2. On any given dive, both divers in the buddy pair must follow the most conservative dive computer.
3. If the dive computer fails at any time during the dive, the dive must be terminated and appropriate surfacing procedures should be initiated immediately.
4. A diver should not dive for 24 hours before activating a dive computer to use it to control his diving.
5. Once the dive computer is in use, it must not be switched off until it indicates complete outgassing has occurred or 18 hours have elapsed, whichever comes first.
6. When using a dive computer, non emergency ascents are to be at a rate specified for the make and model of dive computer being used.
7. Ascent rates shall not exceed 40 fsw/min in the last 60 fsw.
8. Whenever practical, divers using a dive computer should make a stop between 10 and 30 feet for 5 minutes, especially for dives below 60 fsw.
9. Repetitive and multi-level diving procedures should start the dive, or series of dives, at the maximum planned depth, followed by subsequent dives of shallower exposures.
