Global precision
Commander Global 7×50 Compass
The yearning for faraway places and unbounded freedom on the high
seas – experiences as old as seafaring. Thundering winds, white-crested
waves and the untamed forces of nature are the eternal challenges for true
adventurers.
Ever since Christopher Columbus, Vasco da Gama and Ferdinand Magellan
first tasted salt on their lips, this unique fascination has not changed over
the centuries. Advanced boat construction and the latest materials in
shipbuilding have now reached a level of technical perfection that these
heroic explorers could not even imagine. In this spirit, STEINER set the goal
of once again reinventing the compass binocular so that it could be used
anywhere in the world and thereby created the ultimate flagship model of all
marine binoculars.
In the new Commander Global the entire experience and creative
innovation of the traditional family business is manifested
in an outstanding high-performance lens. STEINER has
combined the brightest cutting-edge optics with a
precise global compass in a peerless instrument
for the first time. As a yacht owner in the port of
Monte Carlo or rounding Cape Horn, with the
Commander Global you will demonstrate not only
your passion for perfection but will also be able
to meet the greatest challenges facing your team
and materials with style. The ideal equipment for
anybody who won’t be satisfied with anything
but the best.

STEINER Diamond-Marine-Coating
The world’s best binoculars for use on the high seas around the world – this
is the goal STEINER, the inventor of compass binoculars, set when deciding
to develop its latest flagship instrument. The result: the Commander Global,
the one-of-a-kind combination of a highly precise compass with the brightest
high-end optics to ever be used in a marine binocular. The compass lens is
extremely rugged and practically indestructible thanks to the Makrolon®
housing, nano coating and the NBR-Longlife Rubber Armouring. With its
precision lenses and an innovative high-tech Diamond-Marine-Coating, the
Coating developed especially for marine
use – for flawless bright images in all light
conditions right into the night
Commander Global offers superb optical performance with previously unattainable light transmission combined with the proven Sports-Auto-Focus.
The STEINER ComfortGrip with gel pads, the new strap system and the
well-designed accessories ensure long-lasting secure and comfortable use.

STEINER Nitrogen-Pressure-System ONLY THE BEST IS GOOD ENOUGH
With the Commander Global, STEINER is now employing its latest achievements in the development of especially bright optics for the first time.
Adapted for use in the seafaring environment, the new Diamond-MarineCoating gives you optics with previously unattainable light transmission over
the entire visible spectrum. Rare fluorides and mineral substances are used
in this high-tech coating, offering a razor-sharp image with the highest level
of contrast right to the edge of the field of view. Contours are always clearly
and distinctly visible, and diffused light is reduced to a minimum. The
decisive difference becomes especially apparent in fading light and after
the onset of darkness. The Commander Global offers optimum safety in
situations in which exact observation and correct bearings under difficult
conditions are critical.

The size of the compass is critical for the stability
and precision of the bearings. With a diameter
of 40 mm, the integrated high-end compass
of the CommanderXP 7×50 is a market leader.
The improved fluid damping and the
user-friendly illumination function will give
you that little bit of extra security on the
high seas. The reticle makes it possible to
calculate size and distance with absolute
precision. The CommanderXP 7×50 is your
functional companion under extreme conditions
that you can rely on in any situation.
CommanderXP
7×50
You give your very best for boat and crew in extreme situations. You master
the challenges of sudden gales and heavy seas. Yet the responsibility remains
always with you. Your experience tells you: The precision and reliability of your
instruments are vital. That’s why you don’t compromise when choosing your
equipment. As innovative as possible and as simple and rugged as necessary:
over 30 years of developing compass binoculars are behind the
CommanderXP 7×50. A set of binoculars meeting the highest standards for
ruggedness, precision and innovation was created after extensive discussion
with world sailing champions. No matter which waters you sail, which port
you steer to in your boat, the CommanderXP 7×50 offers you the
benefits and the ruggedness that you desire. Absolutely reliable
and highly precise. The entire construction with its Makrolon®
housing, NBR-Longlife Rubber Armouring and floating prism
mounting as well as Nano-Protection® is designed to resist
environmental factors and tides and to be indestructible
when it comes to shocks and water. At the same time the
High-Definition-Optics along with the Sports-Auto-Focus
offer an especially sharp, clear and bright image that makes
observation possible even under difficult conditions and at
night. In addition to its practical handling and the sensible
accessories, the CommanderXP 7×50 also stands out as truly useful
and functional.

Compactness and performance need not be mutually exclusive. STEINER
has compressed the superior binocular technology of its big brother, the
CommanderXP 7×50, into a compact 7×30 format.
The result: A handy binocular that offers a much higher level of performance
than you would expect from the compact class, making the CommanderXP 7×30
thus the perfect companion for people who put stringent demands on their
marine binoculars but at the same time attach importance to compact
dimensions and light weight. It’s simply ideal for comfortable use on land as
well. And you don’t need to forgo the image quality of the High-DefinitionOptics or the typical ruggedness and resilience of the top models either. The
sum of its many advantages means the CommanderXP 7×30 clearly surpasses
even some 7×50 binoculars on the market.

The shock absorbing fluid determines the direction is effected with highest precision. Operation of the compass illumination is easy, without
changing hands, and the tactile handling
allows a bearing to be taken at sea, even
under difficult weather conditions. The NBR

additional protection and always ensures
the Navigator Pro remains a reliable
companion.
Pressure proof up to 5 m
The revised NBR Rubber Armouring with STEINER ribbing makes the
binoculars even more tactile; they also stay firmly in your hand in the wet
and in rough seas. The N2-Pressure-Filling in the binoculars, via the patented STEINER 2-way-valve technology, prevents the formation of condensation and fogging on the inside of the binoculars. The Navigator Pro series
stays waterproof up to 5 metres.
The newly developed neoprene carrying strap can
be attached to the binoculars by modern
ClicLoc Strap Attachment and thus
enables perfect balance. The carrying
strap is not only easy to detach, but

STEINER High-Definition-Optics
Eyecups Cylindric-Soft
Temperature resistant
Optimally suited for regular, professional use. A highly specialised coating
provides first-class light transmission. The images are pin sharp and of
the highest contrast – right to the edge. Diffused light is reduced to a
minimum. Contours are always sharp and distinctly visible, even in poor
light or at the onset of dusk.
Like all eyecups by STEINER these too are made of soft, pliable and
skin-friendly silicone. They can be adjusted two ways:
1. Cylindrical – as the classic setting variant.
2. Folded over – for use with eyeglasses.
Even temperature variations between -40 °C to +80 °C or
-20 °C to +60 °C will not adversely affect the functionality
of a STEINER binocular.
STEINER High-Contrast-Optics
STEINER Memory-Ocular
NBR-Longlife Rubber Armouring
STEINER’s High-Contrast-Optics give outstanding viewing whether
for beginners or passionate hobby-skippers! All lenses and prisms are
manufactured with precision and are specially coated. You get highcontrast, bright views with natural colour definition.
Via the handy ratchet mechanism of the memory ocular you can store
your personal dioptre setting. By turning the ocular, you will immediately
find your personal setting again.
The especially durable NBR-Longlife Rubber Armouring is
resistant to the effects of oil, acid or weathering. The surface
always stays easy to grasp and slip-proof even in extremely
wet conditions, heat or cold.
STEINER Diamond-Marine-Coating
STEINER Nitrogen-Pressure-System
Fogging up or the formation of condensation inside the binoculars is
totally prevented by this high-tech solution from STEINER. Even
temperature variations between -40 °C and +80 °C do not have any
adverse effects on the functionality of STEINER binoculars filled with
nitrogen. The 2-way-valve technology makes maintenance possible at
any time even after many years of use.
STEINER’s unique Diamond-Marine-Coating permits a previously
unattainable light transmission over the entire colour spectrum. Even
at night or at dusk, you will see perfect, bright images that have not been
possible before.
STEINER Nano-Protection®
The proven STEINER Nano-Protection® permits unsurpassed clear viewing.
It gives the lenses a dirt and water repellent surface and thus protects them
from aggressive environmental influences. Rain, snow and moisture
disappear from your field of vision. Cleaning is made considerably easier
and stubborn dirt is a thing of the past. The wafer-thin, hydrophobic surface
coating on ocular and objective lenses is extremely robust and will give you
a high-contrast and brilliant image for many years.
Water pressure proof
5/10 m
Marine lenses from STEINER resist water pressure down to a depth of
5 m (Navigator Pro) and 10 m (Commander Global and CommanderXP)!
Special sealing technologies make it possible. No dust, no dirt and no
humidity can penetrate into the binoculars. This technology protects your
binoculars from external impacts.
Technical Data
STEINER Sports-Auto-Focus
Once adjusted, the unique STEINER Sports-Auto-Focus
always provides razor-sharp images from 20 m to infinity.
Without refocusing.
Extreme Ruggedness
The Makrolon® material used in the construction makes the
housing even more shockproof and thus much more
rugged. The prisms have “floating” mountings. That means
that they are fixed with a durable, flexible silicone material to
protect the valuable optical components inside.
24-hour binocular
High transmittance thanks to the 50-mm objective lens and large exit
pupil. With 7 power magnification; even in heavy swells, wiggle-free view
round the clock.
STEINER ErgoFlex eyecups
This innovative system offers the user superb viewing comfort and
reliable protection against incidental light from the side as well as wind/
draughts. The ErgoFlex eyecups are made of non-irritating and
non-ageing silicone, which provides a naturally comfortable feeling on
the eyes and can also be adjusted three ways by simply folding it over:
1. Ergonomic – for ideal conformity to the shape of the face.
2. Cylindrical – as the classic setting variant.
3. Folded over – for use with eyeglasses.
STEINER ComfortGrip
The Steiner ComfortGrip System guarantees uniquely comfortable
handling. The Technogel® thumb depressions give a sure, light and
pliable grip, which prevents premature fatigue and permits a considerably longer period for observation. You won’t want to let these binoculars
out of your hands!
STEINER ClicLoc Strap Attachment
With the carefully thought-out STEINER strap attachment, the binoculars
always remain firmly in the strap! The carrying strap, can, however, be
released and refastened in one easy move. The comfortable strap and
floating strap can be switched quickly and easily.
Ergonomic design
Lies perfectly in your hand and the good gripping
characteristics of the contact ribs offer sure handling.
High-quality accessories

protection cap for eyepieces and objective covers and is
delivered with a high-quality case or gear bag.
