7 × 50 WPC-XL (with Compass)

Designed for use on the water, with an airtight, waterproof structure filled with nitrogen gas. Thanks to their polycarbonate body, these binoculars are lightweight and dependable.
The large 50mm objective lenses let in a copious amount of light, making it easy to see your target object.
Designed with comfortable 18mm long eye relief for easy viewing with minimal eye strain. The long eye relief also allows a user with glasses to have full visibility of the field of view.
The 7x50WPC-XL has a high-precision built-in compass with maximum error of ±0.5°. The scale can be used to identify the object’s direction, measure distance, and determine the size of the object.
The compass is global, accurately measuring direction in both northern and southern hemispheres.
The compass has an internal light to view scale during the night.

Using the Compass

There are two main ways of using the compass built into the 7x50 compass type binoculars.

Identifying direction of travel

You can work out your current direction of travel relative to a buoy by calculating the difference between the number displayed when looking at the buoy and the number displayed when looking in the direction of the bow. In the example on the right, the compass reads 270° when looking at the buoy and 240° when facing the bow, indicating that the boat is traveling 30° to the left of the buoy.

Measuring size and distance

If you know either the size or distance of a target, you can roughly calculate the other. The lighthouse in this example is 10m in height and the scale is showing 40 mils. The approximate distance can be calculated with a simple equation.
