Product Differences

Why are Commanders more expensive than Navigators?

The Commander Series binoculars are built to a military specification. If you live on the water or make your living on the water, the Commanders are built to last. They also have better seals for greater protection again moisture, enhanced lens coatings that transmit more light and Steiner Nano Protection, a coating on the external lens surface that makes water, dust and oil slide off the lens for a clear view.

What is the difference between Safari/Safari Pro and Safari UltraSharp?

While Safari and Safari Pro are similar in design and appearance, the Safari UltraSharp represents a newer generation with enhanced features and better lens coating. The Safari Sports-Auto-Focus-Plus™ hybrid system lets you see objects as close as six feet, so it's a great entry level binocular for birding and wildlife observation.

What ist the difference between roof and porro prism design?

Porro and roof prisms are two different types of optical systems and each has its advantages. With Porro prism binoculars, the eyepiece and objective lenses are offset. This means the light must follow a Z shaped path to reach your eye. Although slightly larger than roof prism binocular, porro prism binos are extremely rugged and easier to make waterproof. Because the objective lenses are offset, they offer a 3-D view with better separation of targets at a distance. In addition, with Steiner's Sport-Auto-Focus, you only have to focus the binos to your eyes for everything from 20 meters to infinity to be in focus. True one-handed operation.

Roof prism designs transmit the light or image to your eye in a straight path. For this reason, they are more compact. They also feature a center focus knob that can be easily adjusted for sharp focus beginning from to 2m to infitity. They are pretty rugged and durable, but harder to make waterproof to any significant depth.

Which batteries goes into each binocular compass model, scope or laser range finder?

The only optics that need batteries are those equipped with illuminated compass, illuminated reticle, or a laser rangefinder. Here is list of those optics and the batteries required:

  • Nighthunter LRF 8x30 – CR2
  • LRF 1700 8x30 - CR2
  • LRF 1700 10x30 - CR2
  • Navigator/Commander 7x30 C – CR 1225
  • Navigator 7x50 – CR 1225
  • Commander 7x50 C – CR1/3N
  • Commander Global 7x50 – CR 2
  • Nighthunter Xtreme Zielfernrohr – CR 2032
  • Ranger-Scope – CR2032
  • MRS – CR1632

Which compass zone is right for me?

In order to get an accurate compass-heading reading from a compass, the magnetic needle in the compass must be able to move freely inside the compass capsule. The needle must be balanced to make sure it can move freely, without touching and dragging along the top or bottom of the capsule; while consistently and precisely point to a compass-heading.

  • The compass industry has divided the earth into 5 zones. Your compass is preset for the magnetic field in the northern hemisphere (Zone 2) if bought in this area. If you sail too far outside of the preset zone, the compass needle might stick or not work at all. Many transoceanic sailors will take 2 or 3 binoculars with different zones.
  • Changing compass modules is not a Do-It-Yourself project. You can send your binoculars to our Service Center if you need a different compass zone.

If you are a frequent world traveler, we recommend the Commander Global: No calibrating or adjusting: the Global Compass is the absolute pinnacle and once again demonstrates STEINER's skill in creative innovation. The integrated electronic magnetic field measurement ensures absolutely precise readings, everywhere in the world from the Arctic Circle to the South Seas. Thanks to its digital technology, the bearing is extremely precise. Analogically superimposed on the lower edge of the image, the display is especially easy to read without disturbing the field of vision. The intuitive operation and the compensation for inclination angles make handling especially easy and reliable. You will be thrilled with the decisive functional advantage of the Commander Global.


Both sides are clear but when I look through both it’s fuzzy or feels cross eyed?

Your binocular has been knocked out of alignment or collimation. Because the two lenses are no longer aligned they are sending slight different images to your eyes, which as make it look fuzzy. If that should happen, it is a simple repair.
