Hello,
I plan to make a wreckdive tour in shallow water. The deep is round about 35 meters bottom (round about 105feet). I plan to use Nitrox for the dives but I'am not sure about what best for me.
I have different options. The simplest option is to use EAN32 and the NOAA table for that gas.
Another option is to dive at 1.6PPO2 with EAN35 and calculate the EAD (it's round about 27 meter) and to use a air decompression table like US-Navy.
This looks good to me, because for a 30 minute dive at 35 meters I figured out a no decompression dive. (So I remember...the data is still from my memory, I've calculated it day's before)
The next option is to use different O2 mixes. EAN32 as bottom mix, EAN50 for the ascend and EAN100 for decompression. This will result in a 30 minute dive at 35 meter, an ascend with EAN 50 with two deep stops of 2 Minutes and a complete ascend time of 12 minutes to 6 meter (18 feet) and there a decompression for 7 minutes with EAN100.
I've calculated this for a bottom time of 40 and 45 minutes (with Zplan) and this looks good to me.
But when I use Zplan I only make one dive a day and now there is my question:
Should I do one Zplan calculated dive with a bottom time of 45 minutes with EAN32,EAN50 and EAN100 or should I make two dives one of 30 minutes with EAN35 and two hours later a second 30 minute dive with EAN35 and calculated with the EAD method using the US-Navy tables?
Any suggestions whats best?
