I have a Callaway LR 550 laser rangefinder by Nikon. I have used it three times and I really like it. It gives accurate distances in an instant. Most importantly, it has built in image stabilization like video cameras. If you hold down on the button it will scan the distance to various objects for 8 seconds. It has automatic shut off, so you can point and shoot, get distance and put it down without worrying about turning it off. It is waterproof as well. There is not much in the way of reviews online since it is new this year. I was considering the Bushnell Y2 tour, but I did not like the fact that it did not have image stabilization, was not waterproof, and did not have a scan feature. Does anyone have any knowledge of the Callaway rangefinder?
