Here is a small review of a free shot timer app you can download to your phone. I do apologize for the low lighting in the range. We shoot more low light than anything and I didn't have any of the other back lighting set up at the time.
I'm very pleased with the free shot timer for our training purposes. It has helped me improve my draw from concealment time by .2 seconds with just a few hundred practice runs. You may be thinking this is a lot but you can go through a few hundred runs in an hour or so. You may also be thinking that's only .2 of a second, but you never know when that .2 will be the difference between life and death.
