Depends on what I am doing but my Favorite for matches and practice is the loud PACT. Simple to use and shows the time, last split, first shot and number of shots, without pressing any buttons. Does the time not seem right?, how many shots were recorded, instantly without any fiddling.
Slightly less info but can be adjusted to work perfectly in ranges with echos, suppressed, etc, is the R-U-Ready.
For steel I like the CED 8000, with the big board everyone can see the times. It can also activate things at the buzzer as well. It’s also good for matches if you have score keepers that don’t keep up writing down the times because it has a memory of past runs.
I had others, the CED 7000 has a display that I can’t read wearing polarized glasses, so I have to lift them all the time to read it, it also has a buzzer frequency that makes it very hard to hear if you have tinnitus and unlike all the others, doesn’t have a battery you can swap out for a fresh one. So if you forgot to charge it, you don’t have a timer, the others, just pop in a new one.
