What does the term run time mean? How does it differ from bottom time?
What is it you need to be prepared for in terms of decompression and available gas?
How long should bottom time be?
Key Points to Remember
Technical divers frequently use the term run time to characterize the elapsed time from initial descent to any given point during the dive.
Your dive plan needs to allow for the possibility you may exceed your planned bottom time or fall far short of it. You need to be prepared for either contingency in terms of decompression and available gas.
Bottom time should only be long enough to meet a realistic set of goals and objectives.
