Dear scubaboarders,
There's alot of anecdotal evidence and info to be found about detuning your regs for really cold water diving. Usually it consists of both detuning thé first and second stage.
However I can't really find any real literature on the use of detuning your first stage for cold water diving.is this solely so they drop from 8-10 bar to ambient would be less? If so is the drop from tank pressure to 9 bar less significant then?
Wouldn't the temperature drop be even greater from tank pressure to first stage pressure when detuning a first stage?
How does this work exactly, and is there any significant proof that detuning a first actually helps with cold water reliability?
I'm not trying to stir up a debate wether or not this is useful, but i'm more looking for reliable info on the why and if.
Kind regards,
Joris
