The U.S. Coast Guard suggests you keep them on board, but Bushnell made the Marine 7x50 binoculars buoyant, waterproof and corrosion resistant, so a little dunking won't deep-six your day. You'll appreciate the ultra-bright, crisp views granted by their multi-coated optics and premium BAK-4 prism glass. Rugged rubber armoring provides a sure grip, absorbs shock and keeps them from sliding in rough conditions. They're essential equipment if you spend much time on deck, and aren't fazed by a little time off it.

The range finder option, does it calculate the range automatically or do you have to manually adjust it?
The range finder option is actually a reticle that you will see when you look through the binocular. 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 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 MIL's, you can determine how far away it is. Here are two formulas: To measure distance when the height is known: Objective Height (m) / Scale Reading X 1000m = Distance in Meters To measure object height when the distance is known: Distance (m) X Scale Reading / 1000 = Object Height in Meters

What does 7x50 mean?
The first number before the X is the magnification of the binocular. The second number is the objective lens diameter, measured in millimeters. So for example, this binocular will make an object appear to be 7 times closer than the naked eye and have a 50mm objective lens.

What does the 303 ft. at 1000 yards mean?
It means that the field of view will be 303 feet wide at 1,000 yards. In other words, you'll be able to see an area 101 yards wide at 1,000 yards' viewing distance.

What is the peak light transmission (over 90%) of these binoculars?
These binoculars have 94% peak light transmission.
