Nikon 7239 overview

  • 1Description

Optimized for comfortable viewing on the water, the Nikon 7x50 Action Extreme ATB Binocular is an ideal optic for boaters who often find themselves on rough or rolling seas. With an exceptionally wide exit pupil, users will enjoy seeing the entire scene laid out before them with the movement of the horizon line greatly minimized, plus its long eye relief provides room to back off the eyepieces for a more comfortable viewing position. These design features help mitigate the disorientation and discomfort often experienced when looking through optical devices on the water. The traditional Porro prism design, when combined with the over-sized objective lenses, BAK4 prism glass, and anti-reflection fully multi-coated optics, delivers immersive high-contrast views that are bright and sharp, with accurate colors and a rich depth of field so users can differentiate the relative distance between objects in the view. For hunters, birders, and outdoor enthusiasts, the large exit pupil and large objectives make the Action Extreme perfect for scanning and identifying game at dawn and dusk, or under heavy canopies.

Complementing this optical performance are design details that allow the Action Extreme to withstand the rigors of outdoor life. The Porro prism design has an inherently balanced and comfortable feel in the hand for long-duration observation sessions, and the chassis is wrapped in a rubber armor that provides a sure and reliable grip in cold and wet weather. Its optical tubes are nitrogen filled and O-ring sealed to be waterproof, and resistant to internal fogging when moving through extreme temperature and environmental conditions. For hands-free use, the binocular is tripod mountable to eliminate arm fatigue and greatly reduce vibrations. A tethered one-piece ocular rainguard covers the eyecups as they hang around the neck and prevents rain and spraying water from filling them, and the objective lens caps can clip onto the neck strap to keep them safe from blowing overboard or being lost on the forest floor.

From the trail, to the range, to the boat, the 7x50 Action Extreme binocular is engineered to deliver the performance required by discerning observers—especially boaters and outdoor enthusiasts who won't let inclement weather and rough seas keep them at home or in a safe harbor.

Optical Performance
  • 7x power provides moderate magnification while helping to produce a wide exit pupil for enhanced low-light use
  • Large 50mm objective lenses provide improved low-light performance versus smaller-objective models, ensuring images are bright even in challenging conditions

Nikon 7239 reviews

7x50 Action Extreme ATB Binocular is rated 4.6 out of 5 by 18.
Rated 3 out of 5 by from Good binoculars at a great price. Nikon's action extreme 7x50's offer a clear, bright picture at a fraction of the cost of more compact roof-prism binoculars. The porro prisms offer several advantages. 1. they are more comfortable to hold IMO. 2. they are a better value optically, and 3. they offer greater depth-of-field. What you won't find in these binoculars is the kind of edge sharpness that you find in binos costing 4 to 18 times as much money. They suffer from no other optical problems. Chromatic abberation is low, the field is relatively flat and does not suffer from the rolling-ball effect. They are pleasant to hold - though I have big hands, the 7x35 model might be better for those with smaller hands.

Rated 5 out of 5 by from WOW!! Got these as a Birthday/Mother's Day gift... They are spectacular! Up on the deck of our mountain cabin, I can not only see birds in the trees but with the light that these binoculars gather it allows me to see things back up under the trees in the shady areas. The images are so clear and they look as though they're so close that I can reach out and touch them. Honestly, you can see not only color clearly but also the details of what ever you're viewing. Bright sunny days or even overcast and low light days. I'd recommend these and have with no misgivings, they're great! I'm thinking though that I'm gonna have to break down and get my husband a pair, every time I go to look for them he's using them :o)

Rated 5 out of 5 by from Fantastic bino Used for observing sailing regattas and other maritime activity. Very comprehensive and easy to execute fine adjustments for focusing, with and without glasses. The image provided is bright and therefore easy on the eye when used over a long period.

Rated 5 out of 5 by from WOW! I need to say that this was my first pair of binoculars ever. I did one heck of a lot of research to find ones that would be good for stargazing. A little nervously, I brought them back to my apartment here in downtown manhattan. There was a lightening storm, naturally. But you know what? I can still see dozens of stars, even through all of that! I am so incredibly pleased. People complain about the weight, but it feels like almost nothing to me. if you're looking for something for stargazing, this is great. One thing which I kept seeing was that 10x binos were not necessarily good for stargazing because the minute hand motion would quickly prove annoying. Seeing a 7x, I undersand exactly what they meant. Don't get the 10x, go for a lower magnification, honest to goodness. Also, I wear glasses and and so overjoyed that they adjusted so that I can use them without, although it is equally excellent with them on. Cons- it doesn't come with a free tablet? Actually, the only drawback is that this model does not have a built in tripod mount, so if you want to stick it on a tripod, you need to buy the add-on mount as well as the tripod. But it's lightweight enough that that really isn't a big problem for me.

Rated 4 out of 5 by from Didn't impress me like other Nikons I picked these up in addition to my other Nikons because I didn't have a 50mm pair to search for owls yet and wanted to get into more twilight viewing. Being an optics freak and an avid birder, I know that a 7 x 50mm bino will give me a HUGE 7+mm exit pupil and a great twilight factor so they should be far brighter than anything else I have and would allow me to see owls as they come out around dusk. I knew before ordering that they would be big and bulky, but I'm 6'1 tall and 200lbs so I didn't really care about the weight, I just wanted a super bright pair of binocs. I knew the field of view wouldn't be fantastic and I'd be loosing a touch of sharpness as well from my other pairs, but to me it was worth the tradeoff for a super bright image at the cost they were charging. The thing is, I took all three pairs of my full size Nikons out to compare them to see how much brighter the 7x50's were, and I realized that I could discern no difference in brightness even in dusk conditions when my pupils were dialating. I suspected that the coatings were better on my more expensive pairs, but I thought I'd still see a difference, but didn't. Then all the sudden the quite narrow FOV started getting to me. You really can't find birds very easily with these even though they are only 7x because it's a bit like looking through a cardboard tube. The sharpness is also not on par with the Monarchs or above. When they say multi-coated optics, they don't mean all of them! They mean just the objectives and/or the eyepieces. Fully multi-coated is a whole other level where every piece of glass is multi coated on both sides. If you are used to Tasco, most entry Bushnells, or have never spent more than $60 on a pair of binocs, you will be impressed since they are still better than what most people are looking through. But if you're like me, then look up the line further. That being said, I think that you can't ask for a lot at the price these go for, and I think you are probably getting a good value. I am an optics snob unfortunately and couldn't accept the compromises in performance. Optical performance - 3 stars, Value for your dollar - 5 stars, hence my 4 star rating. If you are using them on a boat, I wouldn't hesitate, these should satisfy. Dedicated birders, save your pennies for something better! Hope this helps!

Rated 5 out of 5 by from Great Buy Cant go wrong with these, great quality at a good price. 7x50 are a good choice if your hands shake a bit. If you have a firm grasp the 10x50 might be fine. BH shipped them in 4 hours :)

Rated 5 out of 5 by from Perfect for tennis at Arthur Ashe Excellent optics, nice magnification. Loved using them - very comfortable. Only negative is the suggested way to hold the lens caps and eyepiece cover doesn't work well: these tend to fall off, so if you're in a sports event you may lose them. In our case luckily we recovered the eyepiece cover that fell off. Just put the covers in the case the binoculars came in, which you have to carry separately in a bag. Otherwise an excellent purchase.
