Sealed diaphragm, swivel turret with 5th port like everyone said.... really can't go wrong.
Hog or DR will be less expensive up front, but Deep 6 signatures include the 1st rebuild kit with each reg, AND the 1st rebuild is on them when you're ready (have to pay shipping one way). In that sense it's either a little less or just about even with the others.
Deep 6 also will give you free rebuild kits every 2 years / stage if you take their rebuild class. No one else does that (that I'm aware of).
There's plenty of regs that make sense if you never want to rebuild anything... there's only that makes sense if you think you eventually will. I took the Deep 6 class @ 25 dives in and I love my regs.
Out of all the manf listed in this thread you can really only call 1 direct.... I'll let you guess which one!
Is there an echo in here? I feel like we just had this thread, lol
It's all good.. I know the threads get lost...
