<div dir="ltr">Hi Alan,<div><br></div><div>I thought about the fact that the pressure to the inside of the sub would be increasing with depth after I sent the post. Are you also breaking down the HP to LP at the bottle outside the sub?

My bottles will be on the outside and I have two 02 cleaned first stage regulators that will take them from HP to LP then into the sub.<div> I guess the average LP setting is around 150 psi + -above ambient? so I should be able to have a dive shop re set them down to 50 psi? What have others done that have the same scenario and wonder if there are flow meters that can take the 150 psi in?<div><br></div><div>Rick</div></div></div>
