100. Dive Modes

101. Dive Time Remaining (DTR) One of the most important pieces of information on Sherwood dive computers is the Dive Time Remaining (DTR) numerical display. The Wisdom2 constantly monitors: 1.No Decompression (NDL) status 2.Oxygen Accumulation 3.Breathing Gas Consumption Rate

102. Dive Time Remaining (DTR) The Dive Time Remaining display will indicate a)No Decompression (NDL)

103. Dive Time Remaining (DTR) The Dive Time Remaining display will indicate 1.No Decompression (NDL) 2.O2 Dive Time Remaining a)In the instance where oxygen accumulation becomes the limiting factor

104. Dive Time Remaining (DTR) The Dive Time Remaining display will indicate 1.No Decompression (NDL) 2.O2 Dive Time Remaining a)In the instance where oxygen accumulation becomes the limiting factor 3.Airtime Remaining a)When air consumption time is less than NDL b)Calculated using diver’s air consumption rate and current depth c)Tank Icon will appear flashing as a warning

105. No Deco Safety Stop Upon ascending to 20 feet on any No Decompression dive in which depth exceeded 30 feet a 3 beep alarm will sound and SAFE STOP screen appear. Countdown Timer begins at 3:00 min Counts down minutes and seconds Safety Stop is not Mandatory and no penalty occurs if you surface during countdown

106. No Deco Deep Stop Upon descending below 80 feet on any No Decompression dive a 3 beep alarm will sound and Deep Stop screen appears Countdown Timer begins at 2:00 min Counts down minutes and seconds Deep Stop is not mandatory and no penalty occurs if you surface during countdown
