Did two today, first dive switched between the 370 and 420 both on a titanium MK11. The 370, once tuned is as good as anything I have ever tried, truly a high performance reg. Second dive put the 420 on the long hose and only used it, not really impressed with only a minor tune it cracks very easy put I had to pull hard to get it to feel like it was ready to go and move air, otherwise I would say it feels like a double hose, my guess it it’s in the lever, it gives the same impression if you screwed the orifice in to far on a straight through “S” series and dropped the lever height, it drying tonight so I should get some time tomorrow to open it and see how the lever sits.
 
Yah, I wish I had managed to get the 370 regs I was trying for... Maybe next time...
 
Heading off to Key Largo tomorrow for a week on the 420. We'll see in a week if I still like it more than you guys seem to...

What first stage? Which wreck is the 420?

Nice jealous who you diving with what outfit? Was there a couple months ago.
 
Big runny smelly poos.

Strike 2.

Leaked the whole dive.

I'll put it back on a gauge when I get home and see what's what. Venturi switch did nothing even though it's increasing cracking pressure. I've it set to 1-1.1" even though that's lower than spec with Venturi on max it should not be leaking.

I can only assume the lever is too high. It's at about 1/2mm below rim of case.

Still find the bubbles a little irritating, vertical it's a mikron.

It does breathe nicely though.

Will post back later.
