recent shot appears in purple; previous shots in red.

Shot history can be reviewed, compared across sessions, printed, or saved as a PDF. For accuracy, stand the exact distance from the wall as shown in the dialog, and ensure shooter eye height is set correctly.

DryFire V4 starts with Shooter 1 and two guns (Skeet gun, Trap gun). Edit or create shooters via:

Edit existing shooter

1. Select the shooter on the toolbar and click Edit shooter.
2. Change name, eye height (height of shooter's eye from floor with gun mounted), ATA handicap yardage, and password.
3. Double-click a gun in the list to edit it, or click New gun to add one.

Create new shooter

1. Click New shooter on the toolbar.
2. Complete name, eye height, and password.
3. Click New gun to add at least one gun.

Accurate gun settings help DryFire correctly determine hits and misses. For each gun/barrel, configure:

• Point Of Impact (POI) — How high/flat the gun shoots at a defined distance. Express as distance above aim point or as a percentage/ratio.
• Choke — Type fitted to each barrel (tighter = more accurate required, more effective at range).
• Barrel length — Affects shot timing calculations.
• Cartridge — Muzzle velocity, shot size, weight of load, hardness (trap, tungsten, hevishot, etc.).

Edit via: select shooter → select gun → click Edit shotgun button on toolbar.

To share a gun so any shooter can use it, select "Any shooter can use this gun" from the Share option.

Passwords are disabled by default. Default passwords when enabled: Admin = dryfire, Shooter 1 = red.

Enable/disable passwords

1. Setup → System Configuration → Advanced button.
2. Tick/untick Enable shooter passwords.
3. Click OK.

When enabled: shooter's password (or admin password) is needed to edit shooter/gun settings. A "master" shooter can access system configuration and add shooters. Admin password is always needed to delete shooters.

Any shooter can change their own password if they know their current one. The admin password can reset any shooter's password.

Configure room dimensions for accurate target projection:

1. Setup → System Configuration → Simulator Settings section.
2. For sloped ceilings or side walls: click Advanced → Room settings section.

Room settings explained:

• Slope start height (h) — Height from floor where the wall begins to slope inward. Set to 0 if no slope.
• Slope length (i) — Length of slope from start height to ceiling. Enter as negative number if measuring horizontal distance instead.
• Left/Right side wall — Length of side wall usable for wide targets.
• Mount simulator upside down — Tick if mounted on the ceiling.

You can also set Latitude, Altitude, and Temperature of the simulated shooting range to affect clay and shot trajectories.

Double-click the word Metric or Imperial in DryFire's status bar (bottom of the screen) to toggle between measurement systems instantly — no dialog required.

You can also change this via Setup → System Configuration → Advanced → Locale settings → Use imperial measurements.

DryFire can announce scores and provide spoken instructions during a round. To enable:

1. Setup → System Configuration.
2. Find Speech in the Program Options section.
3. Set to Chatty for full announcements.
4. Click OK.

You'll hear a "ping" whenever DryFire is ready to release a target — so you don't need to watch the screen between shots. Shot sounds ("bang") play through your PC speakers.

The Projector option lets DryFire display a scenic background through a projector connected to a second display adapter on your PC.

1. Connect projector to your PC's second display adapter.
2. Press Win+P → select Extend.
3. In DryFire: View → Projector window (tick it) — image projects immediately.
4. Configure options via Setup → Projector options.

Options include: Show results as text, Show clay and shot positions, Color-coded shots, Use projected menu, choose laser vs. projected targets.

In trap shooting, you need to shoot before the target travels too far. DryFire's Target Options dialog lets you set a distance from the shooter at which a warning sound plays.

If you hear the sound, the target has gone too far. Use this as feedback to take the shot earlier. Combine with Stop motion to identify exactly where on the wall you want to shoot, then use Slow motion to build the habit of shooting by that point.

The Squadding add-on allows up to 6 shooters to practice together, taking turns, with individual scores and gun settings maintained for each.

Setup a squad

1. Define all shooters and their guns (same as single-user mode).
2. Edit → Squads → New squad — enter a name and tick up to 6 shooters.

Start a squad session

1. File → Start squad session → select squad → OK.
2. Select layout, mark absent shooters, have each shooter log in (enter password if enabled).
3. Each shooter selects their gun; click OK to begin.

During the session, DryFire shows each shooter's score in the sidebar, highlights the current shooter, and displays the next target in the preview window. At round conclusion, statistics for all shooters are shown and can be printed or saved as PDF.

The Trap Exercises add-on lets you (or your coach) create targeted training plans for ATA, DTL, or ABT layouts, focusing on specific angles or wedges of the pie.

Exercise types

• Fixed angles — Define up to 10 specific angles (e.g., 10° left, 20° left, 25° right). DryFire shuffles them. Repeat an angle more often by including it multiple times.
• Wedge of the pie — Define a center line angle and oscillation range for random angles within a wedge. 0° = straight away; negative = left; positive = right.

Hit criteria options

• Based on pellet energy (default) — Full physics calculation.
• Maximum pointing error — Hit if shot cloud center is within a set distance from clay center.
• Maximum pointing error & range — Combination of both.

Create plans via Edit → Training plans. Start a session via File → Start training session. Use Ad Hoc for a temporary plan without saving. Results shown on Training session results dialog with per-exercise statistics, printable as PDF.

Course Designer lets you create Sporting and FITASC layouts with traps, stands, trees, hills, fences, and walls/banners.

Key concepts

• A trap releases one clay. For two clays from one spot, create two traps at the same location.
• A target = a combination of one stand + one or two traps. You must create targets explicitly — just placing traps and stands doesn't create shootable targets.
• A round = a sequence of one or more targets.

Editing objects

• Trap: Click the red square to set height; drag the orange landing circle to change distance/angle; click the orange line to set oscillation and velocity.
• Stand: Click the blue square to set height and name; tick safety cage if desired.
• Trees, Fences, Walls: Click and drag to resize/rotate.

Keyboard shortcuts: Ctrl+C copy, Ctrl+V paste, Ctrl+Z undo, Ctrl+Y redo, Delete to delete selected objects.

DryFire can log every shot you take. Shot logging is off by default — enable it via View → Report generator (or Export previous shots data) and answer Yes when prompted.

Replay shots

View → Replay previous shots. Use Previous/Next toolbar buttons to move through results.

Export to CSV

View → Export previous shots data — exports a .CSV file openable in Excel.

Report Generator (add-on)

Filter shots by shooter, layout, target, shot number, or date range. View statistics including: average shot time, average distance at closest approach, average pointing error, hit percentage by trajectory type.

Compare multiple shot sets side-by-side on the Statistics dialog. Print or save as PDF. Enable auto-statistics at round end via Setup → System Configuration → Show statistics after shooting a round.

GunMotion (add-on) tracks your gun movement during practice using an iPhone mounted to your gun.

Setup

1. Install the DryFire GunMotion iPhone app from the App Store.
2. Attach your phone securely to your gun (a bike handlebar mount works well).
3. Setup → Gun motion — set phone orientation relative to the gun.
4. Ensure phone and PC are on the same network.

After each shot, the gun motion track appears as a faint line alongside the shot result. Click an item in the Gun Motion sidebar list to review any shot's track in detail.

Reading the track: Arrows indicate direction of travel. Red = before first shot. Green = after. Closely spaced arrows = slower gun movement.

If you have the Report Generator add-on, you can upload DryFire scores to your myclayshootingrecord.com account to compare practice scores with competition scores side-by-side. Requires internet connection.

Go to Subscription details… in DryFire and enter your MCSR email address. Choose when to upload:

• Scorecard upload button — manual upload anytime.
• After every round — automatic on round completion.
• When I finish using DryFire — uploads on close.
• Ask me after every round — prompts for confirmation.

The Projected Menu allows you to control DryFire by shooting at the wall — no keyboard required. Enable it via Setup → Projector options → Use projected menu → OK.

To open the menu: shoot at the area of the wall the simulator head is pointing toward when no target is active (e.g., the current launch point). Then shoot at the desired menu item.

If the menu appears unintentionally, wait briefly for it to dismiss, or shoot around the edges of the menu (not at any item) to close it immediately.

The projected menu includes: layout selection (8 layouts), muzzle re-alignment (ALIGN), and other common functions. Contact DryFire USA to change which 8 layouts appear in the menu.

DryFire fully supports disabled shooters in wheelchairs. The simulator can be positioned to the side of the shooter rather than directly in front. Once positioned, tell the DryFire software the simulator's exact location relative to the shooter — the software calculates all necessary adjustments automatically.

The most common cause is too much infrared light in the room. The camera ignores shots when it sees a spot larger than 20 pixels (background infrared from sunlight or bright lights).

Quick test

Wait until after dark. Turn off all room lights except your PC screen. Close all doors. Try shooting. If it works → you have an infrared lighting problem.

Fix infrared problems

• Block all outside light (windows, doors, gaps).
• Do not have any light source directly in front of the DryFire unit.
• Remove spotlights or "hotspot" light sources aimed at the shooting wall.
• Do not have windows, doors, or lights behind a background canvas.
• Use fluorescent or LED lighting (least infrared output).

If the room is not the problem, proceed to gun assembly troubleshooting below.

Step 1 — Check the trigger switch and LED

Press and release the trigger switch while watching the red status LED on the SGA. The LED should flash each time (on press in Press to Fire mode, on release in Release to Fire mode). If the LED does not flash → replace the CR2032 battery first before assuming a hardware fault.

Step 2 — Replace the battery

1. Remove the 4 screws from the bottom of the SGA box.
2. Replace the CR2032 coin cell battery.
3. Replace the cover — do not overtighten the screws.
4. Test again. If the LED now flashes → battery was the issue.

Step 3 — Check the muzzle laser

In a dark room, hold the SGA about ½ inch from a piece of white paper and press the trigger. You should see a faint reddish flash. If no flash after a fresh battery → contact DryFire USA for a replacement SGA unit.

Step 1 — Check the trigger switch

With trigger switch plugged in, press and release while watching the red LED. If LED flashes → trigger switch is GOOD. If not, unplug it and short the two recessed pins in the trigger box with a small screwdriver. If LED flashes → trigger switch is BAD. If LED still doesn't flash → trigger box is BAD.

Step 2 — Check the trigger box (batteries)

If trigger box is bad, replace the 3 × LR44 batteries (large flat side touching the spring). After replacement, test again. If still no LED flash → trigger box is BAD and needs replacement.

Step 3 — Check the muzzle laser insert

In a dark room, hold the muzzle insert about ½ inch from white paper. Press trigger. You should see a faint reddish flash. If no flash: either the trigger box or muzzle insert is bad. Call DryFire USA (1-877-357-1485) and order both — return the good one for credit once identified.

Irregular, jerky, or wrong-direction laser movement almost always indicates a faulty servo motor. Servos are the only moving mechanical parts in DryFire.

Other causes (USB cable, PC board, firmware, software) would stop all movement entirely — not just cause deviations. A bad USB cable causes no trajectory at all, not a jerky one.

Servos: what to know

• Not repairable — only replaceable.
• Do not oil or grease.
• Available from DryFire and from model aircraft hobby shops worldwide.

What to record before sending in for repair

1. Left or right head (as viewed from behind).
2. Layout name and target name.
3. Distance/time along the trajectory where the problem occurs.
4. A sketch of the trajectory.
5. Your guess: vertical or horizontal problem?
6. Your contact information and how long you've owned the system.

This almost always means the muzzle insert has shifted since the last alignment. Recalibrate the muzzle insert immediately:

1. Click the Align button on the toolbar at any time — you don't need to stop practicing.
2. Take a careful shot at the laser dot using your bead to cover the dot exactly. No lead.
3. Click Check to verify the alignment is centered.

If the problem persists, also check that the insert is fully and correctly seated in the barrel.

Some graphics cards have bugs in their OpenGL firmware that cause blank or solid-color screens in DryFire. To fix:

1. Go to Setup → System Configuration → Advanced button.
2. Tick Enable software rendering.
3. Click OK to close dialogs, then restart DryFire.

• App doesn't connect to DryFire → Check that your phone and computer are on the same network (same Wi-Fi).
• Gun motion track is upside down → Check orientation of the phone on the gun. Rotate it 180°.
• Gun motion track is completely wrong → Check that the orientation selected in the Gun Motion Settings dialog matches the actual orientation of your phone on the gun.

When returning a unit for repair, include a written description: which head, layout/target name, trajectory sketch, type of problem (vertical/horizontal), your contact info, and how long you've owned the system.

Servo motors (the moving parts inside the DryFire unit) can move slowly or sluggishly when cold or when the unit hasn't been used for a period of time. This is normal behavior.

Allow the unit to warm up to room temperature before use. Do not move equipment suddenly from cold to hot environments — condensation can damage circuitry.

Store the unit where temperatures are between 10°C–60°C and humidity is 10–80%.
