If your sport involves getting a ball towards your opponents at high speeds, the Pocket Radar Ball Coach can help you improve. It measures the speed of balls hurtling towards or away from it and instantly displays the result on a highly visible screen. Trying to beat your score motivates you enough but to able to instantly see the result of your effort is even better. The Ball Coach records the last 25 speeds and automatically finds the fastest speed. It can be used hand-held or with a tripod so can concentrate more on coach or training rather than operating the radar gun.
