New Jersey Scuba Diving

You may specify Ascent and Descent Rates for both deep and shallow segments of a dive, along with a "split" depth in feet. Rates may be set between 10 and 100 feet per minute; no negative numbers. Un-checking the boxes disables Ascent / Descent modeling. This is not a good idea but is sometimes useful for comparing with old square-profile schedules and softwares. By default, only the first big descent is shown in the profile, the rest are suppressed from the display. If you want to see everything, check 'show'.
