The DIR info I have seen specifies aluminum tanks for OW diving with wetsuits and LP steel tanks for cave diving in drysuits. I have used primarily HP single steel tanks with thick wetsuits and drysuits in ocean diving temps from 60-70F.
What is the DIR - preferred tank material for a single or double tank config for drysuit diving in 50F degree open ocean water on the Pacific coast?
