ReACT Pro
GLOSSARY
Air Dive - A dive conducted using AIR (approximately 21% oxygen & 79% nitrogen) as the breathing gas.
Algorithm - A step-by-step mathematical formula designed to accomplish a particular result (i.e. Dive Time Remaining in the ReACT Pro).
Altitude Dive - A dive made at an elevation above sea level (> 3,001 feet) where no decompression limits are adjusted.
Ascent Rate - The speed that a diver ascends toward the surface.
Ascent Rate Indicator - A graphic representation of vertical ascent rate (speed) displayed alongside a color coded indicator.
Boot - A protective rubber covering that surrounds an instrument module.
Bottom Time - The total time spent underwater during a dive between 5 FT (1.5 M) on initial descent to 2 FT (0.6 M) on final ascent.
BT - Abbreviation for Bottom Time (Elapsed Dive Time).
Caution Zone - The section of a bar graph that gives visual warning of a diver’s proximity to projected limits.
Ceiling - See decompression ceiling.
Clean Dive - A dive preceded by 24 hours of no diving activity.
Competitive Dive - A dive conducted for profit or prize.
Compartment - A term applied to the hypothetical modeling of nitrogen absorption in the tissues (more accurate than the term “tissue” because dive
computer models have no direct relation to human tissues).
CNS - Abbreviation for the Central Nervous System of the body.
DCS - Abbreviation for decompression sickness (i.e., the bends).
DECO - Abbreviation for Decompression.
Decompression Ceiling - The shallowest depth a diver may reach upon ascent without risking DCS.
Decompression Stop - The depth(s) at which a diver must pause during ascent to allow absorbed nitrogen to escape naturally from the tissues.
Depth Sensor - An electromechanical device that converts water pressure into an electrical signal, that is converted to a visual depth display.
Diagnostic Mode - The first display seen on Genesis Scuba dive computers after initial activation during which time a self check for internal faults
and battery voltage is performed.
Display - A visual readout of information.
Dive Time Remaining - A display of time allowed before a diver must surface based on decompression status or oxygen saturation.
FO2 - The fraction (percent / 100) of oxygen (O2) in the breathing gas mixture.
Hydroglow - A Genesis Scuba term for an instrument backlight feature.
LCD - Abbreviation for liquid crystal display, an easily viewed low voltage display usually found on dive computers
Log Mode - A computer display of previous dive information.
