Light Gun for PC Setup Guide: How to Get Started | Aim First

Guide

A Sinden Lightgun ($114.99) or an Ultimarc AimTrak ($120.00) turns a flat-panel PC monitor into a working arcade cabinet.

Buying the wrong tracking type sinks most first attempts. Sinden’s gun reads the monitor image itself, so a visible border does the job an infrared bar would do; Ultimarc’s AimTrak ships that bar and reads it directly. Both connect over USB and run on the display you already own.

Three things separate them: what you mount near the screen, what you install on the PC, and how far aim drifts when display settings change. The numbers come first.

Which Light Gun Works On A Flat-Panel PC?

Both the Sinden Lightgun and the Ultimarc AimTrak work on a modern flat-panel PC monitor, and they aim by completely different methods. Sinden tracks the display image with a camera built into the gun; AimTrak tracks an infrared LED bar that mounts on or near the monitor.

The Sinden Lightgun lists at $114.99 in the US and needs no sensor bar, no external power supply, and no console. Ten inputs cover the trigger, pump action, buttons, and off-screen reload. Sinden’s published specifications list Windows 7 through 11, Linux, Raspberry Pi 3B+ or higher, and MiSTer.

The AimTrak light gun with recoil lists at $120.00 in black (C-ATE0BK), red (C-ATE0RD), or blue (C-ATE0BL). It emulates a USB mouse and game controller with no drivers, includes a 4-meter USB cable and the LED bar, and calibrates without host software. Ultimarc rates it for CRT, LCD, and plasma at distances down to 2 feet (600 mm), with up to four guns on one PC.

Console play is a separate project.

Kit pricing matters for a build. The AimTrak OEM electronics kit runs $44.00 with the camera module, USB cable, 2.5-meter extension, trigger connector, and 1.5-meter LED-board cable. The second-gun kit without an LED bar is $36.00.

Setting Up A Light Gun On Your PC: The Step Order That Works

The order is the same either way: confirm the PC and operating system are supported, connect by USB, finish the gun’s own calibration, then map buttons inside the emulator or game. Jumping straight to the emulator is why a gun can register clicks and still miss.

  1. Check support and an open USB port. Sinden lists Windows 7 through 11; AimTrak describes support for all PC operating systems.
  2. Set up tracking. Sinden owners install the manufacturer software, connect the gun, and run the on-screen calibration. AimTrak owners mount the LED bar facing the player where the camera can see it, then run the built-in calibration.
  3. Point the emulator at the detected mouse or game controller. Most light-gun titles need the input chosen manually the first time.
  4. Assign trigger, reload, pump, and off-screen actions to buttons you can reach.
  5. Test from the distance you actually play at, then check windowed mode, scaling, and aspect ratio for any shift in aim.

You’ll know it took when the cursor sits under the muzzle as you sweep the screen and each trigger pull registers.

Weight and trigger pull only settle under your hand. Our tested light gun roundup compares the models people ask about most, including how each behaves after a few evenings of play.

What Usually Goes Wrong On A First Light Gun Setup

Failed setups usually trace back to tracking hardware rather than the gun. An AimTrak camera that cannot see its LED bar and a Sinden camera that cannot see the display border both produce a pointer that jumps or lands off target.

  • Buying an AimTrak gun with no bar, or mounting the bar where the camera never sees it. The $36 second-gun kit deliberately leaves the LED bar out.
  • Assuming the emulator detects light-gun input on its own. Per-game mapping is still part of the job.
  • Treating the guns as interchangeable. Cropped or overlayed display images hurt border tracking; an obstructed bar hurts infrared tracking.
  • Running Sinden on Android, which the manufacturer calls very raw beta and not guaranteed across devices.
  • Changing resolution or emulator settings and expecting aim to hold. Display and software changes can force reconfiguration even on a gun that stays accurate when you move.

Start with the display. A Windows 10 or 11 PC showing an uncropped fullscreen picture suits the Sinden gun with nothing extra to mount. A CRT, a plasma panel, or a cabinet running several guns at once points toward AimTrak at $120.00, with the $44.00 OEM kit covering a second build.

Common Questions

Does A Light Gun Work On A Regular LCD Monitor?

Yes. Both guns here run on ordinary flat panels. The Sinden Lightgun reads the display image through its built-in camera, and Ultimarc lists the AimTrak as compatible with CRT, LCD, and plasma screens. Neither needs a projection screen or a specialized display.

Can Two People Use Light Guns On One PC?

Ultimarc lists support for up to four AimTrak guns on a single PC, which covers two-player cabinet builds with spares. Sinden’s published materials do not state a multi-gun figure, so confirm two-player support with the manufacturer before buying a pair.

Do PC Light Guns Need Drivers?

The AimTrak needs none. It presents itself to Windows as a USB mouse and game controller, so the operating system picks it up immediately. Sinden requires installing the manufacturer’s own software before the gun reports aim correctly, and that install includes the calibration routine.
