The Nikon ProStaff 550 Laser Rangefinder is a waterproof and fogproof "vertical" style rangefinder intended for use primarily by hunters. It offers distance measurement ranging up to 550 yards (or 500 meters) depending upon lighting conditions and the target's natural reflectivity, and uses a distance priority target system so that if you're ensconced in brush it will ignore these foreground targets and display the distance of the further recognized object. The ProStaff 550's streamlined shape, comfortable 6x magnification, and compact 21mm objective diameter allow it to be easily carried and operated with a single hand. A practical choice for a hunting rangefinder made by a quality sport optics company.

This item does as it suggests with no bells and whistles.
Pros:
Fast and accurate
Lightwieght
Weatherproof
Cons:
Battery cover - I taped mine up straight
away and have not had a problem
Eyepeice - not as clear as I would have
liked and you have to push your eye into
the cup to see your target clearly.
Summary - I would have given this product 5 stars except for the eyepiece - viewing through the lens is Ok but not great. I know this is a budget item but I expect greater for the money.

Comments about Nikon Prostaff 550 Laser Rangefinder (Green):
Have not had a chace to hunt with it yet, but I have picked up several targets and have checked them several times at different times of the day and different weather conditions and always get the same readings. I check a couple with an old 100 foot tape and the readings are right on. Excellent product and excellent service.

I use this to supplement my digital images with and accurate reading of distance to subject in wildlife photography.
It is easy to use in the wildlife situation in which I do my photography. The guages are easily read and measurements are concise.
I haven't had any negative affects using this equipment.

Comments about Nikon Prostaff 550 Laser Rangefinder (Green):
Use the Nikon 550 for golf. Gives accurate distances and helps immensely with club selection.
Well built, small, light and easy to carry around.
Great value.
When the flag is still though, it is tough to pick it out from a background. Pinseeker technology from Bushnell might help there, but I have never used a Bushnell Rangefinder. Ranging to players on the green or the green itself works well as a substitute.
