How does it work?

Tachyon works by detecting your outgoing shots using a custom barrel-mounted sensor.

Setup is easy and simple. All you need to do, is to attach the barrel sensor, and the Tachyon computer to your weapon. Then, you use the included battery splitter cable to connect the device to your weapon's battery (No soldering or re-wiring required).
