Ultralight double handled tray. Original purchase price $165. For sale $60 + shipping from California (originally offered at $90)
Ultralight says it works as a double handle for most digital housings, including Olympus, Canon, Nikon, Sony, Minolta, Casio, Sea and Sea, Fuji, Panasonic and Sea Life. I used it with a Nauticam housing.
