Standard rangefinders are functionally the same as rangefinding binoculars, but there’s also quite a bit of difference in how you deploy each in a field setting. Standard hand-held rangefinders are monoculars, in that they have a single lens. That second lens is actually a sensor that measures the laser return. Laser rangefinding binoculars have two lenses. So the biggest differences are size and optical performance. One of the most important attributes of a rangefinder for bow hunting is that it can be operated with one hand. The advantage here goes to the monocular. But the best rangefinding binoculars for bowhunters have an open bridge that enables one-hand operation. An advantage of ranging binoculars is that they can be easily stabilized with two hands, an important consideration if you’re trying to get the range on a small, moving target.
