Swift Sport Optics Swift 7x50 Sea King, Water Proof Porro Prism Binocular with a Lighted Internal Compass, with 7.0° Angle of View.

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.

Since 1926, Swift binoculars have been the reliable, and sometime life-saving companion of professional amateur mariners-and the right arm of sportsmen.

All of these glasses incorporate the finest quality lenses and prisms, plus hard amber and/or magenta coating to reduce reflection and internal glare. These superb optics are housed in precision cast, finely machined and anodized bodies of ultra-light alloy.
