RangeMaster Sports Timer is ideal for timing horse, track and athletic events. The app interfaces to one of these wireless electric-eye gates (sold separately):
RM-110, RM-101
Use RM-110 for timing events that need only one gate such as horse Barrel Racing, Cowboy Mounted Shooting and other agility events that start and finish on the same line.
Use RM-101 for timing practices where 1/100 of a second timing is good enough
The large numbers are easily readable when a big TV or computer monitor is used to display the time to the audience during events. Works with any size big screen TV
