Breakbeam vs. Bouncebeam

Breakbeam eye have two components: The Emitter and The Receiver. The Emitter is simply a device that can produce a relatively focused beam of light. Like a laser. The Receiver can detect when this beam is pointed at it. The Emitter and Receiver are placed on opposite sides of the marker in a configuration that shoots the beam of light through the barrel. When there is NOT a paintball in the chamber, the Receiver detects the beam and sends a signal to the control board not to fire. But when a paintball enters the barrel, it "breaks" the beam of light and makes the Receiver tell the control board that it can fire.

A Bouncebeam eye works in a similar way. It has an Emitter and a Receiver. But unlike the Breakbeam eye, the Bouncebeam eye has both Emitter and Receiver in the same housing. So when the Bouncebeam eye is installed, it shoots a beam of light into the chamber. If there is NOT a painball present, the Receiver gets no signal and tell the control board not to fire. But when a paintball enters the chamber, the beam of light reflects or "bounces" off the paintball and into the Receiver. Allowing the Receiver to tell the control board that it can fire.
