Zeiss conquest 15x56 are great for long range glassing - Zeiss Conquest HD 15x56mm Schmidt-Pechan Prism Waterproof Binoculars

These 15 power binoculars have been great when glassing off a tripod in open country. I live in the west and open country glassing is a must. I have found that the extra magnification allows you to find and classify game at long range much better than 8 or 10 power binoculars. These binoculars are crystal clear and have never given me any eye strain despite hours of use.
