Description
Double Tank regulators sets typically employ a Hogarthian style equipment configuration, or the Hog loop. It is founded in simplicity and minimalism. In essence, you remove potential failure points and what you do carry is kept as streamlined as possible. The man who pioneered the configuration is William Hogarth Main, co-founder of the Woodville Karst Plain Project (WKPP) deep cave diving team. His first cave dive was in 1969 and he is still diving them safely today.
In this configuration, the short hose measures at 55cm and the second stage is kept on a necklace. The long hose measures 210cm in length and routes under your right arm, up across your chest, and around your neck to your mouth. Any extra hose length is typically stowed under your waist strap in front of your right hip. A bolt snap will typically be attached where the long hose meets the second stage so it can be clipped to your right shoulder d-ring when not in use. In an emergency, the long hose second stage is donated to your buddy in need and the short hose second stage is transferred to your mouth. The advantage to this configuration is the extra length of hose that can be donated to a buddy, allowing you to swim in a single-file line while sharing gas. This configuration has become the standard for technical diving.
