OK I've searched and cannot find this. I have a Game/Hunting Laser Range Finder(Osprey International EMC4 Comet, www.miniosprey.com)? It does measure speed. So can I use it to test my Blinders after they are installed. The laser type is a Class 1 with a 40mm laser lens. How does it compare to a real laser gun, I am sure it is much less powerful.
