Swift SeaKing 7x50 Binoculars With Compass

Swift 7x50 Sea King, with a lighted internal compass, BAK-4 fully coated Porro prisms and nitrogen-purged water proof case. The Sea King is represents a "serious" offshore binocular, and the difference is immediately apparent when looking through the ocular lenses. The image is crisp, focus was a breeze and the compass' vertical and horizontal reticle scales provided the kind of information that is vital to good piloting.
