Since time immemorial, an aura of mystery has surrounded the tanks holding fuel, water and waste aboard a sailboat. Enter the Gobius tank measuring system, which uses vibrations to determine how full a tank is. Each Gobius includes a control unit and a series of sensors, each equipped with a “shaker” and an accelerator to create a “knock and listen” system to determine if there is liquid on the other side of the tank wall. The Gobius works on fuel/water/waste tanks made of steel, plastic, fiberglass or aluminum, and can be installed in less than an hour.
From $330. For more on the product from Gobius/AB Marine, click here.
