Has anyone played with any shot timers for trap shooting? We are continually looking for ways to teach/coach trap shooting to the new youth shooters. One issue that a lot of people have is the timing of the shot, either too quick or riding the bird too long. We have the idea of clock that shows the time between the call of the bird and the shot. We use a stopwatch now but it slows down the timing of shooting if we show each kid and can be incorrect by not paying attention. Any thoughts?
