The Review

Optics… Everyone should have some at home, the car, EDC and bug-out bag. Whether you are trekking down an off-beaten path or dealing with a bug-out situation, it is a huge tactical advantage to be able to have a view from afar. While some prefer binoculars, I prefer the compact size and light-weight of a monocular. In this article, we’ll be taking a look at Alpen’s Sport 8×25 waterproof monocular.

Established in 1997, ALPEN Optics set out to to provide high-quality optical products at affordable prices. Today they offer sporting enthusiasts a wide-variety of binoculars, spotting scopes, rifle scopes and accessories. All Alpen brand products are backed by a fully transferable Lifetime No Fault Warranty against manufacturing defects, materials and workmanship.

Alpen Model 120Measuring only 4.75 inches long and weighing just over 5.5 ounces with the strap and lens cover, ALPEN’s model 120 monocular housing is both waterproof and fogproof, and designed to endure the toughest of conditions. It is encapsulated in a compact, lightweight and extremely durable and ergonomic rubberized grip ideal for use in wet weather. Model 120 is also constructed with smaller prisms and objective lenses further reducing its size and weight.

Simply put, a monocular is really just a modified refracting telescope used to view objects at a distance as though they were much closer. In addition to a series of objective lenses used to magnify the image of distant objects, a monocular utilizes a pair of prisms to fold the optical path thereby reducing its overall size and weight. However, in contrast to most telescopes where the image is inverted, by utilizing a pair of prisms the resulting image appears in the correct orientation.

ALPEN’s model 120 combines a powerful 8x magnification with a 25mm objective lens to provide a long eye relief of 18mm for eyeglass wearers, an exit pupil diameter of 4mm and a 321 foot field of view at 1000 yards with a close focus distance 12 feet. Its BaK-4 high index glass and multicoated optics provide superior brightness, resolution, and edge clarity regardless of your subject for outstanding optical performance.

Monocular settings are typically pretty simple, and ALPEN’s model 120 is no different. To set the eye relief which is the distance between the eyecup and the lens, simply twist the eyecup to one of three clickable settings. Focusing this monocular is performed by twisting the notched focus-ring located just behind the eyecup until the focus is clear and sharp.

The nylon carrying case is really nothing special. It is a simple, lightweight case weighing only 1.1 ounces. It has a hook and loop closure and sewn-on belt loop capable of holding a belt up to 1-3/4″ wide.

The eyecup is protected by a tethered rubberized cap that is easy to remove if necessary. There is also a 7″ fixed nylon lanyard provided for tethering the monocular to your wrist.


Final Thoughts

Small enough to fit in your pocket or hung around your neck, ALPEN’s model 120 monocular is ideal for hiking, birding, sporting events and any other on-the-go activities that require a telescopic view. Perfect for survivalists and outdoor enthusiasts alike, ALPEN packed all of the quality, performance and value that you would expect from any good optic into its small, lightweight footprint.

I carry this monocular in my EDC so its always at my side wherever I go. I use it whenever I’m at the park with my dogs and want to check out the local wildlife, at concerts and sporting events, at the shooting range, and everywhere else that I need to see from a distance.

ALPEN’s high-quality optics and weatherproof design offer enthusiasts an affordable alternative, comparable to competitors costing several times as much. At a little over $50, you really can’t go wrong with this optic. If you are shopping for an affordable monocular, this one definitely should be on the short list.
