A friend asked me if the Argonaut breathes better than my phoenix. I know its on hear but can't find the thread. Does the argonaut breath easier/better than the phoenix or cyclone? Are their any mechanical advantages over the phoenix/cyclone?
By the way, I try to tell people that double hoses are not out dated and are still currently in production. But I have yet to meet a dive shop owner that is teachable. They just start spewing about liability and look away from me.
