Review: BOSTRON 7x50 non-floating, not waterproof binoculars $65

Amazon Affiliate Link: https://amzn.to/3Yvuw8C Price as reviewed: $65 7×50 HD Binoculars, IPX7 Floatable Waterproof Marine Binoculars for Boating, Shockproof Rubber Armored, BAK4 Prisms and FMC Lenses, Ideal for Bird Watching, Outdoor Adventure The optics on these binoculars are reasonably good, actually 7x magnification with 50mm objective lenses, so they meet their specifications. Reasonable focus range, IP Adjustment, Diopter adjustment, etc all work great. Eye cups can fold down to use with glasses, but their large 7 mm exit pupil and generous eye relief mean you really don't need to fold them down even with glasses. Views are good in the center, get a little muddy around the far edges, but overall reasonable optics for the price range. However, they are advertised as "floatable", and they sink in fresh water. (They sink relatively slowly, so it is possible they would float in salt water...but it's also possible they wouldn't.) Additionally, when they went under water, a good amount (4-5 tablespoons) of water got inside the left side. The right side did not have any water go inside that I could detect, but the left side had visible pooling and flowing water inside, condensation that made it unusable, etc. Perhaps this was just a QA / manufacturing problem with the particular pair I got.......but perhaps not. So, don't pay a premium for the "floating" or "waterproof" features, but if you want some possibly rain safe 7x50 binoculars the optics were of reasonable quality.
