Each plate comes with a 17 inch long 3.5mm male plug for connecting to a CED8000 timer. When connected, the stop plate sends an impulse signal to the timer each time it is hit recording the time of each hit on the timer itself. Perfect for club matches where the timer is used to start the course of fire and the stop plate when hit ends it. The competitor's completed course time is then registered on the timer.

Each stop plate includes a 7? long steel extension arm for attaching it to wood target sticks. Adjustable sensitivity makes this stop plate a fantastic training device for a wide range or Airsoft, BB, and Pellet guns. 3x AAA batteries required (Not Included).
