i like simple and reliable
i like small and light weight, easy to keep in range bag

That and cheap why the one I use the most is the shooting chrony, it’s the one that’s always there ready to go and the “good” ones that cost more are put up.

Angles of sunlight can be an issue at times but I have even used it at night before with white cardboard and a flashlight.




Whenever I wake up to a cloudy day I try and think of there is anything I should chronograph. Don’t even need sky screens, just set it down, turn it on and start shooting.

great idea, the G2, that I use has it's own lights for dark rooms, like garages or early/late shooting times. over 1000 rounds thru it and about 3 errors. not sure why, one was low power after 6 hours, so I plugged in the unit to my truck and recharge the battery.

This is the Wi-Fi report from my G2 Chronograph set out ten feet from CZ 452 shooting 50 yards. One flyer or this could have been a .23 group, This why I'm testing
