One of the most important pieces of equipment on a boat is binoculars, which are especially important when visibility is poor and you need to navigate at sea or in an archipelago. With binoculars, you can see landmarks clearly and quickly at sea, making it easy to determine your location on a map. High-quality marine binoculars are nitrogen-filled and waterproof.
The highest magnification generally found to be usable for a moving and rocking boat is 7x. Magnifications higher than this require image stabilization in boating conditions. Thanks to image stabilization, the image is very stable even in rough seas, even with binoculars with 15x or 18x magnification.
Some models have a built-in compass and rangefinder scale.
