Colorado Time Systems INF-SSM Infinity Start System 110/120V - The Infinity Start System makes an excellent entry-level start system, and its lower cost makes it a great choice for smaller pools and recreation centers. It is an easy-to-use portable start system and limited public address system. The built-in 360 degree strobe flashes with the start signal. This gives timers and officials a reliable start reference and provides a visual cue to athletes that are deaf or hard of hearing. Additional strobe lights may be added.
