The Quest HD L allows you to explore the underwater world in razor-sharp, high-definition detail. A full 1080p camera paired with MarCum’s exclusive relative direction, depth, and temperature readings join to create a superior viewing system.  Scan the depths with power to spare, thanks to the MarCum Brute 12V10AH Lithium LiFePO4 battery and charger. Combine these features with the brightest screen MarCum has ever produced plus 75 feet of camera cable, and the Quest HD L delivers the most optically advanced underwater viewing experience ever devised.
