I've heard of that rangefinder, I think my brother has one that he likes. A year back we were hunting together in the cabin and I tried this device? it's pretty handy for distance measure. Personally, I have no need for such gear. I prefer hunting scopes, I can certainly see why the average hunter feels that a 3-9x40mm scope is just what the doctor ordered. At three power he has all the field of view he needs for most short range shooting and at nine power all the magnification needed to sight in his rifle properly.
