[QUOTE="LouBoyd, post: 304702, member: 9253"] It's good to know what the divergence of your rangefinder actually is. You may find it in the specification sheeet, but you can actually see the beam and measure it using a night vision scope or a camera with IR capability such as one of the Sony "nightshot" cameras or most cheap black&white surveillance cameras. The beam size vs distance is not the same for all rangefinders and for many the beam is larger than game animals which might be targeted for "long range hunting". Most civilian rangefinders can be detected with a ccd camera. Most military rangefinders cannot as they typically work at wavelengths longer than the cutoff of silicon. [/QUOTE]
