Have you ever wondered what the most powerful binoculars in the world are?

Well, I did, so I did some extensive research to find out more about the most powerful binoculars in the world and found three pairs of binoculars, which are serious contenders.

Based on strength, these are the three most powerful ones:

  1. Sunagor 30-160×70 ($ 399,99)
  2. Oberwerk BT-100-45 (Not available)
  3. Oberwerk BT-100XL-SD ($2750)

Two manufacturers produce these extremely powerful binoculars:

  • Oberwerk
  • Sunagor


Kevin Busarow founded Oberwerk in 1991 and was initially a software development company.

After many years of developing software, the owner decided to change the direction of the company and focus on designing binoculars.

Throughout the years, the company has designed and produced many different binoculars, but in this article, we will only be discussing the two most powerful ones:

  • Oberwerk BT-100-45 (discontinued)
  • Oberwerk BT-100XL-SD Binocular Telescope

Oberwerk BT-100-45 (discontinued)

For many years the Oberwerk BT-100-45 series were considered the most powerful binoculars in the world. These powerful binoculars had some impressive specifications:

  • Oberwerk BT-100-45Weight: 68 lbs (total) 28 lbs (binoculars only)
  • Dimensions : 30 × 15 × 15 in
  • Focal Length: 600mm
  • FOV: 2.5° (25x)
  • Exit Pupil: 4.0mm (25x)
  • Eye Relief: 16mm (25x)
  • Minimum Focus: 15 meters
  • IPD Range: 58-79mm
  • Zoom: 25X

In recent years the production of these powerful binoculars has been discontinued, and Oberwerk now has a new flagship model, the BT-100XL-SD.

As the successor to the BT-100-45 binoculars the BT-100XL-SD binoculars were announced in 2018 and had even more impressive specifications:

  • Oberwerk BT-100XL-SDWeight: 30 lbs (total) 12.5 lbs (binoculars only)
  • Dimensions: 29 × 15 × 12 in
  • Focal Length: 560mm
  • FOV : 1.75° (40x)
  • Exit Pupil: 2.5mm (40x)
  • Eye Relief: 18mm (40x)
  • Minimum Focus: 25 meters
  • IPD Range: 50-80mm
  • Zoom: 80X


Sunagor is the manufacturer of what I think is the most powerful pair of binoculars available in the world.

Sunagor is a company based in London, United Kingdom, and they specialize in manufacturing high end and high strength binoculars.

They have a wide range of binoculars, but their most powerful one is the Sunagor 30-160×70, with an incredible 160X magnification. Another interesting fact about this product is the price tag of just $399,99 and the portability.

Interesting fact: These binoculars have been awarded the 2013 World Record for most powerful magnification.

The Sunagor 30-160×70 binoculars have some very impressive specifications and are what I think the most powerful binoculars in the world:

  • Sunagor 30-160x70Weight: 3.09 lbs (total)
  • Dimensions: 9.7 X 8.2 X 3.15 in
  • Exit Pupil: 2.3mm (30X) – 0.4mm (160X)
  • Eye Relief: 13mm
  • Minimum Focus: 12 meters
  • Zoom: 160X

Rounding up

Here are what I believe are the three most potent binoculars available to consumers. The first two are bulky telescopic binoculars, whereas the Sunagor binoculars are portable and a lot less bulky.
