The scope facilitates the viewing of long range items and precise aiming of the laser beam. When using high quality laser devices that emit a small laser any movement will usually net you an incorrect reading or no reading at all. Most of them are tapped on the bottom side for mounting on a tripod or camera fitting mount to keep its movement while in use to a minimum.
Its not meant to be mounted on a fire arm its meant to be used as a stand alone system.
John Burns from Best of the West uses a similar if not the same LRU device.
Its a high quality device capable of extreme ranging and accurate repeatability. Other units exist and prices only go!
I had forgotten about that unit. I owned one for a few years. It is quite good. There is a hand strap for holding it when you don't have tome to put it on a tripod.
It's been a while. I vaguely remember putting a different scope on it because the included one wasn't very good.
it looks like a good unit, I like the scope to be able to pinpoint the laser, I have some problems with my newcom at exactly pinpointing the laser getting different ranges each time
