Let’s look at some of the specifications given, it’s confusing

The description mentions a 30x magnification for the optics while specifying a field of view of 126 m / 1000 m (369 ft / 1000 yards). ?????

This is actually contradictory since such a field of view is typical for a magnification of 8x.

Regarding the BAK4 Prism mentioned in the product description. I need to get my hands on of those binoculars to check that out.

As for Fully Coated Optics? The Ruby coating as seen in one of the product images filters out red components of the light, this how however reduces the overall brightness of the images and worse produces a false-color image.

I also don’t see a 60 mm objective lens as listed in the specification??  The exit pupil is mentioned with 2.5mm.

As the formula for the exit pupil is:  EP = DObjective / M, and we have figured out that the magnification is 8x, then the Objective lens must be 20mm, which makes much more sense in compact binoculars.

As you have seen, you must read the specification carefully and analyze them as sometimes they make no sense.

Weight and Portability

These models are light and compact thus users will not have any problems toting the binoculars around. It weighs only 7 ounces/ 200 grams and this even includes the carry case. It also includes a neck strap so you won’t have to carry it by hand and instead, let it hang around your neck if not in use.

In terms of storage, the whole package includes a storage case plus a cleaning cloth to maintain the spotlessness of the binoculars. The addition of a storage case will keep the unit free from dirt build-up, nicks, and abrasions and after each use, you can wipe the binoculars clean with the handy cloth.

Are Cheap Binoculars Worth it?

Those are very cheap binoculars. It’s not waterproof and not fog proof.  Some very cheap binoculars give of strong plastic smell for quite a while when unpacked.

Low-priced binoculars can forego several important aspects that make advanced binoculars effective. For the price, you can not expect much of optical performance. Good optical glass and good coatings, which are the main cost factors in binoculars that perform better can not be produced at such low cost.

If you need a cheap pair of binoculars and you do not need the advantages that real binoculars provide, you may appreciate the workings of these instruments for a while, however, better buy some good binoculars in the first place.
