Sub Gravity H3 or Petrel

[SubGravity]

The H3, as far as I know, isn't a CCR capable unit. Big ding for me, but maybe not for you.

Just FYI - it does come enabled with CCR mode (constant PO2) and trimix

We have a few H3s being used and abused in the caves of FL this week and next as 2 CCR Cave courses are being conducted simultaneously. We will ask a couple of them to get on here and post a report when they can.
