Here is a link to the Banjo Ad: www.vintagescubasupply.com/banjoad.jpgHere is my question: Cousteau designed a little known follow-up to the Conshelf III undersea habitat. This habitat was unique in that it was completely mobile and self sufficient. It was basically a submarine that was capable of landing on an underwater site and staying there until its mission was complete. It could then travel on to its next location. It made it into production and was about 50% complete when funding was cut. What was the name of this craft? Hint: It was not Conshelf IV -Ryan

Just playing makes you a winner but your answer does not -Ryan

I couldn't find the answer, but this site says Cousteau originally planned 6 habitats. What was really interesting to me is that Conshelf II is still at the site, and available for divers to see, fourty years after it was used by Cousteau. I had thought it was removed. Here's the site I found: www.beyondmagazine.co.uk/travel/conshelf.htmI cannot spend more time on it, but hope someone will find the answer. John

The Conshelf II site still has the sub hanger and a couple small structures but the house and deep cabin were removed. Here is a hint: The project was named after a spider that lives underwater by breathing air stored in a silk pouch -Ryan

Argyroneta?
Name of the spider is Argyroneta aquatica so I just dropped the aquatica.

Wasn't it actually spelled Argyronete I think that JohnA was close enough. If my answer is correct then I'll pass to him. (If I'm wrong I guess it doesn't matter... )

It appears you are both right "This spider is one of the only watery spiders of Europe. Indeed, if it doesn’t live completely under water like the argyronete (Argyroneta aquatica), it passes most of its time in an adult state on its surface." Source: www.treknature.com/gallery/Europe/France/Central/Limousin/photo16285.htmCousteau’s sub project was the “Argyronete” Cousteau’s project was scrapped about 1972 but was reborn in the form of the SAGA submersible. The SAGA followed closely to Cousteau’s vision in both form and function. It was built using the hull from Cousteau's project that had been sitting in a shipyard in France since the 1970's “Developed in France by IFREMER and COMEX, SAGA is the first prototype of a new generation of industrial submarines capable of carrying out underwater operations using divers or robots at close proximity to the work site without surface assistance. SAGA (28 meters long, 550 tons submerged displacement, 6 crew members) has a hyperbaric compartment for 4 to 6 divers. Several important innovations, in particular with regards to energy, give SAGA an exceptional autonomy, essential for performing deep underwater operations. The submarine was launched in October 1987 and has just completed to three-year qualification programme. Since May 1990 SAGA holds the world record of the deepest (-317 m) diver lock-out operation from a submarine.” Date publication: 1990/12/01 Auteur(s): J MOLLARD , Didier SAUZADE Nom du congrès: Intervention Sous-Marine ISM 90, Toulon (France), 3-5 Dec 1990 Source: Actes de colloques.

I win the "close enough" award, so here is my question.
Who manufactured and what was the product name of the first production dive watch with a helium expansion valve?

I think this was the Rolex Submariner, which introduced the Sea Dweller 2000, which was equipped with a helium gas escape valve, and waterproof to 610 meters. I took a chance on it being a Rolex, and looked over their website. Their website is fascinating, and vintage divers should check it out even if this is not the correct answer. Here's the website (check out the link called "Collections" in the upper left corner, then choose "50 Years of Submariner": www.rolex.com/en/Is this the correct answer, JohnA? John

Very close, but no. The Rolex Submariner with the HEV was not for producton, it was just a test bed, mostly given to the COMEX guys.
Rolex worked with a second company and they shared their data, it is this second company that got the watch to production and sale to the general public first. Although first to production, this watch is exceedingly rare and at this time only 3 are known to exist. Rolex with the Sea Dweller ended up being a far superior watch.
Hint: this watch company did not sell directly to the public, but thru a large dive equipment company. They also hold the US patent on the HEV.
