I have used the LRM 2000 Pro for a couple of years.
+ cost ( at the time of purchase, no reliable 1.5k+ rangefinders in the $500 range )
+ targeting reticle matches the actual beam
+ good ranging capability in fair conditions: At one of my favourite locations, I've gotten a repeatable 1360yd on cars in front of a cafeteria at 1400 yd, 1800yd on buildings, 1k on small trees, 1300+ on large trees etc. Don't have experience on fur at 500+ unfortunately so can't comment on that. But at least on ground features like rocks and trees, it measures well.
- exceptionally poor optics in the monocular, completely worthless in the dark without NV
- consumes batteries, including when not in use
- fails in cold weather ( measures for a while, then gives a low battery warning and goes silent until warmed back up )
- fails in light snow or fog ( will not measure )
All in all, I don't feel the need to upgrade into another mid-priced monocular model. I would only consider a Zeiss or Leica bino rangefinder worth upgrading into. YMMV.
