The 7× power is a little lower than that used on most binoculars intended for land use, there is a reason for this. Firstly, because any movement you make is amplified by the magnification, it makes it much easier to keep the image you are viewing more steady. Something you will really appreciate on rough or even choppy waters.

Secondly, this lower magnification on these also contributes to the wider field of view that you are presented with when looking through these Fujinon binoculars, which is ideal for scanning large open spaces like you will often find out at sea or on a lake.

The very large 7mm exit pupil created by the combination of the 7× magnification and large 50mm objective lenses means that your eyes are certain to be provided with enough light in order for you to perceive a relatively bright image, even in very low light situations when your pupils are dilated.

These use an individual eyepiece focusing system which means that once you have calibrated the binocular to match your vision, no further focusing is required, which makes for a more convenient and quicker to use binocular onboard.

At a full 18mm, the amount of eye relief on these binoculars is excellent and this makes them a great choice for anyone who wears glasses.

Description of Fujinon WP Binoculars

Fujinon offers entry-level Mariner WP series of binoculars that are primarily suitable for boating and sailing, but are also perfect for other nature observations. These binoculars made in China are incredibly well protected and durable so they won’t yield even in the most extreme temperatures, from deserts to subarctic areas. These Porro binoculars are surprisingly lightweight and functional with the help of great optics implemented in them. You can choose between two 7×50 models, where one of them has integrated magnetic and illuminated Suunto compass that helps you with navigation, especially when sailing on the open sea.

Basic Features

Mariner series by Fujinon offers binoculars that are incredibly durable. Hard build materials and rugged rubber armouring protect them against impacts and abrasions in a long run. The construction of these binoculars is also tightly sealed which makes them impervious to moisture, dust and other particles from the outside. They are not only watertight and able to be submersed into water, but are also fog-free so they will never show any signs of internal condensation when quickly switched between different temperatures. Able to withstand severe temperatures in the nature, these WP binoculars will never let you down. The chassis of these binoculars is made out of polycarbonate materials which makes them incredibly lightweight. This means they are definitely one of the less fatiguing Porro prism binoculars on the market and will help you with comfortable portability in the nature.

Optical Properties

WP series is perfect for observations in the challenging light-conditions. Porro prism system makes them incredibly bright with the help of fully multi-coated glass surfaces that enhances light transmission rate. This also provides extremely razor-sharp and crystal clear images with great resolution and color fidelity. When it comes to focusing, these binoculars are able to make proper adjustments even with the differences in person’s eyesight with two focusing rings on eyepieces. This setting also protects them against ingress of water, since central focusing is less watertight. One of the WP model integrates special Suunto Compas that is readable even at night since it’s equipped with illuminated LED display. This setting will help you with navigation even during the nighttime. Compass and its electrical supply are integrated on opposite objectives to eliminate electrical interface. Eyecups also offer great eye-relief and are foldable for those wearing eye glasses.  

Accessories

Fujinon WP series includes eyepiece and objective lens covers for more protection and protective case for storage and carrying. The WP series also includes floatable neckstrap for carrying around the neck and to make these Mariner binoculars floatable if they by any chance fall in the water.
