HP and LP Hose Routing
Learn how Bahamas Underground proprietor , Brian Kakuk, recommends routing SPG, Drysuit and BCD hoses.by Brian Kakuk
There are a lot of great ways to run both HP and LP hoses allowing for relatively snag-free configuration.
HP 6 inch hose
The first stage can tilted so that the HP hose runs backwards (toward the valve handle when using “mirrored” valves), at about a 45 degree angle from the centerline of the tank. When the tank is mounted on the side, the gauge ends up lightly pressing against the upper chest or shoulder depending on the diver's torso length. Tilting the regulator body also keeps the gauge hose from turning into "antennae" and plowing the bottom in close quarters.
Short torso divers (women and smaller guys) will end up having the gauge right near their cheeks in this configuration, and they will bump into them every time they turn their head. Smaller divers are better off with the HP gauge hose running down along the tank on a slightly longer hose (9 inch).
Stowing the gauge along the tank with the 9 inch HP hose also works out well for those of us whose eyes need a little more distance to see the increments and numbers, and are dragging our heels on getting lenses for our masks such as the Dive Rite ES125 reader lens mask.
LP inflation hoses (BCD and Drysuit).
If diving wet, running the LP BCD inflation hose under the harness shoulder strap will allow it to stay close to the body and fairly snag free. I run this hose from the left tank under my left harness shoulder strap near my waist across my chest to the BCD inflator. I use both Armadillo (old and new style) and Dive Rite Nomad (old and new style), and running from the left side works well with all models. The main objective here is to end up with the BCD inflator above the nipple line (straight line drawn between the nipples on your chest....I know sounds funny, but it's important). If you can end up with the inflator in the center of your chest, two or three inches above your sternum, then the inflator is now "no-handed" and can be reached with either hand if needed and is very snag free.
Much of this is easier to explain in person and is certainly not my intention to steer the reader away from getting one on one training from a certified and qualified (there is a difference) side mount diving instructor.
