Erik Il Rosso:What a day !!!
The dive was pretty simple, 10 minutes at -40 metres, resurfacing and switching to O2 at -6 metres, my instructor wanted to see if I could follow the specified run time...
I'm surprised the first dive was so deep. My deco class involved six or so simulated deco dives to ensure we could deploy a DSMB and do stops at various depths with and without the buoy (and without mask) without any problems before we actually went near deco limits for real.
