Argonaut Mix-mount or Tri-mount… as opposed to side-mount

    I thought I was learning a new term or piece of equipment.

    I need to see a good picture or schematic of this...

    edit: okay, looking at the head-on picture. The two lines exiting the slung stages appear to have shut-off and quick disconnect fittings on an low pressure port, an octo (stored) on another. Those wrap behind you and are fed into the LP ports on the Kraken.

    Similar to feeding to a hookah port on a vintage DH?

    I will try to post some pictures of the hardware in a couple of days.
    I can draw a schematic, but honestly, it is really so simple that a schematic would probably make it look more complicated than it really is, and it would take me a lot longer to draw it than to just take some pictures.

    Again, the more time consuming is going to get my trim, weights and tank location just right. Those two little tanks are very heavy. I was very over-weighted. The cylinder on the back is just an AL30 which is very low profile and relatively light.

    Here are some pictures showing the hose connections.

    I mounted the Argonaut regulator on a Steel 72 without a backplate or BC to show the hoses. The BC just tucks behind the regulator just like I always set it up.

    Note: I am using yoke tank connections, but I do have DIN fitting for the Argonaut and the Conshelf and those valves are convertible, but I just like yoke connections. I can switch them later if I want to.

    This looks like a lot of hoses, but they are all tucked under the two side cylinders. They are very streamed-lined.

    Here is a picture of the regulator and the BC together. My back gas makes for a nice compact kit.

    I'm thinking how awesome a set of LP50's side mounted with an HP80/MP72 on the back could be....

    Thanks


    The combination of cylinder selection would be totally up to the user. There are a lot of possibilities.

    I personally like using what most would consider as a pony bottle for my back gas/ regulator support. It is very light and compact. I like how streamlined it is and the small diameter tank places the regulator right on my back.

    You can see in the last picture below that the regulator sticks past the backplate. I can barely feel it touching my back, but it does guarantee that it is as close to my lungs as possible. This is already great breathing regulator, but this makes it just perfect. The only way to improve its breathing performance is to have surgically implanted. :)

    The three cylinders I am using are small. The aluminum back-gas is an AL30 (diameter = 5 1/4”, by 20” tall).
    The steel ones are 61 cuft at 3300 psi (diameter = 6”, by 22” tall). These are good testing cylinders up here because they are very heavy in the water.

    As I mentioned, this is more complicated than a single tank, but it does open the door to many possibilities. It is just another set of tools that can be used for some challenging dives or just for fun. :wink:

    Here are some pictures of today’s dive.
    I made some adjustments to the side tank location and to my weights. I am pleased with the outcome. I was very comfortable with my dive kit.

    Here is a short video from yesterday.

    I was checking to see how well I could back-kick with the side tanks and I also tried rolling to see how the tanks would behave at my side. It all worked out well. The only issue I had was a small air leak from my right tank valve. I just need to replace an O-ring on the convertible DIN valve.

    Thanks to John for taking the underwater pictures and video.

    I am feeling really good that I picked the same Conshelf 14 1st stage and using 109's as the seconds on the side mount tanks.. If Luis picked it, You know it's a great setup.. :wink: And thanks for the pictures... It'll be a help with working out my kit..

    And I still need the 19cu as a back up as the 40's will not have a gas that is use able on the back end of the dive..

    Jim...
