Military 20x80

Military ruggedness and precision

For tactical observers these high power binoculars are easy to use, give a better view and offer a lot more comfort during extended use than spotting scopes. And the 80-mm objective lenses, combined with STEINER's legendary optics, deliver far superior low-light performance. These STEINER Military 20x80 binoculars were originally developed for perimeter and border patrol applications and are mil. spec. tough: totally waterproof, shock resistant, and rubber armoured. Tripod mount is also included, but this binocular is light enough to be hand held.

Also available with Reticle (R) and/or Laser Protection Filter (LPF).

Our outstanding product features:

MANAGEABILITY

STEINER's special compact construction shifts the center of gravity into the palms of the user's hands and allows a long-time observation without getting tired.
The round shoulder shape of our binoculars is absolutely necessary to enter and leave armoured vehicles such as tanks without hindrance.



LONG LASTING RUBBER AMOURING

STEINER's long-lasting, slip-proof and noiseless protective rubber armouring with its webs gives a perfect firm grip, in cold, heat, rain, sea water and the sun's rays as well as additional protection against environmental influences. The long lasting rubber amouring is extremely rugged and resistant against oil, acid, and salt water. This rubber armouring is slip-proof, noiseless and shock-absorbing thus makes the binoculars comfortable to hold at a maximum ease-of-use.



EXTREME RUGGEDNESS and LIGHTWEIGHT

Binoculars from STEINER withstand the toughest demands made on them. They feature an extremely compact and resistant design that can cope with the most demanding conditions. STEINER's special optical military construction guarantees stability even under severe shock and vibration conditions - due to their unbreakable Makrolon inner housing our binoculars are extremely rugged and lightweight.



NITROGEN PRESSURE FILLING via 2-WAY-VALVE SYSTEM

STEINER's genuine military binoculars are the only ones which have a two-way valve system which means that prior to the process of filling the binocular with nitrogen the normal and humid air existing in the interior of the binocular will be sucked off and when there is a vacuum inside the dry nitrogen will be blown in. Fogging up or the formation of condensation inside the binoculars is totally prevented by this high-tech solution. Only this method fully guarantees an absolutely condensation-free use of the binocular during changing temperatures and in altitude differences. Even temperature variations between -40° and +80°C do not have any adverse effects on the functionality of STEINER nitrogen-filled binoculars. The unique 2-way-valve technology makes inspection, service and maintenance possible even after a number of years. The binoculars are always ready for action under the most extreme conditions or in the worst weather conditions. Optical quality and precision are maintained for decades.



WATER PRESSURE PROOFNESS

STEINER's genuine military binoculars guarantee a tightness/pressure-proofness of 0.5 bar which corresponds to a water pressure proofness of up to 5 m depth of water. Special sealing technology protect the high-end optics from outer influences. No dust, no dirt and no humidity can penetrate into Steiner binoculars.



TEMPERATURE RANGE

As per general military requirements STEINER's binoculars withstand temperature ranges from -40° to +80° C.



PORRO-PRISM SYSTEM

Porro-prism systems are used in almost all of the high-quality binoculars. These binoculars are extremely rugged. This system creates a perfect three-dimensional image and its construction increases light transmission. STEINER's military binoculars offer a bigger depth of field since the two objective lenses are further apart from each other. This has the big advantage that the observer can clearly judge at distance whether one object is behind or in front of another.



INDIVIDUAL EYEPIECE FOCUS

The STEINER individual eyepiece focus makes observing particularly comfortable. If both eyes are of the same dioptre strength, simply set both of the adjusting rings on the eyecups to "0" and you will see clearly from 20 m to infinity. If not, adjust both oculars individually for razor sharp images. Once adjusted, everything will be sharp and clear from approx 20 m to infinity for varying distances. Simple use. Also with a single hand only.



MULTI COATED OPTICS

STEINER's multi coated optics provides outstanding viewing quality due to extremely high light transmission. All lenses and prisms are manufactured with maximum precision and are specially coated and deliver optimum observing results. Such state-of the art optical technology guarantees absolutely bright, high-contrast and sharply contoured images with natural color definition.



RETICLE

Distance or size of objects can be easily determined with the help of a reticle.

Other reticle patterns as per customers' requirements can be developped.

Calculating Distance:
With a known height or width of an object, it is easy to determine how far it is away.
Formula: size of object x 1.000 / scale value (mil) = distance
When this formula is used, the distance will be given in the same units of measurement (feet, meters, etc.) as is used in estimating the known size of the object. The same formula can be used to determine range with the vertical retical scale when height of an object is known. The use of the vertical scale is preferred (especially on level terrain), since objects are often viewed obliquely along the horizontal axis.

Calculating Size:
With a known distance, the size of an object can easily be determined by using the reticle.
Formula: distance x scale value (mil) / 1.000 = size of object



LASER PROTECTION FILTER

Since laser protection has become an important issue with regard to optical observation devices years, all STEINER military binoculars can be supplied with a laser protection filter, either our standard one (OD 4 / 1064 nm) or a filter as specified by the users and customers.
STEINER was the first company in the world who developped, offered and manufactured a binocular with laser protection filters. Since the time when we started our development and research work in this field, we have gained a tremendous additional amount of experience and knowledge in this technology.
