MM830 Military-Marine 8x30 is rated 4.8 out of 5 by 52.
Rated 5 out of 5 by from Fine optics in medium size Purchased Marine 8x30s at West Marine for work and sports viewing. Now I know what I've been missing using lesser glass. The light transmission and field of view really make a difference versus what I had been using. The sports focus is fantastic. Set it and forget it. Everyone who tries them can't believe the clarity. Overall a wonderful product at a reasonable price. Will not be my only pair of Steiners.

Rated 5 out of 5 by from War-zone proven Bought a pair of these in 2004 for a deployment to Iraq. They got knocked around for 11 months of HUMVEE patrols from Najaf to Baghdad, and are still working fine a decade later. I still keep them in my car, and last week used them for stargazing at the confluence of Venus, Jupiter and Mars with my wife - a much more enjoyable activity than their original purpose.

Rated 3 out of 5 by from Very crisp optics, but not waterproof with age I recieved my binoculars used from a family member and the optics are very crisp and they seem very well made. However, as soon as I had them in the rain, both eyepieces seeped water and now the binoculars are unusable. Granted, these were manufactured in 1997, but I thought they would hold up better than this. I'm going to put the Heritage warranty to the test hopefully get them fixed.

Rated 5 out of 5 by from Crazy warranty I found a pair of Steiner 8X30 Military/Marine binocs while hunting deer on Kodiak Island Alaska recently. They were barely visible in the mud. I pried them out and had to jerk on the strap to dislodge it. They were there a while. I joked to my hunting partner that someone might be back for them and hung them in a tree for the rightful owner. Not sure the owner had survived the loss as there were clearly bear tooth marks on them. Really didn't think much about it until back at camp that night when a fellow hunter said "they probably would replace those". Shoot, I had abandoned them out there somewhere. Well couple days later with no effort to look for them I stumbled upon the tree I had hung them in so now I was the rightful owner I guess. I grabbed them. Upon further encouragement I looked into service. They were beyond hope with water in optics... I sent them in and about 10 days later with no questions got a brand new pair sent to me. To same I am pleased would be a pitiful understatement. Merry Christmas to me!!! Thanks Steiner. You rock.

Rated 5 out of 5 by from Steiner the bar all other companies shot for! From the durable finish to the "as advertised" auto focus these binoculars are top of the line. If you're looking for a great set of binoculars to use for hunting, fishing, or other activity, look no further. Crystal clear viewing at its finest, and at only 18 ounces you won't even notice them in your pocket or around your neck.

Rated 5 out of 5 by from I was skeptical at first when I saw these at the 2 I was skeptical at first when I saw these at the 2015 SHOT Show in Las Vegas this year, after looking at all of the binocular manufactures at the show I was met by a representative within the Steiner booth and was shown these inexpensive 8X30’s. I was looking for a decent pair of binoculars that I could use for my travels to Thailand and how happy I am that I bought these. When you first try to demonstrate these 8X30’s within a small area such as a large retail store with poor indoor lighting I don’t think that you’ll be too impressed. You won’t get the full advantage of them until you adjust them from a braced position outdoors to enjoy the full potential of these Steiner’s. All of my friends were trying to get me to purchase other manufacture’s binoculars that were in the $300 - $400 price range. For the price you can’t go wrong, and not having to adjust the focus is a big plus in my opinion, well worth the money.

Rated 5 out of 5 by from Best investment I've always wanted a pair of Steiner optics but they were always out of my price range. Found a pair of 8x30 military marine binoculars at a store closing. The difference in quality is instantly recognizable. Compared my old set side by side with the Steiner's, there was no comparison! The image quality and brightness blew my old set out of the water. I can't beleive I went all these years without buying a quality set. I'll never go back to cheap optics again

Rated 4 out of 5 by from I am very happy with the MM830. The product is exactly what I needed and expected. I have been wanting the MM830 for some time and the opportunity presented itself through a Canadian Retailer at a great price. My eyesight at 65 varies from one eye to the other and chasing game with my old focus as you go binos was a bother. The only drawback was to register my unit on a Canadian/US application that requires a US Retailer address in order to proceed. So I couldn't Register for ongoing product updates Etc. All in all, I am very happy.
