Swarovski (swarovskioptik.com) no longer offers gyro-stabilized models, but the company recommends several of its waterproof 8x magnification glasses for marine use. (Binoculars stronger than 8x could be too unsteady in bumpy seas and have been known to make users seasick.) Swarovski's EL 8x32 glasses are lightweight, have a 423-foot field of view at 1,000 yards, and retail for $2,443. The EL Range 8x42s can measure the distance to objects up to 1,500 yards away, have a 411-foot field of view, and are priced at $3,632. The SLC 8x56 binos, which are optimized for night use and have a 400-foot field of view, sell for $2,399.
