The Opal All in One Timing System is an amazing piece of technology, containing 4 antennas. Great for smaller stand alone events and as a backup to very large events. Fantastic read rates. No separate timing system required.
Inexpensive timing solution for high end events. 100% read rate. Simply tape down the wire across your point or the road. The Loopbox either stores or transmits (WIFI) your chip read to your USB Active System.
