Most folks seem to run an S600 off of one SP's piston first stages. Conversely, I tried running it off from a MK18 diaphragm 1st stage and have had similar problems. I was never sold on running a piston reg in the Great Lakes, with all the particulate in the water. It is possible, as Genesis states, your piston 1st stage may have froze. It may behave much differently than a diaphragm 1st stage. One thing I will note, the S600 was much worse when already wet from a dive.
I hate to tell u this netmage, but I had the excellent tech at our LDS tweak and fiddle with that reg multiple times. It just isn't a deep and cold reg, that's my opinion. This is based on seeing and hearing of multiple people with the same problems. I know I have had great luck with the Poseidon Jetstream 1st stage coupled with Poseidon's Odin 2nd stage primary and octo. They have taken me places the S600 hasn't. I have heared good things about Apeks. Anyone else know anything on those?
After thinking about it won't be hooking up an Odin to my MK18, with the S600 as an octo. The slightly higher IP with the S600 would be suicide. Probably buy an another set of Odins and hook them up to the MK18.
