Marine 7x50 is rated 4.8333 out of 5 by 6.
Rated 5 out of 5 by from Great for Maritime Enforcement In short, these are great optics for maritime enforcement in the urban/marina environment, even in low light conditions. I was also pleased that I could simply put a NV monoscope up to one of the eye pieces or a cell phone camera against it to capture images. I have no problem acquiring vehicle plates and vessel hull numbers in low light at medium distance, sometimes even when targets are in motion. I had an issue with one of the diopters not adjusting properly a few months after I purchased these binos and simply sent them in for service. The turn-around time was reasonable. I will never buy another pair of manual focus binos.

Rated 5 out of 5 by from A great binocular that can be used for many things I wanted a good binocular that was waterproof, fog free, great optics at a fair price. My wife and I like that we can take the binoculars kayaking, hiking, or for bird watching. The Marine 7x50 is like the SUV of binoculars.

Do you know how to change the battery in a Steiner Military Marine Pilot 7x50?

Asked by: Jesse07
Next to the right objective lens there will be a flat head screw driver battery cap. You can unthread it to access the battery.

The description says this binocular is waterproof. How waterproof is it? Will it survive if it falls over the side of a boat with a float strap attached?

Asked by: Aquaman
The Marine 7x50's are waterproof in that they will resist rain, ocean spray, and potentially brief, shallow submersions. If submersion is a serious concern, I would highly recommend the Navigator's

Some of the websites that sell this product (got the link to them from this site) said this set of binoculars are nitrogen purged, but I don't see it say anything about that here. So are they?

Asked by: Tcup
All Steiner Binoculars are nitrogen purged.

What material is the core (chassis) of marine 7x50 are they plastic?? metal?? I saw "how its made" and the chassis looked to be plastic.

Asked by: newone
The term 'Plastic' covers a wide range of malleable solid materials. Steiner binoculars are made from a durable polycarbonate plastic called Makrolon, which is similar to what automotive headlights are made from. They are built to withstand 11 G's of impact force and coated in protective NBR rubber armor
