Yep, I'm going to be getting one in the next week, I just can't decide whether to get the 550 or the rifleman 550 with the ARC. I just have to figure out if the elevation reading thing is worth the extra $85.
I traded my bushnell rangefinder in a scope swap this summer, I was tired of the fact that it only would consistantly range out to about 170 yards. I liked the nikon 550 the guy I prarie dog hunted with had, he got clear readings out to 400+ yards. Seeing is believing, I'm buying a Nikon!
