Barska Gladiator Binoculars Review
This Gladiator 7-21X40 variable binocular has Barska’s Ruby UV Lenses Technology, shock-absorbing armor, and multi-coated BK7 prism glass optics.
The Gladiator has lots of reviewers online that have rated the variable optic with an above average rating.
Since most people like “big”, I initially wanted to feature the beastly 10-30X60 model, but that’s more on the spotting scope end of things. So, I went with the 7-21X40 for long range hunters that might appreciate the variable zoom ability.
For your benefit, here’s the Q&A if you’re ready to see what makes the Gladiator a powerful hunting ally.
- Zoom power
- Tripod adaptable
- Ruby lenses
- Shock-absorbing armor
- Short eye relief
- Not weatherproof
Gladiator 7-21X40 Binocular Q&A:
This is Barska’s ruby coating that helps to minimize UV glare when glassing in bright conditions.
It will also help with the overall reduction of reflections and haze to improve light transmission. Less glare equals better clarity and brightness.
But, just be aware that the image tone is going to be a little different because of the tint. Often times, the ruby coatings on low budget binos can filter out certain colors to enhance wildlife and reduce haze and foliage tones and reflections.
With such a high range of zooming capability on this bino, Barska implemented a user-friendly zoom lever. Although Barska calls it a “zoom thumb lever”, it’s more like a “zoom index finger lever”. Makes more sense right?
Just hold your binocular as you would in the correct position and use your index finger to put pressure on the lever to bring it down to increase the zoom power.
BK7 prism glass is used for its reflectivity abilities to allow light to produce an image for you when you look through the binocular. Although BAK4 prism glass is generally superior to BK7, the refractive index rate of BK7 isn’t that much behind the BAK4s.
But, there is a tell-tale of the BK7 glass that might be of consequence when you’re zooming in on such high ranges.
The squarish exit pupil and the grey caps or edge distortion when looking through the bino might be enhanced as you increase magnification. But, it’s also what helps to keep this binocular in the low price range of around $40.
Unfortunately, there isn’t. One of the unique features of the entire Gladiator series is the variable zoom feature.
This 7-21X40 is actually the lowest power of the entire line. There’s also the 8-24X50, 9-27X25, 10-30X50, 10-30X60, and the monstrous 12-60X70.
Most of these, including the 7-21X40, all vary in the very low $40ish price range.
- Ruby UV Lenses for glare and reflection reduction
- BK7 prism glass and multi-coated optics for bright and clear image quality
- 7-21X variable zoom power for extended long range hunting
- Shock absorbing rubber armor for ultimate binocular protection
- Zoom lever for easy and smooth magnification transitions
- Backed by Barska’s Limited Lifetime Warranty
Our Verdict on the Gladiator Binoculars
To glass it up, the Barska Gladiator 7-21X40 binoculars are a cheap buy. If you’re wanting to spend as little as possible for a range of features, this is it. However, if you wear specs, you’re going to be on the short end of the stick. It’s also not weatherproof so that might be an issue if you’re not ready to call it a day when those clouds come a-rollin’ in.
If you’re not sold on the zoom capabilities of the Gladiator, but you definitely want a high powered optic, consider the Barska X-Trail 15×70 binocular. It’s still very cheap, and you’re getting some freebies thrown in with the bino buy!
There aren’t many manufacturers that dabble in the zoom bino market, but we did find one. The Simmons ProSport Compact binocular is small in size with zoom power from 8-17X. Better yet, it’s super affordable. Just skip your daily fast food buy and opt for a Simmons – great deal!
The Barska Gladiator series is your family zoom line. If you want to go bigger, there’s always more punch from Barska. You can trust on them to offer variety that no one else can match!
