  • Page 62: Safety Stops

    The reasons for performing a Safety Stop in- clude: reducing sub-clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. The Suunto D9tx displays two different types of Safety Stops: Recommended Safety Stop and Mandatory Safety Stop. 5.10.1. Recommended Safety Stops With every dive over 10 meters, there is a three-minute countdown for the Recommen- ded Safety Stop, to be taken in the 3–6 m/10–20 ft range.

  • Page 63: Mandatory Safety Stops

    (5) seconds, the microbubble build-up is predicted to be more than is allowed for in the decompression model. The Suunto RGBM calculation model responds to this by adding a Mandatory Safety Stop to the dive. The time of this Mandatory Safety Stop depends on the severity of the ascent rate excess.

  • Page 64: Deep Stops

    5.11. Deep stops The Suunto RGBM model calculates deep stops iteratively, placing the first stop about halfway between the maximum depth and the ceiling depth. After the first Deep stop is completed, another Deep stop will be prompted halfway to the ceiling, and so on until the ceiling depth is reached.
  • Page 65 If a deep stop is violated, it does not cause the dive computer to go into an error (Er) mode. However, a penalty time is added to the subsequent decompression. In the MIXED mode, the Deep stops are always activated. With Deep Stops ON, the Recommended Safety Stops will still NOTE be activated at the end of the dive.

  • Page 73: Decompression Dives

    6.1.7. Decompression dives When your NO DEC TIME becomes zero, your dive changes into a decompression dive. Therefore, you must perform one or more decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by an ASC TIME, and a CEILING notation will appear.
  • Page 74 YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DIS- WARNING PLAYED BY THE INSTRUMENT! The ascent time will increase if you: • remain at depth • ascend slower than 10 m/33 ft per minute or • make your decompression stop deeper than at the ceiling These factors will also increase the amount of air required to reach the surface.
  • Page 75 In such cases, it is more manageable to maintain an additional distance below the ceiling, to ensure that the waves do not lift you above the ceiling. Suunto recom- mends that decompression takes place deeper than 4 m/13 ft, even if the indicated ceiling is shallower.
