Get 12x closer to stars and wildlife, even in poor light, with the waterproof, multi-purpose BOSMA BP1250A 12 x 50 Waterproof Binoculars. They gather lots of light, thanks to the large, fully multi-coated 50 mm objective lenses and 25 mm eyepiece lenses.


BP1250A 12 x 50 Waterproof Binoculars

Excellent Optical System

The fully multi-coated optics deliver light transmission of over 80%. The large 50 mm objective lenses gather ample light, resulting in a brighter image. These binoculars maintain excellent clarity and color fidelity even in low-light conditions like dusk and dawn.

Functional Eyepiece Lens Design

The eyepiece lenses consist of 4 elements in 3 groups to deliver a wider field of view, greater light transmission, and increased edge-to-edge sharpness.

Durable and Built to Last

Boasting a robust, one-piece chassis constructed of aluminum alloy that’s fully rubber-armored, these binoculars offer a secure, non-slip grip and are tough enough to withstand accidental drops and bumps.

25 mm Eyepiece Lenses

The 25 mm eyepiece lenses not only increase clarity and brightness but also make the binoculars more comfortable to look through during long viewing sessions.

Waterproof, Fogproof Construction

Built to handle harsh, challenging conditions, these binoculars are waterproof to a depth of 11.8 in for 30 minutes and nitrogen-filled to prevent internal fogging.

These binoculars are very clear with great magnification would have been 5 ⭐'s but the weight is a bit on the heavy side nice for vehicle camping and bird watching and maybe good for boating.

"over built" is the word that comes to mind. All the working controls are metal as well as the frame and body of the binoculars. Not sure the quality level on the optics, but with some limited use the optics are clear, bright and distortion free. Decent for the price point. These are definitely best for use with a boat, home or vehicle application. They are relatively heavy for hiking or backpacking.

These binoculars have good optics and give you a good, clean picture with ample, distortion-free light. The focus is solid and stays where positioned and the rubberized coating provides for a solid, comfortable grip. The only downside to these binoculars is that they are heavy. If you're used to more compact or lightweight units, you will definitely notice the difference and they could present fatigue through extended use. If you're doing just a little day-trekking with minimal supplies, the weight may not be an issue, but if you're carrying more of a full pack (24 hours get back home bag), you're likely not going to like the weight of these and they would better serve as a vehicle or home binoculars. The advertised specs of 12x50 appear to be accurate and they come with a well-padded bag (including a shoulder strap) and a dedicated neck strap for the binoculars.
