Hi. Please, I could use some help. A succinct answer will be more than fine. Why would a diver use dual tanks? Just extended dive time or for mixing gas? Forgive me, I'm writing a brief article, I'm not a diver, and could use this info for reader clarification. Heaps of thanks! Mike

My bro is a cave diver and he takes the second tank for an alternate/additional supply of air. I suspect that other divers take a second tank so that they can stay down longer. Personally, it's all that I can do to get my hairy a** off the bench with one tank on, let alone two.

1) larger air supply
2) gear redudancy in case of problems like a freeflowing regulator
3) twin tanks tend to be more stable on your back than one large tank of the same volume.

I read on SB that if you don't dive Doubles, you will die.

Dual tanks are generally used for Deco diving. I do know a few folk that use dual tanks because that is how they have set things up, and they can often do 3~4 REC dives off of two tanks...

Doubles offer the advantage of redundancy/backup and more available air. The downside is they are kinda bulky, and you need a bunch of additional gear vs. single tank diving.
