Used the speedster 3 and speed screen during cyclist races, Hpv(human powered vehicle) races and during velodrome cycle training. Works extremely well. Will not register under 16kph but when tested next to a Qld Police lazer radar was accurate reading the same over a half an hour period. Very impressed. The transmission distance is about 50m and gets less as the batteries in the gun go flat. Very bright screen and large numbers easily seen well over 50m. Would like a power adapter for gun as the life of the batteries in the gun is 2-3 hrs continuous use. Heaps of great comments from spectators and officials. Great training aid for track(velodrome) racing ie. The speeds increase when you bring the gun and sign out. Would recommend.
Pros: Accurate, bright and clear. Easy to use.
Cons: Battery life.
