Quick Overview

THE ONLY THING WE DIDN'T DO IS TEACH THEM TO SWIM.

The ultimate on-the-water viewing companions, our everpopular H20™ binoculars have been enhanced for 2012 with a Soft Texture Grip to keep them on board and in your hands in the most challenging conditions.

Just as before, they're O-ring sealed and nitrogen purged to ensure stunning views no matter how wet they get. To maximize light transmission and clarity, standard equipment includes multi-coated optics and premium quality BaK-4 prism glass. From the streamside to the Gulf Stream, the world simply looks better through the Bushnell® H20.

Compact and ready for any wet-weather application.
 
  • BaK-4 prisms for bright, clear, crisp viewing
  • Multi-coated optics for superior light transmission
  • 100% waterproof: O-ring sealed and nitrogen purged for reliable, fog-free performance
  • Non-slip rubber armor absorbs shock while providing a firm grip
  • Twist-up eyecups
  • Large center-focus knob for easy adjustments
  • Longer eye relief
  •  

    Multi-Coated Optics

    Multi-Coated optics for superior light transmission and brightness. 

Eye Relief

The distance a binocular can be held away from the eye and still present the full field-of-view. Extended or long eye relief reduces eyestrain and is ideal for eyeglass wearers

Prism System - Roof

In roof prism binoculars, the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, streamlined shape in which the lenses and prisms are in a straight line. Roof prism binoculars are less bulky and more rugged than an equivalent porror model.

Prism System - Porro

In porro prism binoculars, the objective or front lens is offset from the eyepiece. Porro prism binoculars provide a greater depth perception and generally offer a wider field-of-view. Because of the simplicity of this system, some of the best values can be with a porro design.

Waterproof/Fogproof

Some binoculars are O-ring sealed and nitrogen-purged for total waterproof and fogproof protection. These modesl can withstand complete immersion in water and stay dry inside. The interior optical surfaces won't fog due to rapid temperature change or humidity.

Magnification (Power)

Binoculars are often referred to by two numbers separated by an "x". For example, 8x32. The first number is the power of magnification of the binocular. With an 8x32 binocular, the object being viewed appears to be eight times closer than you would see it with the unaided eye.

Objective Lens

The second number in the formula (8x32) is the diameter of the objective front lens. The larger the objective lens, the more light that enters the binocular and the brighter the image.

Prism Glass

Most optical prisms are made from boroscillicate (BK-7) glass or barium crown (BaK-4) glass. BaK-4 is the higher quality glass yielding brighter images and high edge-to-edge sharpness.

Coated Optics

Lens surface coatings reduce light loss and glare due to reflection for a brighter, higher-contrast image with less eyestrain.

Types of Lens Coatings

  • Coated: A single layer on at least one lens surface.
  • Fully Coated: A single layer on all air-to-glass surfaces.
  • Multi-Coated: Multiple layers on at least one lens surface.
  • Fully Multi-Coated: All air-to-glass surfaces feature multiple layers of anti-reflective coating. Fully multi-coated optical systems deliver the brightest, highest-contrast images with the least amount of eye strain because only a very small percentage of light is lost before it reaches the viewer’s eye.

 

Field-of-View (F.O.V.)

The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide-angle binocular features a wide field-of-view and is better for following action. Generally, the higher the magnification, the narrower the field-of-view.

Resolution

Resolution, or definition, is the ability of a binocular to distinguish fine detail and retain clarity.

Exit Pupil

Refers to the size of the circle of light visible at the eyepiece of a binocular. The larger the exit pupil, the brighter the image. To determine the size, divide the objective lens diameter by the power (an 8x32 model has an exit pupil of 4mm).

Diopter Adjustment

A "fine focus" adjustment ring usually provided around one eyepiece to accommodate for vision differences between the right and left eyes.
