Arch, I am a diehard bowhunter, but also dabble with single shots during firearm season...... Clarity of the Leica's is like no other, I love when people mention light gathering capabilities.... I own a Bushnell Yardage Pro 400 (1st laser range finder to come out), then proceeded to buy my father a Leica LRF900, after using it in the field I purchased the LRF700 PM. Before purchasing my own, I asked to use my friends Nikon and anothers Swaro..... Both great but, the Nikon, like the Bushnell has an aiming problem when you are facing toward the sun, the LCD aimpoint sort of fades and that was an issue with me because I have some morning stands which face to the east....

As for light gathering capabilities, you can pretty much use these things when it is almost pitch black out, I really don't know if there is such a thing as more light capable w/out being night vision... Its like saying something is more dead, than another. In my book dead is dead. I would even say that they bring in more light than my 40mm obj. lensed scopes...

The only reason I chose the Leica over the Swaro, was price. The Swaro was a bit more then i wanted to spend.... But I did love the Swaro!!!

Being a bowhunter, your Nikon 400 may be all you need, once you range some landmarks, thats all you need..... I just like to look at things a ways off to determine whether or not a buck in the distance is a shooter or not.
