Difference between wreck and cave diving?

[DCBC]

Anyone have a regulator or any air integrated device freeflow while in an overhead environment?

Yes, it's commonly experienced by divers at one time or another, while ice diving.

I got the impression (especially from reading both The Last Dive and Shadow Divers) that the two activities evolved separately, and thus had some differing approaches to the same issues.

Not just that, but the same activity evolved separately in different areas. I'd been penetrating wrecks for many, many years before I'd ever heard of progressive penetration.

... Another is the approach toward finding your way around. Wreck divers used an approach called "progressive penetration," whereby they got to know the wreck a little at a time. Cave divers ran line and followed it back out. It is my understanding that cave divers moving to wreck diving brought with them the use of a line for navigation...

The progressive penetration vs line argument was put to rest forever on the Spiegel Grove in March '07. Use a line.

My compass works better in caves.
