The provided information does not specify whether the lens of the Bushnell Marine 137500 binoculars can be removed for cleaning. However, since it is described as fully waterproof and fog-proof, it is likely that the lenses are sealed and not designed for user removal.

  • Page 2 1° increments. Ideal for shipboard navigation work or locating objects accurately. A range-finding scale allows the viewer to estimate the range of objects to a known size. The BUSHNELL MARINE is fully waterproof/fogproof and shock protected with suregrip rubber armoring, and has roll-down eyecups for use with sunglasses and prescription eyeglasses.
  • Page 3 HOW TO USE First, adjust the width (interpupillary distance) of your binoculars with the central hinge, so that when you look through them, you see a single circular image. Then focus the binocular for one eye at a time by turning the oculars (eyepieces) until you see an equally sharp image with each eye.
  • Page 4 Each mark on the vertical scale has a value of 5 MIL (1 Mil is equivalent to an angle that can determine an object one meter in height at a distance of 1000 meters). Therefore, if a navigation chart gives the height of an object, by sighting on it and counting the number of MILs, you can determine how far away it is.
  • Page 5 USING THE COMPASS ILLUMINATOR The BUSHNELL MARINE compass model comes with built-in LED compass illuminator for use at night and in low light conditions. (Incidentally, the compass is built into the left tube of the binocular but the push button control for the light and the battery are located in the right tube.
