Review on ⛵ Black Hooway 7x50 Marine Binoculars with Waterproof Design, Internal Rangefinder & Compass - Ideal for Navigation and Boating by Donald Phillips

first, it has a fixed focal length, no adjustable zoom; Second, none of the claims about the strength or mil standard are true; after one-time birdwatching while hiking with light packs, the lens element carrying the reticle moved 90 degrees; Otherwise awkward to use, straps slipping, lens caps falling off etc etc etc I'm pretty sure this is one of the worst optical devices in the known universe.
