The SCA-150 is a heavy-duty pressure gauge ideal for divers using a wrist-type dive computer like the IQ-650, IQ-750 and IQ-900. The console provides continuous air pressure and temperature in a low-profile rubberized boot. The pressure gauge features a luminscent light storage dial that is highly legible in dark or low visibility conditions. The entire face glows bright enough to make it ideal for night diving or diving in dark areas but contains no radioactive materials.
