Product Description


  • Waterproof and Fogproof
  • Roof Prism
  • 6.7° Angle of View
  • Center Focus


The Pentax 7x50 Marine Binocular is that rarest of breeds, a center focusing 7x50 unit with an internal compass and reticle.  Most of the 7x50 boating binoculars are porro prism models with individual focusing.  Many users prefer the roof prism configuration because of the identical barrel spacing to one's eye, and nearly all would choose center focusing over individual focusing if they had the choice.


The 7x50 Marine has an internal compass that uses LED illumination, the most battery-efficient of all, to display its readings.  There's also a rangefinding reticle scale, which aids your estimations of the distances of other boats (when their approximate height is already known).  The 7x50 Marine is meant for use on water, built to withstand the elements and protected by Pentax's fine "Worry Free" warranty in any case.

Ideal magnification and objective size for use upon water, combined with comfortable roof prism/center focus design
Waterproof/fogproof nitrogen filled body meets JIS Class 6 weatherproofing standard (resists ingress from powerful water jets propelled at any angle)
