Hi Russ
It was recommended to me by a British pistol club member when talking about scoring. At less than the price of 2 packs of RWS R10 I thought it would be worth trying. Loaded onto an iPad no problem, able to set up and use without even having to refer to FAQ so passes intuitive use test 😉. When you get group holes it can be worth repeating the scan/photo after rotating the card if it isn’t getting a good picture, this could be because I’m using white paper behind the target rather than the light box setting that they offer (use iPad as light box and phone as camera).
