Dive 2
After your surface interval of 1 hour, you are ready for your next dive.
After Dive 1, you were on PRESSURE GROUP C, so you will need to select Pressure
Group C for this dive. This dive you plan to stay for 45 minutes at 60 feet.
Entering the data on DivePlanner you get:
You cannot stay for 45 minutes at 60 feet on a no decompression dive. Maximum
allowable time is 41 for a no decompression dive. So you will have to alter your
bottom time for this dive to 40 minutes.
As you can see, the Residual Nitrogen Time (RNT), Actual Bottom Time (ABT) and
the Total Bottom Time (TBT) has been computed. Take note also, now you need to
make a safety stop at 15 feet. It's getting late in the day, so your planned
surface interval for this dive is 30 minutes. After this dive and surface interval,
you are now in PRESSURE GROUP N.
REMEBER: this is not intended to replace your dive computers. It is
always better to check your dive plan against a dive table for extra safety
precaution.
