The Scuba Museum is very please and excited to have in the collection a very rare Argonaut Prototype regulator from Vintage Double Hose. The Argonaut has now been with us for over a year now and it has dived depths deeper than 155 feet. Below are some updated photographs of the 3D printed cans in black with a preproduction label. Also note the prototype heavy yoke with unique yoke screw. This regulator breathes as well as it looks. This Argo has also been dived in the Chac Mool Cenotes of Mexico as of 2013. Needless to say it turned many heads at the Mayan dive site.
