My friend got one of these, and TBH i am stomped.
It will extremely often miss a shot / several shots in a row completely.
It will some times ( like 1 in every 5 shots ) list a speed for a shot at least 1/4 of the actual speed of 970 FPS
And it have a couple of times barked out a speed of over 3000 FPS
I think my friend is lucky the used chrono are just from December and he got at a very low price, which seem to be for good reason
The damn thing are of course fully charged and fully updated ( with the extended sleep update FW )
Needless to say my old FX pocket chrono on his rifle perform as it should.
