DIVI Flamingo: what is the present condition of dive pier? Does anyone know the present condition of the dive pier at DIVI Flamingo? How are the repairs coming? Are they working on it? Any predictions of when will it be back in service? If dive pier is still not in working condition...

I am very sad to share this news. Robert Couvillon passed away peaceful this afternoon, after an illness. He will be missed by many here. Deepest condolences to his family and friends.

Argonaut Kraken question The question has been brought up about the future of the Argonaut Kraken. It is too early to talk about any new built units. I honestly don’t know if anyone else will be interested on taking on “new-production”. I own the regulator design (except for the label) and I...

Deep dives with Argonaut Double hose General dive descriptions: I just got back about a week ago from the Dahab in the Red Sea, Egypt. We did a series of deep dives with two of them in the Blue Hole just north of Dahab. One dive was to just under 210 ft of depth and the las t one was to 305...

I am sorry I don’t have a better picture, but it is a fairly distinctive front cover. I am trying to identify the make, model, and maybe when it was around. Based on some of the other equipment this diver has, I am thinking it is possibly an old Cressi octopus, but I have not found any similar...

I would like to know the O-ring size and preferred O-ring type (material and durometer) used on the aluminum arm ball joints with clamps. I have Kraken aluminum arms with ball joints, but I would think they are interchangeable. I have heard them referred to as 1” standard ball mount. Is that...

After five and a half years and about 500 dives I decided that it was probably a good idea to rebuild my number 1 Argonaut (original prototype). The only indication that service was probably a good idea was some dark coloration on the inlet filter and some minor corrosion. I was not very...

I realize that the published maximum rated depth is 148 feet. There is no published safety factor. So I am interested in any actual experiences that others might have had. I am only planning on possibly going down to 160 feet or 170 ft. What are the probable failure modes? The loss of push...

Argonaut mix-mount… a variation on side-mount Here are some pictures of my second dive with this configuration. I am calling it mix-mount because it uses some side-mount components, but I am also using a 30 cuft pony bottle on my back as a mount for my double hose regulator. The regulator also...

Argonaut Mix-mount or Tri-mount… as opposed to side-mount The new side mount configuration has been talked a lot for technical diving and I can see a few situations where it can be beneficial. I am not interested in getting in tight spaces, but I would be interested in getting qualified for...

Note: In this thread I am trying to collect all the technical information on the DSV that I have posted in different places and locate them in one place. DSV (Dive Surface Valve) style of mouthpiece Features: 1) Simple design with minimal number of parts to increase reliability and keep...

The video below is a spin-off from one of the many analyses I did during the detail design of the Argonaut. This animation is a simulation of the mechanical motion of the parts. NOTE: THIS VIDEO IS NOT A REPRESENTATION OF A BREATHING CYCLE. It shows cycling the demand valve into a fully open...

Argonaut Kraken specifications Subject: Project Argonaut Totally new, vintage style double hose regulator. Note: NO Aqua Master or Royal Aqua Master were harmed, sacrificed, or cannibalized for this project… Ok, the cans were temporarily on loan, but all parts are now new. Cracking effort...

I am thinking about getting one of the visual indicators like the one in this link: August Industries - Visual Indicator August Industries - Visual Indicators I have two options for the actual indicators disk. They both measure relative humidity. One reads 20, 40, 60% relative humidity and...

Phoenix HPR for sale I never thought that I would say that I have too many regulators, but it seems that I need to reduce the herd. Here is my #3 Phoenix HPR. You can see the number stamped on the hookah port adapter (yes that is the only way I can keep track of all of my Phoenix HPR, I have...

I just rebuild an Aqua Master for a friend of mine (who coincidentally is a rep for Aqua Lung). It has been a little while since I worked on a non-balanced Aqua Master so I decided to publish some of the IP versus tank pressure data. I have taken this data before, but not as precisely and in...
