3.13 Dive planning mode
The dive planning mode PLAN NoDeco can be used to plan a dive
that does not require decompression. You enter the depth of your
upcoming dive, and Suunto D4i calculates the maximum time you
can stay at that depth without requiring decompression stops.
The dive plan takes into account:
•
any calculated residual nitrogen
•
dive history from the past four days
To plan dives:
1.
Press [MODE] until you see
PLAN NODEC
.
2. The display briefly shows your remaining desaturation time
before continuing to the planning display.
3. Press [DOWN] or [UP] to scroll your upcoming dive depths. The
depth moves in 3 m (10 ft) increments from 9 m – 45 m (30 ft –
150 ft). The no-decompression time limit for the selected depth
is shown in the center of the display.
If you have dived at least once with Suunto D4i, the
SURFTIME +
field appears. You can adjust the surface time with [UP].

surface time.
