I saw some neato-whiz bang units here;
www.NatchezSS.com .
They have a cool set of binos/range finders in 2 sizes. They are not cheap but have protected lenses(fog rain gunshots-shock).
They have another "demo" Bushnell model with all the bells & gizmos built in.
It's a rifle scope but it's built for rough use/outdoor/hunting.
Natchez Shooting Supplies also sells a few laser rangefinders & optics for target/hunting use.
