Thus, IS binoculars allow boaters to opt for higher magnification. Yet binoculars that could lock on to what you really need to see have been out of the reach of most recreational boaters.īut thanks to Image Stabilization (IS) technology developed to take the shakes out of hand-held video recorders, affordable binoculars are now coming on the market that either mechanically or electronically dampen movement, seeming to lock on an image. They have very high magnification and make everything hold still. If you've been boating for awhile, there doubtless have been times when you could really use those big gyroscopically stabilized binoculars that the U.S. That's why 7x50s (seven times the magnification with a 50-mm objective lens for optimum light gathering), has become the standard for recreational boaters. It's the swell, it's engine vibration, it's boat speed - most of all, it's you. The human hand just can't hold binoculars steady enough for most maritime applications beyond seven-power magnification but it's not the glasses. Boat Owners Association of The United States
