Foreman, I have a couple of them and would seriously have him look at the Jim White tripler versus the Swaro doubler. The tripler is alot easier to put on, doesnt require taking the eyepiece out of th bino and works better. Neither the tripler or doubler will replace a good spotter, but if he is set on getting something, the tripler is by far the best money spent. I believe the tripler costs 250.00 and if Brian doesnt sell them here, he can call Jim White at 1-928-635-5376........... Thanks, Allen Taylor......
