I've just finished this turning target system, designed for ISSF (Olympic) style pistol shooting training. It's portable and runs on a 12v motorcycle battery.
The ISSF pistol shooting is all one handed, open sight competitions. The centrefire match is for any centrefire pistol over .32. Total of 30 shots (in 6 strings of 5) on a static target at 25m (27yds)
then 30 shots (again 6 x5) on the dueling target. 3 second face time, 7 second edge time. pistol must be returned to 45 degrees after each shot.
Any other edge/face time and number of exposures can be programmed and has a wireless remote control to start/stop and edge the targets.
