These are the binoculars I use.
They are waterproof and fog proof and have a built-in illuminated compass. The rubber armored exterior
makes them easy to hold in wet conditions. The compass appears at the bottom of the left eye piece and
allows you to take bearings on aids to navigation. You may also use the bearing of another vessel to
determine if there is a risk of collision.<!--more-->

marine use, more that 7 power magnification becomes very difficult to hold steady.
