| Interesting. With my own diving I tend to notice it in stages- at 20m I get the heebie jeebies, usually cos that's when the PPCO2 is high enough from the surface swim/long walk/kitting up breathlessness. I also get some spinny vertigo too. However because I'm expecting it, coping with it is relatively trivial and it's quite enjoyable once you know it's coming. The down to 30+ and there's the warm fuzzy feeling and past 40 things at that stage depend largely on the viz. Good viz then it's still warm and fuzzy, 2 ft viz it's uncomfortable.
It's all about working up to dives. I've already done a whole week's relatively deep repetitive diving in Scapa so the Salsette tomorrow is a dive to really look forward to. However what I've found works well (for me) is once kitted up, have a minute or 2 to relax, do a sanity check on your kit, then jump in to the 6m bubble check, then another pause at 30m to check everything's still ok, then down to the bottom of the shot. At this point I take a minute or 2 to acclimatise, make sure the backup reg is working and let things settle down before heading off for the bottom part of the dive. Works really well rather than bolting off as soon as you hit the bottom of the shot. |
