Welcome to my review of the Ohuhu 8×40 Dual Focus Monocular. This optic is advertised for people who want something they can use for sporting events, birdwatching, hunting, camping, fishing, and traveling, and it’s a very inexpensive option. Let’s see how well it stacks up.
This variety is six inches long, and features a 40mm objective lens. It’s extremely lightweight, at just 8.5 ounces, and offers a field of view that’s 213 feet wide from 875 yards. Eye relief is unspecified, but I’d estimate it to be a comfortable 12mm to 14mm.
What Do I Get For My Money?
Ohuhu includes all the various accessories you’d expect to get with a new monocular. You’ll find everything you need for basic use in birdwatching, eyeballing game, or watching your favorite baseball team make their way around the diamond. This is what you’ll find inside the box:
- The Ohuhu 8×40 Dual Focus Monocular
- A carrying pouch
- A lanyard
- A cleaning cloth
- Instruction manual
The lanyard is decent enough, basic but functional, and the pouch provides adequate protection of your modest investment. The carrying case closes with the standard hook and loop fastening system, and it includes a belt loop for securing the accessory to your clothing. Unfortunately, the case is made from rather flimsy nylon, but it seems okay as long as you don’t abuse it. The real downside in what’s included is what’s absent – lens caps.
How Powerful Is This Glass?
This optic features a 40mm objective lens, which will give you basic 8X magnification. I’ve seen more powerful monoculars in this size, but the problem with getting more magnification in such a lightweight device is hand shake; there isn’t much problem with that here. The dual focus mechanisms allow you to adjust your image from either the front or rear rings, meaning the glass is simple to use one-handed. The magnified image has plenty of sharpness and clarity, but you may notice a bit of blue color fringe around the perimeter of your view.
Field of view, as previously elaborated on, is quite generous and offers you plenty of viewing range to find your subject. Sure, I’ve seen better, but I’ve also seen glass with a whole lot worse sight capabilities.
What Type of Optics Will I Find In The Ohuhu 8×40 Dual Focus Monocular?
Ohuhu skimped on the optics, but they still do their job. You’ll find the basic BK–7 roof prism inside the glass, with multicoated optics. I wish Ohuhu had used BaK–4 prisms instead, and fully multicoated the optical surfaces, but images viewed through the device still have plenty of detail, brightness, and contrast.
The dual focus rings, one at the front of the monocular and one at the rear, offer plenty of stiffness to prevent you from inadvertently bumping your image’s clarity off, but they both still turn smoothly and easily enough to be operated with just a single hand.
The downside to the inexpensive optics used within the Ohuhu monocular is chromatic aberration, the blue color fringing I notced early.
What’s the Body Like On This Model?
Ohuhu has built their monocular to last, surprisingly enough. It’s compact and easy to handle, with a rubber exterior that makes it easy to grip even when you’re operating it with just one hand. There is great protection against bumps and falls, but one aspect of protecting the glass is missing – lens caps.
Alas, such an inexpensive monocular doesn’t include a tripod mount. It would be nice to have, but this glass is low-powered enough that it isn’t absolutely necessary.
How Durable Is the Device?
The Ohuhu 8×40 Dual Focus Monocular is both fogproof and waterproof, meaning you can use the glass in harsh weather conditions without any concerns. Yes, the optical chamber is nitrogen-purged, and the lenses are sealed with O-rings. As far as impact resistance, the rubber exterior does a fine job, and my glass has survived several drops without any noticeable problems. You just have to be careful with the lenses, since there aren’t caps provided.
How Well Does This Monocular Work in the Field?
I’ve used the Ohuhu 8×40 Dual Focus Monocular for both birdwatching and spotting game when hunting. While it’s not the most powerful monocular you can get, it’s still a fine choice for closer range viewing. It’s great for a survivalist’s bag, or to just carry along into the field or to a ball game.
Ohuhu 8×40 Dual Focus Monocular Summary
Thanks for stopping by and checking out my thoughts on Ohuhu’s 8×40 Dual Focus Monocular. This basic, budget-friendly model offers a terrific image for the price, and is an excellent value. Unfortunately, there’s no lens caps or tripod mount, and the blue color fringing around the edge of your view is mildly annoying.
