DIR Details

[Deep Blue]

Chris,

First for those that are not aware, on a set of doubles, I will describe the hose routing. All descriptions are left/right as you are wearing the tanks.

Right post, primary regulator routes straight down behind the wing. BC inflator routed across the back of your neck.

Left post: Backup regulator, running behind your head and over your right shoulder and if not using argon, the drysuit inflator under your left arm, and pressure gage running straight down in front of wing.

Hose lengths are as follows: Primary, 5, 6 or 7 foot hose depending on your needs. Backup regulator either 22 or 24 inch hose, depending on regs being used. Pressure gage, 24 inch, BC inflator hose 24 inches.

The reason that you inflate the BC from the right post is so that the hose runs behind your head, allowing you to hear any leaks. The reason that you don't route the drysuit hose around the right hand side is so that when you use argon and place the bottle on the left side, you don't have a different routing than if you inflate with backgas. (argon is on the left side because your cannister light is on the left) The final reason is, and I hesitate to say this, but it is the truth. You put it there because that is the way you dive DIR, and that is what your team mate is expecting.

If anyone has other questions on why hoses are where they are, just ask.
