Shot timer for indoor ranges?

[AlphaKoncepts]

Recommendations on a good shot timer for indoor ranges that wont get confused by sound bouncing all over walls?

I use a Pact Club 3. It has an adjustable sensitivity setting, so you might be able to adjust it to work inside.

Agree with the comment above! I've tried my fair share of shot timers, and so far, the Pact Club 3 has worked the best. Both outdoors and indoors as well.
