definitions given below apply specifically to the DataMax Sport.
Algorithm - A step-by-step mathematical formula designed to accomplish a
particular result (i.e. Dive Time Remaining in the DataMax Sport)
Altitude Dive - A dive made at an elevation above sea level where a differ-
ent set of no-decompression tables is used (4,000+ feet with the DataMax
Sport)
Ascent Rate - The speed that a diver ascends toward the surface
Boot - A protective rubber covering that surrounds an instrument console
Bottom Time - The total time spent underwater during a dive between 5
feet on initial descent to 3 feet on final ascent

gives a visual warning of a diver’s proximity to decompression
Ceiling - See decompression ceiling
Clean Dive - A dive preceded by 24 hours of no diving activity

absorption in the tissues (more accurate than the term “tissue” because dive
computer models have no direct relation to human tissues)
