Ideal for extended OFFSHORE fishing or wilderness excursions, the Marine Elite? Offshore Series takes cooler performance to a whole new level! Outstanding features include extended ice keeping ability made possible by Cool Riser Technology?, gasketed lids and extra-thick insulation inside virtually indestructible polyethylene shells. 50-, 70- and 150-quart models include a convenient raised cutting board surface in their lids. All models include a molded-in fish measuring ruler. Finger-friendly rubber latches make these coolers easy to open when your hands are cold, and rugged, wide-grip, integrated handles accommodate large and gloved hands. The 70-quart model fits nicely under most leaning posts, and with extra-thick insulation, less ice is needed, which gives you more space for fish!
