Great Lakes

[rhwestfall]

My Subsurface profiles are better to see, but I can't get to them right now...

These were "Techreational" with a minor deco:

dives were done on an HP100 twinset, though I might (likely) have transfilled between.

20 - 25 minutes of bottom time each on 28%, and a deco on 50%.

Dive #2: Crystal:

Dive #1: Tradewind:

You can see where deco hits, and as said, 15-17 minutes and up is a nice recreational profile.

They are really worth seeing!

YMMV.

Thanks al248005 and rhwestfall! Very interesting material. I'm thinking about trying to get to a few shallow Great Lakes wrecks this summer (along with a fair amount of quarry diving) -- maybe Nordmeer (looks big and shallow) or something out of Erie, PA or Sanilac, MI. Maybe in a few years after doing the advanced certification and drysuit, I'll look into diving these. Some of the most interesting Great Lakes wrecks seem to be around the deep end of recreational (80-120 or so). I appreciate the information.
