As advertised - Nikon RifleHunter 550 Hunting Laser Rangefinder w/ ID Technology

I was warned to not expect a rangefinder to lock on a prairie dog at 600 yards, so I did not expect too much. This one works just fine, and locks on larger objects easily. Buttons are straightforward and simple.
Pros: easy to use
Cons: sometimes vague, hard to get to lock on small objects
