A device for use in making beach entry scuba dives by assisting the diver to transport scuba tanks and other diving gear across a beach or like land area and then serve as an off-shore floating work platform and dive flag holder has a quadrilateral frame, a roller unit and a handler unit. The frame is formed of hollow tubing and includes a force member, an aft member, and a pair of side members. The roller unit includes first and second arms that extend from the frame beyond the aft member, a buoyant roller, and bearings rotatably supporting the roller between the arms outboard of and parallel to the aft member. The handler unit includes third and fourth arms that extend from the frame beyond the fore member and a tubular handle member supported by the third and fourth arms outboard of the fore member. The frame carries a support surface and straps to support and retain tanks and other gear on the device.
