Navigating underwater isn’t as easy as it looks. Currents, visibility and even seascape can make navigating difficult. Learn how to be more in control of your dives by being able to navigate to the boat, shore or meeting point underwater. In this course you’ll learn navigation patterns, natural navigation (without a compass) and compass navigation. You’ll also learn how to “mark” or relocate a submerged object or position from the surface, underwater map making, how to follow irregular courses with the Nav-Finder Dive site relocation and how to estimate distance underwater.
