These are pricey new but you can get them used on eBay. I was operating all four of my Minn kotas 101 off this single regulator. It was a special ss pressure reducing/pressure releasing regulator. I had it installed on my last Florida dive which I went down about 100 ft . Unit worked fine. My first failure was on Flathead lake expedition in which one of my aft thrusters flooded. After that I switched to oil compensation. Alec is using same regular on his articulated arm and not the thrusters. He felt issue with the regulator was that the port for releasing pressure on ascent was too small. I believe he has addressed this by adding a pressure release valve or OP valve. He can elaborate more on his current strategy.<div><br clear="none"></div><div>Cliff<br clear="none"><br clear="none"><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br clear="none"><blockquote type="cite">On Jul 31, 2023, at 9:14 PM, Alan James via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br clear="none"><br clear="none"></blockquote></div><blockquote type="cite"><div dir="ltr">John,<div>I am happy with both air & oil. </div><div>Am intending to fill my thrusters with oil, but have the oil pressurized off my air comp system.
