Nikon Monarch ATB 8x42 100% Waterproof Fog proof Shockproof All Terrain Binoculars are the best hand-held hunting binocular out in the market that would not cost a fortune.

Incorporating precision-aligned optics for extended viewing, Nikon ATB Monarch 8 x 42 Binoculars have a rubber-armored, ultra-rugged, roof-prism design, with multi-coated lenses for bright, clear images

Based on what I found in most dealer sites, they are claiming that this product comes with a 25-year limited manufacturer warranty. Meaning on normal use this product would probably be around for 25 years or a little less.  Nikon Monarch ATB - All Terrain Binocular has been redesigned with phase-correction coating and fully multi-coated lenses for bright, crisp and clear imaging with ergonomic styling and easily operable controls.

Tough rubber armor and rugged construction of Monarch ATB - All Terrain Binoculars make them perfect for the deer stand or duck blind.

Extra long eye relief and twist out eye cups accommodate eyeglass wearers.
