Bushnell makes a range of optical products, including a line of binoculars. The binoculars are marketed for bird-watching, wildlife watching, field use and general recreation. Bushnell binoculars have gas filled optical chambers that provide fog-free viewing. Adjustable focus and eye pieces complement the optics. Bushnell doesn't recommend that you attempt any repairs to the lenses or glass because these repairs should be done by an optic professional, but there are some simple repairs you can do yourself.
Tighten and adjust the focus dial screws. When the focus dial is too loose, tighten the screws. If the focus dials are not turning as needed, turn counterclockwise to loosen them.
Locate any cracks along the rubber or optic chamber plastic. If present, squirt a small amount of clear super-adhesive into the crack, wipe off the excess while wet and let the remainder dry to seal the cracks.
Wipe off all lenses with the dust-free chamois cloth. Look through the barrels as you wipe down and clean to make sure all small dust particles are removed. Spray the lenses down with the compressed air and get all remaining dust particles off the glass.
Use the adhesive and tweezers to fix broken strap holders. Pinch the holder together at the crack with the tweezers and squirt some adhesive along the cracked seam. Let the adhesive dry.
