class="amshopby-descr">Ever wanted to sketch or make notes while underwater? AquaSketch is exactly the device that can help you do so. Created by an illustrator, who wanted to draw while diving, and an industrial designer, working for NASA, AquaSketch is the most advanced underwater notation and reference system up to date. The tool uses an interchangeable scroll of waterproof vellum, and can be worn on the wrist for diver’s convenience. Thanks to high durability and versatility of such a system, it is widely used by NASA, the U.S. Military, marine researchers, as well as search and rescue organizations. What’s more, the tool can be also used in other extreme settings.
