OPERATIONAL PERFORMANCE
Function:
Accuracy:
• Depth
±1% of full scale
• Timers
1 second per day
Dive Counter:
• Norm/Gauge displays Dives #1 to 24.
• Resets to Dive #1, upon diving (after 24 hours with no dives).
Dive Log Mode:
• Stores 24 most recent DIVE/GAUGE dives in memory for viewing
• After 24 dives, adds 25th dive in memory and deletes the oldest dive
Altitude:
• Operational from sea level to 14,000 feet (4,270 meters) elevation.
• Measures ambient pressure every 30 minutes in Watch mode, when Dive Computer mode is accessed, and every 15 minutes while in DC Surface
modes.
• Does not measure ambient pressure when wet.
• Compensates for Altitudes above sea level beginning at 3,001 feet (916 meters) elevation and every 1,000 feet (305 meters) higher.
