Hollis DC2-212 - Dive Right In Scuba - Plainfield, ILI e-mailed Hollis today asking them about the adapter and/or the longer hose option. We'll see what they say. I am starting to research regs. I am almost convinced my reg will become a backup/stage reg. I am not into buying a $300 second when I can get a decent reg set for $400. This single setup is going to be used primarily for travel so I don't need to replace the Hollis with another Hollis. I'd still like to know that there are other options. Hopefully I'll hear from Hollis or Nick will respond here.
$290 for the whole reg, I emailed them and they said the hose can be replaced with a stock miflex one, so any hose should work on this version. I don't know if the internals were redesigned or if there is just an adapter that they use now though.
