It locks readily, and is very consistent between measurements. Optics are good and easily adjustable.

Very prompt and courteous. Would do business with them again in a heartbeat. Great bang for the buck.

Slope is useful and the switch to deactivate slope for comps is great. Very good range finder,gives actual yardage plus the slope distance.

Opened it right away, was sent a dirty grungy used unit. It is in accurate, and the laser is very unstable!

The range finder is 10-15 yards off. It vibrated to say it was on the pin. It jumps back and forth between yardage when you shot at your target.

This product is no bueno! It adds little to nothing over a gps watch and a free smartphone app. There are no features in this that make it specific or advantageous to golf.

Missed the return window by a day. Replaced batteries 2x, and brushed off contacts. Just will not turn on most of the time. Maybe it can be recalibrated.
