Double Oring seals on the battery box (waterproof battery box now too, so strobe is safe from flood), easy to use controls, rugged construction, soft bumper ring around the front. This looks more like what I would have paid $750.00 for last year.

Works with most cameras, digital or analog. Strobe kit includes base stay with lots of different mounting options and also spot to add another strobe, and flex arm with neoprene cover. Reduce backscatter and add vibrant colors to underwater photos. Adjustable output and pre-flash settings. Waterproof to 183 feet (55m).

*Now includes fiber optic link cable*
