What make of DH regulator was John Farrar wearing when he pulled Mary Jo's body from Ted's car?
"The diver who collects specimens of underwater life has fun and becomes a keen underwater observer. .. seek slow-moving or attached organisms such as corals, starfish, or shelled creatures." (Golden Guide to Scuba Diving, 1968)
It is interesting we talk about regulator position being so important, yet look how that pack holds it so far off, and how high that diver is wearing it...
