ALTITUDE DIVING PROCEDURE

2. Plan the dive based on the altitude and the theoretical depth in conjunction
with the actual depth of the dive.
3. Dive the actual depth using the correction factor when needed.
4. Ascend at the proper ascent rate for the altitude being dived.
5. Perform a safety stop at the appropriate depth for the altitude being
dived.
ALTITUDE DIVING RULES
