Very good
unfortunately it was delivered a day late because I was already at the shooting range and couldn't test my own. but had the opportunity to use the predecessor Mach 4. Great device for analyzing reloaded ammunition. My SD was rated 2.6-3.0, which I really liked and I could also see the quality of the target. I was out at 300m with the Sabatti Tactical and the Ruger Precision Rifle, both in .300win Mag. The goal is the 1250m in May. I'm excited and looking forward to it. can only recommend the speed tracker, small, compact, reliable. Greetings from Germany Silvio. Ordered on Sunday and delivered on Friday.
