Built for life on the water

The Mariner WPC-XL is totally waterproof, and floats when used with the included bright yellow flotation strap. It features a wide, large frame that's easy to grip. And its objective lens caps are tethered to its body, so you don't have to worry about losing them while out on the water.

    Hands-on research

    Product Research


    Overview: The Fujifilm Mariner-series binoculars are durable and lightweight. They are designed for marine use, as well as for hunting, camping, bird watching, and other leisure activities. This WPC model features a built-in compass so you can check your bearings. Mariner-series binoculars are ideal for beginners to advanced amateurs, and come with a floatation neck strap, an eyepiece cover, tethered objective lens covers, and a cleaning cloth.

    Construction: The binoculars have a polycarbonate housing to make them lightweight (around 2 pounds). Waterproof O-ring seals help keep water and dust away from the internal optics.

    Multi-coated Optics: Mariner-series binoculars feature fully multi-coated optics to ensure maximum light transmission.

    Individual Eyepiece Focus: The Mariner-series binoculars lack a center focus control, but have individual focus controls for each eyepiece. Users with normal eyesight will find distant objects are clearly in focus when the diopter scales of each eyepiece are set to 0. Near or farsighted users should adjust each eyepiece until each eye sees a sharp, perfectly focused distant image.

    Built-in Compass: The 7x50WPC-XL has a built-in compass that allows you to view your bearings at the bottom of the display as you look through the binoculars. The compass display is illuminated by natural light coming through a small lens on top of the left tube of the binocular. The built-in LED can be turned on for viewing the compass in low light or at night. Two LR43/186 batteries are included to power the LED.

    Rubber Eyecups: The non-adjustable rubber eyecups offer long eye relief (18mm), allowing you to get a full field-of-view through the binoculars, even while wearing eyeglasses. The binoculars have an interpupillary distance adjustment so that you are viewing a single image when looking through the eyepieces.

    5 Year Warranty: The Fujifilm Mariner-series binoculars are protected by a 5-year Limited Warranty. The warranty term begins when the product is registered within 10 days from the date of purchase (or in case of a gift, from the date of receipt). The warranty applies to the original end user, and does not cover rubber or accessories.
