Adding artificial light to underwater photography is the key to better Image. Having the best platform to help provide that lighting is as important as the artificial light itself. Having the ability to use an external strobe/video light can drastically improve the quality of your underwater photographs. Being able to aim that strobe/light exactly where you want it to illuminate your subject takes the use of a strobe/light arm. The Big Blue Accessories Series employs the latest designs that cater to different photographic and video systems. By utilizing the best possible materials on the market, such as T6061 grade aluminum, stainless steel, fiberglass reinforced resin, etc. Big Blue's series meets the demand for high quality with affordability. Compact version of Bigblue's popular mounting tray has a 1" (2.5cm) ball at the top of the arm and comes with an anodized aluminum Go Pro adapter. All adapters and clips are sold separately.
