Shot timer

[Florida_Man]

Anyone use or know of a shot timer that works well with air rifles?

I am planing a timed event for my next office shooting challenge. It will be trivia based and they have to shoot the bullseye of the correct answer.
It will most likely be a 12 fpe 177 rifle fwiw

the "splits" shot timer app for android has picked up my sig virtus very very well.

i use it to shoot steel challenge style shooting.

free is good lol
