I purchased these to add
I purchased these to add to my teaching kit. I recently became a Hunters Education instructor . Next to firearm safety, the most important subject taught is hunter's ethics. A portion of each class is titled ‘The Game Trail,' where numerous hunting scenarios are staged. I have expanded my training to discuss the ethical shot, by rifle or bow, and how distance affects everything . My Leupold ranging binoculars dispel a lot of myths and hubris. Next year I'll save up to purchase another pair of ranging binoculars….
These are my favorite optics
These are my favorite optics I've owned & the clarity of the glass is amazing. I actually like the weight of them too because they are stabile even when you're getting hit with some wind. The range system is what you would expect from leupold with lots of math in the software. They are very accurate and being on a bino platform has been super nice. Most of the western spot and stalk hunts you have to be able to range a individual tine on an animal even if they are bedded in brush. It's certainly not always as cut and dry as a wide open range on the body. With the range system in this bino platform you can focus through it all and range with pinpoint accuracy. It's came in clutch for me in many situations. This is my 3rd season with the BX platform and I won't change now. I just ordered the new one in a 12x50 as well.
Both the binoculars and range
Both the binoculars and range finding quality are excellent. Range Finder is accurate and have used it to acquire range of targets out to 1200 yards. For hunting in low light it has been superb and in conjunction with with my leupold rifle scopes has been exceptionally successful in elk, antelope, pig, deer and small game.
