I've had this chrono for a couple months now with no issues. No more having to set up a chrono down range and having to postition it just right. Just slap it on the muzzle and get your data. Everything you need, and nothing you don't. Definitely worth the money, especially if you shoot precision rifle matches.
So often I have left my chrono at home because of set-up time at the range. No more. Strap it on, check the bore height and start shooting.
Very easy to use. Every LRP shooter should have one.
The Magnetospeed V3 is a vast improvement over my previous chronograph. It registers every shot and appears to be very consistent with speed readings, regardless of lighting conditions. I have used it on 22 LR, 204, 6.5, 300 BO subs and supers, 308 and 300 WM with varying sized barrel muzzles. Very easy to set up and use. I would recommend this to anyone wanting a top of the line chronograph.
