CNS Loading/tracking multiple dives?

indeep · September 30th, 2006, 05:18 AM

Hey all,

I wanted to get some insight from others on their ways of tracking CNS, whether it be from your personal experience and/or the instruction you have had. I am specifically looking for info on doing mutilple deeper deco dives per day/week.
What were you taught about the CNS % clock?....and how to track CNS%?
What is the maximum % on a daily basis for you?

Please detail any info you can.

I was having this conversation with a team member of mine the other day, and wanted to see what everyone else was taught/doing.....

Thanks in advance.

Hi,

If you stick to standard gases, depths, ascends and deco procedures with the corresponding gas breaks and minimum surface intervals you will be fine for the type of diving you can do on normal OC dives with one deep stage and two deco gases. Probable the same for RB80 rebreather diving.

Anyone else have any input on this subject?
I'm also interested in this as well. Multi day diving (32% back gas, one deco gas -100%, no stages).
It looks like (from the one reply to the original post) that it can be disregarded.

From what I remember from last week (which isn't much

), you can ignore it at a Tech 1 level.

for standard gases...

For all practical purposes you can ignore the CNS clock since your single exposure is 200ish minutes and 24hr exposure is 240 minutes. Even 3 Tech1 dives (using 50%EAN) per day won't get to this level.

For O2, at a pp02 of 1.6 you have 45 minutes. That's alot of O2 time.

CNS loading does not accumalate day to day like OTUs. (which you can also ignore for most reasonable exposures like ~4 rec dives day or 2 x tech)
