“Dirty Harry” Case Study

“Dirty Harry” Case Study


The “Dirty Harry” Contaminated Water Diving System is designed to provide a safe and efficient surface supplied system which minimises the risk of contact between the diver and the water in which he is diving.

The basic method of achieving this is by providing a closed circuit breathing system whereby the diver’s gas is returned to the surface and exhausted to the atmosphere rather than exhausting into the water.

As well as offering respiratory protection, a heavy duty rubber membrane drysuit which attaches directly to the helmet provides the diver with full skin protection.
