ASCENDING TO THE SURFACE
While ascending to shallower depths, the segments that have filled up the NIBG will begin
to recede, offering a graphic representation of your multilevel diving capability.
By backing off on the NIBG (maintaining fewer segments), you can
establish a personal level of conservatism and margin of protection.
If you entered Decompression, you must not complete your ascent until the NIBG is inside
the No Decompression Zone. You should make every effort to complete all of your ascents
with the NIBG inside of the No Decompression Zone.
While you cannot provide a guarantee against the occurrence of decompression sickness,
you may choose your personal zone of caution based upon your individual age, physique,
excessive weight, training, experience, etc. to reduce the statistical risk.
No Deco Safety Stop
If you have not entered Deco, a Safety Stop made between 10 and 20 FT (3 and 6 M) is
strongly recommended as a standard procedure before completing your ascent.
Depending on the model dive computer that you have, the Safety Stop feature could pro-
vide a fixed Stop Depth and Time, or you may be able to set them for a preferred depth
and Time.
