right there is always the danger that you may be killed or injured. No piece of diving
equipment can prevent the possibility that you may be killed or injured any time you
enter the water.

The Kirby Morgan 47 helmet meets or exceeds all performance and testing requirements of all gov­ernment and non-government testing agencies throughout the world. It is approved for use on all
commercial and military work underwater. Only Kirby Morgan masks and helmets have achieved the
CR (Commercially Rated) mark, the highest United States of America rating.
