[QUOTE="Pdvdh, post: 522696, member: 4191"] [b]Re: Rangefinder Field Test: Swarovski 8x30 Laser Guide Vs. Leica CRF 1600 Rangemaste[/b] Based on my experiences with laser rangefinders, I would recommend ranging those 'open fields' you intend to hunt with range-able objects prior to your hunting/shooting of the groundhog. Have someone stand in various locations in the field holding a large (larger than a groundhog) reflective target, sign, etc... Then range the distances to that person and record those ranges for future use. Reference those notes and interpolate as necessary to the location of the groundhog wherever he sticks his nose above the grass. Either that or place a fake Christmas tree at a variety of desired locations and range those distances. Record the notes and interpolate to estimate a distance to the little critters - wherever they happen to appear - from your recorded ranges. Your scenario helps explain why I range evergreen trees when comparing the ranging performance of laser rangefinders. There's no reasonable way to compare their performance while ranging field rat or groundhog-sized objects on a level field that's void of any prominent topographic relief. A boom truck like the electrical lineman use to work on overhead power lines would be ideal. You'll need to increase the angle of the shot on any extremely flat ground surface in order to expect repeatable ranging on tiny objects - because what you'll really be ranging is the surrounding ground surface rather than the groundhog. And the shallower the angle of the rangefinder shot onto a flat ground surface - the greater the inherent error in the yardages ranged. [/QUOTE]
