Hard Hat, Rebreather, and Double Hose Day

Hard Hat Diver looking out at the Aquarium Visitors

          It was a beautiful Sunday the 17 of March, 2002, that the CEDU accompanied the CCED for a demonstration of  Classic Equipment Diving  in the Aquarium of the Pacific.

        It was a special privilege to dive in the Aquarium of the Pacific, and to demonstrate antique and modern diving gear.  Both major tanks in the Aquarium were used.  The 65 degree Blue Cavern Habitat saw divers using all three types of gear.  The warmer Tropical Pacific Habitat saw classic scuba and rebreather divers only, as it was not set up for the Heavy Dress.

        Equipment dived included Heavy Dress (Hard Hat), Open Circuit and Closed Circuit gear.

        The Heavy Dress divers used MK V and Desco helmets.

        The Classic Open Circuit Scuba systems used Double Hose regulators on single, double and triple tank sets.

        The bubble free divers were using both Closed Circuit Oxygen Rebreathers, and Closed Circuit Electronic Controlled Mixed Gas Units.

        Three models of closed circuit rebreathers were dived:  (1) The Prism Topaz, a very capable and state of the art Mixed Gas Electronic Controlled Rebreather, (2) The  FEOR, a depth limited and more simple Manual Controlled Closed Circuit Oxygen Rebreather, and (3) The FEOR Light another Manual Controlled Closed Circuit Oxygen Rebreather, but with an Integrated Partial Pressure Oxygen Sensor and Display which opens the door to deeper depth use.

    Some gear may be old, some may be new, and  some may have been under construction as we dived, but all gear worked as advertised.   It was a wonderful day at the Aquarium of the Pacific.  We are all looking forward to next year.

    A big Thank You to Pete, and all the other Aquarium staff who made this event possible.
