Questions and Answers for Mares Mission Puck Air / Nitrox 3 Gauge Computer Console:
DOES THIS CONSOLE COME WITH A SAFETY STOP MECHANISM @ 15 FEET WERE ITS HAS A COUNTDOWN FEATURE?
Bill (Certified Scuba Instructor at Scuba.com)
If the maximum depth of a dive exceeds 30 feet (10 meters), a “Safety Stop” is activated for the ascent. PUCK suggests that divers take a 3-minute safety stop between 2.5 and 6 min depth (8 - 19 ft), and will display the word “SAFE”. A timer indicates the time needed to complete the stop.
