I’ve been an open-water and drysuit instructor now for 20 years, and in the past two years a black-water/contaminated-water search and recovery instructor. In the next few months I’ll be adding a double-hose/vintage scuba instructor rating to my teaching repertoire. Much like PADI and SSI, Scuba Diving International (SDI) also allows an instructor to create their own specialty. There aren’t many who can teach double-hose (regardless of agency) so I’m fortunate to be training under a Vintage Specialty PADI instructor. Once the internship is complete I can create my own course. When teaching double hose, I’ll need regs so I had these restored and built by Jerrie Struble at Diver Down DHR. They’re all 1959/‘60 serial numbered cans and I went back with the correct color combo hoses and mouthpieces for the era, as well as sourcing the original 1st gen USD plastic hose clamps from The Scuba Museum. In addition to teaching in-water technique, a portion of my course will be on the historical preservation of vintage diving gear. .jpg) The regs will be dove with 1959 steel ‘72s and I’ll finish outfitting the remaining two cylinders with bands, and cotton webbing harnesses by A&D Adventures. This will be phase one of the course with the second phase using a modernized double hose with an upgraded, multiport first stage reg.  |

Well, it's looking good for your double hose course. I'm intrigued, so please keep us informed about how it is received.

Really cool. What regs will you use for the second phase? Or will it be these with banjos and hookah port adapters?

Believe it or not when I took my open water course in 1975 we were taught double hose techniques. Nobody used a BC or SPG in the class I took.

Jerrie is working on three more custom regs that will use his Phoenix-like 1st stage. Those will use a Scubapro SPG and something like a Scubapro S560 as back-up. |

Believe it or not when I took my open water course in 1975 we were taught double hose techniques. Nobody used a BC or SPG in the class I took. I certified 9 years later in 1984 and there wasn’t a double hose to be found in the shop I trained through. I didn’t know until years later that the guy who owned the shop hated them. Said it was like trying to breathe through a plastic straw. That stuck with me and was my impression of double hoses until I got my first one a few years ago. Now I’m like what kind of broken down, detuned double hose had that guy used to give him that impression? Either that, or he didn’t think they were that bad but just wanted to push the new stuff. You were fortunate. |

I think you are doing a great thing! It looks like you are going to have a great set up. How many sets are you trying to have in your arsenal ?

I think you are doing a great thing! It looks like you are going to have a great set up. How many sets are you trying to have in your arsenal ? Right now just these three. One I will use to teach with, and the other two will be for students. I think a 2:1 student to instructor ratio is about right until I see how how things work out. I’ll add more if I need. |

We need to see photos of the “phoenix like” regs. Can’t dangle a statement like that without some photos!

We’ll, I’m now an officially certified Vintage Equipment Diver. Dave Danielson put on a great class and it gave me the class structure to create my own program through SDI. Plus Dave has a great collection of vintage regs and he lets you try any of them that you want. .jpg) |

You were fortunate. Here in Massachusetts we got the "Can't get parts for those double hose regs anymore". Being young and expecting the LDS to be truthful with me I figured OK, little did I know Nemrod was not only making parts but was still selling the Snark 3. In my opinion the certifying agency's pushed to get rid of double hose regs because it was easier to outfit a single hose with an SPG and LP hose for a BC and Octo. It was around the same time the SPG, BC and octo became mandatory that our double hose regs fell out of favor |
