Nikon Laser400 Rangefinder

Nikon's Laser400 may be one of the smallest rangefinders on the market, but its outstanding performance makes it an ideal for bow hunting and rifle hunters. Enclosed in a compact and water-resistant design, the Laser400 measures distances out to 100 yards with an accuracy of half a yard and from 100 to 437 yards with one-yard accuracy. Its bright, clear optics, adjustable diopter, 8x magnification, 20mm objective lens, and 330 foot field of view ensures the best imaging possible.

The rangefinder also has two modes of operation--standard and rain--to adjust optimally to the environment. At only 7 ounces the Laser400 is a powerful tool in a small package. NOTE: Lithium battery sold separately.
Customer Review: ... and the 8x magnification is good too
while my game isn't quite good enough (yet) to need to know if the pin is 87 yards out vs. 85 1/2 yards (which this is apparently accurate enough to tell you), i do benefit from knowing that the green is in the general vicinity of 85 - which is fortunate, because if needed to know precisely I'd have to mount this thing on a tripod - the hand-held aspect of aiming at something a hundred or so yards away means that (at least in MY hands) you're going to be lucky to get the same reading twice. Which isn't to say that this is not a useful tool - like i said, i only need to know ABOUT how far i am to pick the right club --- and then i can use the 8x scope to see if i hit it up next to the hole!
Customer Review: Got batteries
I felt the product should be more clearly marked. For example stating that the item needs a special lithium battery, so that if the item was purchased as a gift as the one I purchased was, I could have also purchased the battery. This made for a very unpleasant Christmas for myself and the person I purchased the gift for. I can not rate this product until I purchase the battery.
