Reviews & Ratings for Barska Gladiator 25-125x80mm Porro Prism Zoom Binoculars — 9 reviews — Page 1

I am very disappointed with the quality of these binoculars.
My unit has a serious double-vision/collimation problem. I tried adjusting the collimation screws many times. It is possible to temporarily align the two images, but the adjustment does not remain stable. After moving or changing the angle of the binoculars, the images become misaligned again. No matter how much time I spent trying to correct it, I could not achieve stable collimation.
At 25x magnification, the binoculars actually produce a good, sharp image. Around 50x they are still somewhat usable. However, as the magnification increases beyond that, the image quality deteriorates significantly. At 100–125x, the image becomes difficult to use comfortably, and the zoom mechanism itself leaves a lot to be desired.
The double image also causes significant eye strain because my eyes constantly try to compensate for the misalignment.
I bought this model specifically because of its large 25–125x zoom range, but in my experience, the high magnification simply does not justify buying this binocular.
If you are considering this model specifically for the 100–125x capability, I would not recommend it. At 25x the image can be very good, but that defeats the main reason for buying such a large zoom binocular.
Unfortunately, the overall quality and especially the stability of the optical alignment have been very disappointing.

125 magnification is a sales hype. It is there but you to fiddle allot to get it. Zoom is a misleading term.Zoom should be understood to mean variable magnification.When you increase magnification you lose field of view and light.That is just a fact in binocular optics. The Barska 25-125x80 that I own are good to 55x after that you I have to start fiddling with focus issues. The optics are clear and sharp to 115x, once in focus.A point I would like to make is this. You will not find a 25x80, barska makes 30x, you can buy a 40x for $3000, you want 50x, not in a binocular. Imagine looking through a fixed mag. binocular, and seeing something of interest,and wishing you dad more power. Well with these you have it at your finger tips.These are well worth having.
Pros: Access to variable magnification.
Cons: Magnification indicator hard to see.

Can't even get the two lenses blended together to where it looks like one circle.

Great buy for the money

It's a really cool binocular. I can change the magnifications at will. And it works really good too. Kind of difficult to figure out and use, but once you get the process started, you just keep rollin' with it. Reccomened. Just also make sure you can handle the weight.

For the price it is a good purchase.
Pros: High Power
Cons: With all high power optics a stable rest is needed

From the hills of Fort Tryon, NYC, looking at St. Peters College across the Hudson, it was like I was standing inches from the balcony of the college. WOW. And I was able to see an eagle (or was it a crow) perched in the vicinity of the college. From so far away yet I was so close there.
