To all concerned about beating a dead horse!, I believe the IBO's position on binoculars above 8 power is the correct one, studies have been done by independant sources showing that you can use higher power bino's for yardage judging. The feeling I get from the IBO, by the way that they lay out there ranges so that you can't see the previous target so that you have to JUDGE yardage and make a good shot! This is a dead horse!!
Not entirely accurate. Straight from Ken Watkins.......there was ONE manufacturer of binos that had a ten power pair with an adjustment wheel that allowed it to be used as a crude rangefinder. Not all 10x, just one brand.
