The most compact professional marine binocular
With its extremely light weight of 520 g the Navigator 7x30 represents a new dimension of marine binoculars. Comfortable handling and ease of use in combination with the unsurpassed ruggedness makes it the perfect companion aboard and ashore.
Like no other binocular in its class the Navigator 7x30 provides a professional functionality paired with an unequalled price-performance ratio. With water pressure proofness to 2 meters and powerful High-Contrast-Optics for clear images, it guarantees quality and safety.
STEINER’s legendary Sports-Auto-Focus ensures instant sharp viewing in any situation even at varying or rapidly changing distances — no need to constantly refocus. Added comfort with the slip-proof rubber and the shock-absorbing Makrolon® fibre reinforced polycarbonate body. A fog-free viewing and moisture protected performance guarantees the two-valve system of dry nitrogen pressure filling.
Our outstanding product features:

STEINER High-Contrast-Optics
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.
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.
Water pressure proof
All Navigator models resist water pressure down to a depth of 2 m! 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.
Eyecups Cylindric-Soft
Like all eyecups by STEINER these too are made of soft, pliable and skinfriendly
silicone. They can be adjusted two ways:
- Cylindrical — as the classic setting variant.
- Folded over — for use with eyeglasses.
10 year warranty
We offer a 10 year warranty. If you need a repair, our team of technical experts will check out your binoculars and repair them within the terms of the warranty agreement. Simply send your binoculars
to us directly or to your dealer.
The STEINER Marine Standard:

Temperature resistant
Even temperature variations between -40 °C to +80 °C
will not adversely affect the functionality of a STEINER
binocular (for details see table).
NBR-Longlife Rubber Armouring
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 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.
Ergonomic design
Lies perfectly in your hand and the good gripping
characteristics of the contact ribs offer sure handling.
High-quality accessories
Every binocular is equipped with carrying strap, rain
protection cap for eyepieces and objective covers and is
delivered with a high-quality case or gear bag.
