Helpful Positive Review Fantastic Piece of Equipment by Legacy Reviewer, August 10, 2007
This is one piece of equipment you want in your gear bag. I am a PI and I use it all the time for surveillance and for when I am hunting as well. Pros: Light, durable, waterproff, does the job it was designed for! Cons: none!

Excellent product. Have not used it in cold weather (0 degree f) yet. Own other brunton products and they are the best optics I have used/owned. I would recomend any brunton product. Pros: great size and weight Cons: needs padded case
