COMEX PRO is a highly experienced company engaged in design and manufacture of individual equipment for
professional divers, hyperbaric safety equipment, hyperbaric treatment chambers and remotely operated
vehicles (ROV's).

COMEX PRO is one of the world leading companies in deep diving technology. As from 1963 they constantly tried to reach greater depths. In 1977 a team of COMEX divers went down in the Mediterranean sea to a depth of 501 meters. The divers were breathing heliox. The divers had no problems working in this depth and returned to the surface without problems.

In 1988 a team of COMEX divers went down in the Mediterranean sea to a depth of 531 meters. The divers were breathing hydro-heliox (a mixture of hydrogen 49%, helium 50% and oxygen 1%). It took them 8 days to compress and 18 to decompress ! The divers had no problems working in this depth and returned to the surface without problems.

In 1992, another test in a COMEX tank called HYDRA 10 took divers to a depth of 675 meters after 18 days of compression. They were breathing hydro-heliox. One of the 3 divers stepped over into a smaller tank and went down further to 701 meters. He had no problems in this depth. It took them several weeks to decompress. Are these guys something or what !

Comex Pro helmet.

The Comex helmet below is the Comex X-Lite 2 with the T8 regulator. This helmet with a large metal regulator was designed primarily for air diving. The
Comex helmets have essentially the same shell and side block but the main difference is the type of regulator (air or reclaim mixed gas ), gas reclaim
attachments, the placement of the communications whip or pigtail on the left or right and the placement of the water dump valve, again on the left or right.
