Post by MarioHello,
Can any one tell me if the Suunto Stinger shows the residual nitrogen
time ? if it does what are the steps to read it ?
Suunto doesn't use RNT like the PADI DSAT tables do. You only need RNT to
determine Adjusted Max Bottom time for a given depth. Suunto skips RNT and
just shows you the new bottom time through the PLAN mode.
But if you'd like to see it you could:
Go through the PLAN mode (before diving) and make a list of Suuntons max
bottom times for a given depth.
For my mosquito set at A0 P0 Air the values are:
30 --- ( some big number )
40 120
50 69
60 51
70 36
80 28
90 22
100 17
110 13
120 10
130 9
140 7
150 6
So lets say you do a dive and come out of the water. You won't be able to
go into plan mode right away until the computer closes out your current
dive. ( Reentry within a few minutes is considered the same dive profile.)
Once your in you go plan a dive for a given depth. For example 60' it says
you can dive for 40 minutes. That means you have an RNT of 11minutes for
60'. Lets say you plan for 50' and it says you can dive for 50 minutes.
That means you have a RNT of 19 minutes for 50'.
Also if you have the PC inteface kit you can download your dives and see
your RNT expressed as tissue compartment %'s. This is a better way to look
at it. RNT's are useful in the sense of teaching a diver that he his dive
planning must accomodate the fact that he has residual nitrogen in him, but
other then calculating adjustet bottom time and total bottom time the RNT is
reallly not useful. Since the computer does these calcs for you and just
shows time remaining, I wouldn't worry about it.
