I use the Nikon 400, it works great for bowhunting. If you are looking for a dual purpsoe though this wouldn' t be the best choice. Your target has to be fairly large to get a reading past three hundred yards. It won' t rannge an antelope much over two hundred, and deer over 250, haven' t tried it on anything big like moose or elk. It never fails from 40 yards in so it suits my purpose fine.
