Question about West Marine Moorea Waterproof Binoculars
I have misplaced the instructions for my binoculars and would like to know how to use the rangefinder.They are the Moorea 7x50 with the internal compass and rangefinder. Or maybe can I download an instruction booklet from somewhere?
How to use the reticle:
The vertical scale (reticle) visible through the left half of the binocular, above the compass display, allows you to calculate distance to an object if you know its height, or to calculate the height of an object if you know its distance from you.
Each mark on the vertical scale has a value of 5 MIL (1Mil is equivalent to an angel that can determined 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.
To Measuer distance when height is known:
Object Height(m)/Scale Reading x 1000m=Distance in Meters
To Measure height when distance is known:
Distance(m)xScale Reading/1000=Object height in meters

Without seeing a picture it is difficult but there is hope. Most binoculars branded by companies other than the big three come from China. Namely the Kunming United Optics Corporation. Just type in United optics China into google. Have a look at the BC 6 in the compact binoculars section they may look like your ones. Not many 8x26 units are nitrogen filled so I'm guessing on this one. They have a support section and may be able to help.

They were isued to the German army. My father bought a pair from a destitute soldier sitting on the wharf in Hamburg in 1945. I want to sell them now, but dont know what they are worth.
