All lenses, prisms, and dustproof glass are fully multicoated, ensuring a clear visual range and sharp images.
The PROMINAR model (BL8J3) with pure fluorite crystal objective lenses is available for those seeking the highest optical performance.
The strong yet lightweight die-cast aluminum housing is extremely durable, with a rigid structure that can endure tough use. The built in handle on the body provides an easy means of carrying.
The housing is waterproof to JIS* Protection Class 7** and filled with dry nitrogen gas to prevent the lens from fogging.
*JIS=Japanese Industrial Standard.
**Not intended for use underwater.
The eyepieces are designed to provide a wide field of view and long eye relief for comfortable viewing without eye fatigue.
To install the eyepiece, place it in the opening and push until the eyepiece hits against the top of the focus ring. To remove the eyepiece, simply pull the eyepiece straight out of the focus ring.
The interpupillary distance is adjusted by moving the eyepieces left and right. Focusing of the binoculars is achieved by turning the focus rings (located below the eyepieces).
The sightline is useful for finding the object you wish to view.
By aligning the sightline on the handle and the protrusion on the main body, objects can be easily sighted.
When facing the sun, pull out the sunshade to keep unwanted light from entering the binocular.
