Nikula marine binoculars 7*50 water proof with scale
1) Internal rangefinder reticle & compass
2) Multi-coated optics with high transmission coating
3) 7 meter close focus
4) Bak-4 roof prisms
5) O-ring sealed waterproof
6) Nitrogen-filled fog-free protection
7) Central focus
waterproof binoculars keep body tubes airtight, and nitrogen gas is filled. These factors are effective in preventing fog and mold inside an optical system. However, binoculars should not be used underwater. When waterproof binoculars get wet, wipe the water off thoroughly and dry them.
