INSIGHT
WARNINGS:
Using the INSIGHT, just as using the U.S. Navy (or other) No Decompression
Tables, is no guarantee of avoiding decompression sickness (i.e., the bends).
Sherwood Scuba advocates responsible diving practices. Decompression
diving is inherently hazardous and greatly increases your risk of
decompression sickness, even when performed according to the computer's
calculations.
In the event that you must make an emergency decompression dive, you must
not make another dive for at least 24 hours.
OXYGEN EXPOSURE LIMITS (OTLS)
Predicted exposure limits and oxygen calculations of the INSIGHT are based on maximum exposure
durations published by the National Oceanic and Atmospheric Administration (NOAA) in the October
1991 NOAA Diving Manual (see Fig. 85).
Both central nervous system (CNS) oxygen toxicity and pulmonary oxygen toxicity were taken into
consideration when the limits were published by NOAA.
Although CNS oxygen toxicity is considered the primary constraint for higher levels of PO2, there are
circumstances in which pulmonary oxygen toxicity can limit exposures.
