NOTE: Non-removable cable - Recoil Activation Trigger – Missing important shots during load development or shooting small caliber with a suppressor will be something of the past when connecting the RAT to your LabRadar. The small design of the RAT will not impact materially on accuracy or point of impact change when attached to your rifle with Velcro. The RAT is easy to use and effortlessly plugs into the microphone jack input. The recoil will cause the LabRadar to activate and measure the velocity.
