Looking for a practice timer that can be set for 30 sec. setup then beeps when pre set time is to start then beeps when time is up. Had an old wind up bullseye timer that worked great for practice but can not find a digital timer that can set shoot time and set up time and beeps at the start and end.

Guess no one uses one

Get 2, they are cheap. Set one for 30secs and the other for the total time you want.

Timer App on my phone.
Look for an app that chefs use to set up multiple count-downs. Works like a charm. Practice, practice practice

I also use phone to time at the match, set with large numbers displayed so I don't have to move my head around much.
Remember to turn the volume and ringer off!

I use a cheep egg timer. But it doesn't beep at 30. If you got 2 that would work as long as the one you set for 30 seconds only beeps once. I found that I shoot so quick that time is never an issue unless something goes terribly wrong, so I don't bother practicing with one any more.

I use a cheap kitchen timer like a lot of other shooters. I never really had an issue with running out of time in a match, but it helps in the opposite way. I shoot slower now with a timer. I don't rush any shots because I can monitor my time per shot.
