Intova Waterproof Strobe ISS 4000:
Sleek and powerful, the ISS 4000 waterproof strobe provides great flash performance in a compact size.  4 preflash settings allow the ISS 4000 to work with virtually all cameras. The power knob  adjusts anywhere between 10-100% for precise output power. Recycling time between flashes is blazing quick.  The diffuser is now included with the strobe, ideal for close-up underwater photography.  (Important: to maintain waterproof seal, be sure to clean and remove debris from O-rings and lightly apply silicone grease before use.  Click to go to Lighting Systems/Strobe FAQ for more information on maintaining your strobe.)  Underwater photos by Rocio Gajon using Intova’s ISS 4000 waterproof strobe.
