Steiner Military M2080 20×80 Porro Prism Binocular Review

Let’s Dive into Steiner Military M2080 20×80 Porro Prism Binocular

The Steiner Military M2080 20×80 Porro Prism Binocular is a powerhouse optic designed for serious observation. Manufactured by Steiner, this binocular combines massive 80mm objective lenses with 20x magnification, offering exceptional light gathering and detailed viewing at long distances. Built to military standards, it promises durability and reliability in demanding environments.

As a seasoned outdoor and tactical gear specialist, I was drawn to the M2080 by the need for a high-powered binocular capable of delivering exceptional clarity and range. I needed a reliable optic for long-range observation during search and rescue operations, and for identifying wildlife at extreme distances. The promise of Steiner’s renowned optical quality and rugged construction made it a compelling choice.

Unboxing the Steiner Military M2080, my initial impression was one of substantial quality. The weight, while significant at over four pounds, felt reassuringly solid. The olive drab green rubber armoring provided a secure grip and immediately communicated a sense of durability.

Compared to other high-powered binoculars I’ve used, like the Nikon Monarch 5 20×56, the Steiner stood out with its larger objective lenses and more robust construction. I chose the Steiner primarily for its superior light-gathering capabilities, crucial for low-light conditions. The Nikon, while excellent in its own right, couldn’t match the Steiner’s low-light performance.

I was immediately impressed and excited. The size and weight were expected, but the clarity and brightness of the image were immediately apparent even before taking them out into the field. I anticipated a significant step up in performance over my existing optics, and the Steiner Military M2080 appeared ready to deliver.

Real-World Testing: Putting Steiner Military M2080 20×80 Porro Prism Binocular to the Test

First Use Experience

My first field test of the Steiner Military M2080 took place during a search and rescue training exercise in the mountainous terrain of the Pacific Northwest. I needed to scan vast areas for potential subjects. The conditions were challenging, with intermittent rain and low-hanging clouds.

The Steiner performed admirably, providing bright, clear images despite the poor weather. Its waterproof construction instilled confidence, and the rubber armoring provided a secure grip even when wet. The large objective lenses gathered ample light, allowing me to spot details that would have been missed with lesser binoculars.

The Sports-Auto Focus System took a little getting used to, but once adjusted to my eyesight, it provided consistently sharp images from a reasonable distance. Initially, the weight was noticeable, and a tripod became essential for stable viewing over extended periods. I was also slightly surprised by the relatively close minimum focus distance of nearly 200 feet.

Extended Use & Reliability

After several months of consistent use, the Steiner Military M2080 has proven to be a reliable and durable optic. It’s been used extensively in varied environments, from coastal monitoring to desert scouting. The binoculars have held up incredibly well.

Despite being subjected to bumps, scratches, and exposure to the elements, the rubber armoring shows minimal wear. The optics remain crystal clear and properly aligned. Cleaning is relatively straightforward, requiring only a soft cloth and lens cleaner.

Compared to my previous binoculars, the Steiner offers a superior viewing experience in terms of clarity, brightness, and overall image quality. The ruggedness and reliability have also been exceptional. It significantly outperforms other binoculars I’ve used.
