Skan reads the same as my combro at default settings. So they will be record 770-780fps even if the shots don't match the same when fired they fall into the same bracket.
I don't know about a Kestrel John have you considered prayer or a deal with the Devil.
I could live with a 10fps difference, but not sure that 30fps is sensible!! I am going to have to double check a rifle with another chrono to be certain as to which is wrong, but 99.9% sure it's the Skan.
It's never been used much at all, but has sat for quite a long time, not that that should make any difference.
