Underwater versatility is the key to the MINIWAVE II. Two modes help conserve power and an auto backup filament ensures safety. The Miniwave II now incorporates the same power up feature of our popular Shockwave II. By flipping a switch, you can choose the required amount of light and power up from 3.0 watts to 5.8 watts. The unique switch system also offers the added security of switching to an alternate bulb filament in the event the filament in use burns out. The Miniwave II is compact, lightweight and easy to operate. It will satisfy your every need and be there when you need it.
