There are no videos on how to attach HP and LP hoses to an Argonaut as far as I know.....I would 2nd the idea of reading most of the posts in this section and I'm sure you will get a lot of good information. If you have a specific question please ask as we will be glad to help. The Care and Maintenance guide on the main page applies to the Argonaut as it does any other double hose. Below is a link to a PDF I made about the correct placement for your Argonaut or any other double hose. This is very important to follow!
Reading all the posts regarding getting started in double hose diving and double hose diving 101 are a great start too.
Servicing the Argonaut is not difficult and anyone who has experience servicing Conshelf or Titan single hose regulators would be able to service one. Argonaut Kraken regulators are very reliable and with proper care they will go many dives between service.
We do have a member on the forum named Russ who is over in your area....Hopefully he will post a reply as well.
Doing it right should include some common sense, not just blindly following specs and instructions. .Gary D, AWAP on SB
