A collapsible, height adjustable support device with inflatable buoyancy floats for mounting articles particularly cinematographic apparatus upon and below the water. It is characterised by a central tubular frame ( 1 ) with a plurality of detachable support arms ( 2 ) perpendicular to the central frame. The support arms also attach to the elongate inflatable buoys ( 1 0). Cinematographic apparatus is mounted upon a fixing plate ( 5 ) positioned centrally on the central frame member ( 1 ). The adjustable height of the mount above and below the surface of the water, is facilitated by the angular relationship of the central longitudinally splined frame member ( 1 ) and each support arms splined hub. Footpads ( 4 ) with releasable locking pins and receiving plates ( 22 ) provide attachment of support arms to the floats ( 10 ). Anchorage and tether points ( 14 ) permit towing and static deployment. The device is also designed for a single person construction and operation,
