I recently purchased the vortex model seem to be very happy with it I've ranged over a thousand yards in low light. I've used it on 3d trails shooting multiple angles and up 120 yards with my bow and was accurate. I used it to sight my rifle in and shot accurately out to 300 plus. it seems very durable like the lanyard and the clip. it has the mounts for mounting it to a Tripod. however it did seem to struggle a bit in the low fog but I imagine that most rangefinders do have trouble in fog. that's hunting and it can't be perfectso I don't have any info on the other brand but the vortex is nice especially with a lifetime warranty no matter what
