Same as others really like it as I shoot at many ranges where going in front of the bench is prohibited. I use duct tape over the strap for a belt & suspender approach so I don't loose a shot string. Also a plus is that ambient light doe's not seem to affect it. I wish there where an easy way to calibrate it but I guess that is the same for all chronies. Check a known load or use two chronographs are the only way I know how to check. I got lucky with my Forbs rifle sight in with the Magneto and when I took it off I was just shy of 2 inches high at a 100 where I wanted to be, I think it took all of two clucks upwards.
Even if you have another chrony the magneto is so convenient that it will probably get more use.
