    Best Binos On the WaterBest binos on the water. Auto focus works great. Saw a fledgling osprey from a shoreline nest suddenly learning to fly. Could not have been more pleased with the ability to quickly focus clearly on the subject and follow it around. All while driving a boat solo bouncing on the water. Worth every dollar.

    Steiner, Steiner, Steiner….I live on a hilltop and if someone burns a pile of cedar, these binoculars allow me to get a better look and it’s risk to my property. They are heavy, and steady in your hands. The quality of the glasses are just what you’d expect from a German firm. You just cannot go wrong with a quality product like this one.

  3. Dave

    Great product and a good value.While Steiner has always produced quality optics, I find the auto focus feature on this unit makes using the binoculars much easier to use than the old school, dial to focus units. Tossed my older optics after experiencing these. Bright, light and easy to use when on the water or on land. A good value too! No need to spend more unless you need additional features such as range finding or an integrated compass.

    amazing , truly amazing.the first time I looked through these superb binoculars it was a completely new experience. so clear and sharp and bright. I’ve bought some nice glass through the years but nothing like this. the price is so worth it. with the legacy warranty and the quality of these why would you buy anything else?


    Best binoculars I have ever ownedThe clarity is outstanding. It stays in focus from about 20 yds to infinity. Great field of view. They are a bit heavy but has the feel of quality. Great in low light situations as well.

    Good ValueI don’t have a lot of experience comparing these to other marine binos, but i can compare them to other hunting binos like the 10×42 Bushnell Trophy (~$100) I bot for elk hunting. Those are roof prism vs these Bushnells (like most marine) are porro prism.This summer I pledge to take them both on the boat and test them side by side for clarity, although not really fair compairng $100 vs $300 optics. The $ are n the glass, and while neither is high end item both are excellent value.Interesting that I do find the Bushnell’s better at color definition when hunting vs the Steiners on the water, but that might be just me projecting. To really compare side by side I would have the take the Steiner’s elk hunting and that’s not going to happen due to weight. Maybe I will try a side by side in CO when glassing this year in Oct.I use these while fishing LI Sound mostly to see other boats, bunker balls and shore features.I fish a 22″ Grady. If I had a bigger boat or ran Charters I would prob step up to the Navigator or Commander Series after checking them out,. But as I found out through research on hunting bino’s and spotting scopes, every step up in price brings an increase in quality, but at a decreased rate.The $300 I paid for these is definitely worth it over the $100 cheap set I lost overboard, and the various small binos’ and monoculars I was using in 2018,Very good entry level marine choice. They are all the bino I need on LI sound considering wave action is not ocean level, always in sight of shore and nice clarity out to 500 yards is the primary use. Not to say they don’t do a good job at long range for 7×50, but it’s tough on a boat that is pitching in 3′ ft chop to get more than a glimpse without risking a headache.Low light (early morn and dusk) they are excellent. The 50mm objective lens is great for these situations.I like the glass, and although had only one season they took a normal boat beating – being dropped, salt water on len’s and body, etc. I expect them to last years.If you are looking for a good marine bino I highly recoomend these for the $. Unless you have a specific need to more magnification, 7×50 is a great choice for on the water use as any higher and you will have trouble fixing on target and keeping without excellent hand eye coordination and risk of a quick head and eye ache.

    AverageI bought these at the same time as a Steiner 7×50 Commander XP model. The Commander XP’s use the same case but for triple the price have better eyepieces, coatings and optical specifications and a few additional or better accessories than the Marine model.I compared them in terrestrial and celestial viewing but the easiest comparison is done with astronomical subjects since they really define performance clearly. The images in the Marine model merged effortless. In the Commander XP, I have difficulty merging the images. The XP’s are obviously badly out of collimation. I don’t care to fix this myself on binos in this price range but I was pleased that the much less costly Marine’s appear to be flawless in this respect.I evaluated the real and apparent fields of view as well as the sharpness near the edge of the field.In the Marine model, the real field of view is reasonably wide but apparent field is quite narrow. It’s not bad but it’s not a spectacular vista either. In the Commander XP, the real FOV is only barely perceptibly wider. Steiner’s website lists the specifications. The apparent field, which is not specified is about the same for both. The almost indiscernable extra width of real FOV does not contribute much to the value of the XP’s for triple the price.On the Marine model, I put Sirius and Jupiter in the center of the field. They each looked nice. Moving the binoculars so that the objects were farther from the center of the field I could see the image degraded about half-way to the edge of the field of view. Near the very edge, the image was appalling. Much more than half-way out of the center of the field of view, the star or planet turns from a bright point to just a smear. Near the very edge it’s a dim smudge. I tried the same with the Commander XP. It was every bit as bad. I could have probably improved things a little by refocusing but that only means that the field isn’t flat either.Are the XP’s better on dim objects? The optics are supposed to transmit 96% light compared to the Commander V’s 95% and the Marine’s 90%. I saw very little difference on dim objects like the Orion nebula or the background of the Pleides or Jupiter’s moons. Again, I can’t see the justification for triple the price, so I commend these Marine models over their far more costly cousins.Both have generious eye-relief, 20mm for the Marine and 22mm for these XP’s. They also have the same weight and dimensions. They’re heavy but still reasonable if you’re wearing a thick coat to pad your chest and a harness to keep them from swinging all over if you’re moving. Also, at 7x they’re reasonable for handholding. For me, 7×50 is about the limit for handholding. Heavier or higher power would be too shakey. 6×56 might be nicer if they were more common.Where the XP is clearly better is with small details like the click-loc strap attachments (for use with Steiner straps and harnesses only), the better eyepiece covers, lens covers, focuser grips, shading eye-cups, and various doo-dads that come in the case. It comes with a flotation strap which the Marine doesn’t, but I would still rather prefer a harness which neither comes with.I bought these Porro prism binos because I thought for the high price, particularly the XP’s, they should be outstanding. While roof prism binos might require fifteen hundred dollars or more to achieve optical exellence (or so I’ve heard), it should be easier with porros. With these, the optical quality is lacking nontheless. To be honest, I have nothing to compare them to. I’ve never seen better, but I was still totally underwhelmed by the performance which was only slightly better than I would expect from binoculars in the hundred dollar range. In the case of the XP’s, it’s a rip-off, no question. In the case of the Marine model, the value is closer to reasonable because of the far lower price. I didn’t compare them to other binos in their price range. The Fujinon line would be the most similar but it would also be worthwhile to compare Nikons, even the well-regarded Monarch roof prism models which are in this price category but are totally different.

    Excellent!I’ve tried several brands – Steiner is the BEST. These binoculars have a larger “sweet spot” for your eyes so you see the target without having to hold them so carefully centered. This makes them so comfortable and easy to use. And yes, the optics are exact – giving almost a 3D sense of the scene. Don’t use the phrase “night vision” because these only marginally increase the amount of light in dim situations. I bought a second pair for the RV because they’re so easy to use with great results.
