rescuediver009:oooooooooooo goodie! Are we gonna play the name game?
Scubapro - regs
Halcyon - maybe wing?
Oxycheq - backplate harness and maybe wing
OMS - stage bottle with regs?
DUI - suit obviously
Terkel - Light
PST - tanks
Perhaps I should have added more info, but you are on the mark except for Halcyon = back up light and OMS = spg. Scubapro is also for jet fins, regs. and bottom timer.
