My old shooting buddy had a past and he thought it was THE THING till I brought out the 338 and kept blowing the thing around so bad it would not get a reading. I bought a pro chrono for $100 at Cabelas while on my way to see my son in Idaho. We took that $100 cheepo out in the desert where all the GIs shot everything you could drag out there and set it up on a shot to crap TV set. First shot with the 338 and it went flying through the air and hit the ground rolling. I thought I just pissed away a $100. Went and picked it up and it was still working and had caught the speed. Just about ALWAYS caught the speed unless you just plain missed the eyes. Trusted the readings on that on till I voided the warranty with a 40 gr. Nosler @4080 fps thru the screen. I bought another one and not too sure it is as good as the first one.
