Why not just go to God's Pocket?
Bit late for that. Horses, open barn doors, etc.
Assuming that the site can be found again now I would get hold of Bill Coltart at Pacific Pro Dive in Courtenay or Liz Tribe from Nanaimo and see if one of them could put together a tech team within the next 3 or 4 weeks to try and retrieve the gear. Most of the stuff will still be useable. Pay for their expenses and it would be cheaper than having to buy all new stuff, especially if the group all chips in.
