Twin Tanks Training

To use twin tanks do you need any special kind of training?

It is helpful to get training to set your rig up correctly. Learning and practicing the skills to use doubles to their best advantage requires instruction. This is all part of the basic training you would get in a Decompression/Advanced Nitrox class.

"Training" isn't necessary exactly, but what IS necessary is to have someone experienced help you out.

You need someone to show you how to set up your regs, where and how to route the hoses, how to do valve checks, stuff like that.

This can come from an instructor but it doesn't need to. Oftentimes intro tech or cave classes provide instructiono on doubles.

PADI has a discover tech which will introduce you to doubles in a pool environment. It will go over valve shutdown, long hose use, etc. Might save you some $$$ if you can't afford a full tech class, but want to dive doubles in recreational limits.

I actually had my doubles in the water for the first time last weekend.....the guy I was diving with? My course director. I told him I wanted to take his tec deep course a few months ago. He's been helping me get my rig together since then. They are definately a different feeling from singles. He said after a dozen or so more dives with them, THEN we can start the tec course, as long as I'm comfortable with them. There is something to be said about developing a relationship with your LDS.

The 1st dive I did with doubles, was uncomfortable, now they feel normal. I didn't do any formal training but that first dive was with an instructor I know. My set up was done using common sense, photos available on the web, and tips from other divers. I'm still making monor changes.

I did my first confined water session in doubles last night. Didn't see anything too different than my singles setup. Maybe I'm just dumb.

There really isn't anything different. What is usually noticed is the extra negative wieght from all the extra air. (For my 104's its 12-16lbs depending on the fill pressure). That overwieghted means lots of air in the BC and drysuit which means lots of change as you ascend and descend. Most new doubles divers do not add enough air in the first part of the descent and end up extremely negative. (think face plant)

Personally I prefer doubles to singles.

Depends on the doubles. Single anything to double 104s is a big change..

try spinning over onto your back with your 104s on, youll realize real quick you wearing them
