Personal and altitude adjustments

There are several factors that can affect your susceptibility to DCS. Such factors vary between divers and from one day to another.

The personal factors which tend to increase the possibility of DCS include:

  • exposure to cold water - less than 20°C (68 °F)
  • below average physical fitness level
  • fatigue
  • dehydration
  • stress
  • obesity
  • patent foramen ovale (PFO)
  • exercise before or after dive

The three-step personal setting can be used to adjust the algorithm to fit your DCS susceptibility.

In addition to the personal setting, Suunto Zoop Novo can be adjusted for diving at different altitudes. This adjusts the decompression calculation according to the selected altitude adjustment.

Altitude adjustmentExplanation
00 – 300 m (0 – 980 ft) (default)
1300 – 1500 m (980 – 4900 ft)
21500 – 3000 m (4900 – 9800 ft)

To change the personal and altitude adjustment settings:

  1. While in a dive mode, keep DOWN pressed.
  2. Press SELECT to enter Personal Altitude settings.
  3. Press UP to change the Personal adjustment and confirm with SELECT.

Traveling to a higher altitude can temporarily cause changes to the equilibrium of dissolved nitrogen in the body. It is recommended that you acclimatize to the new altitude by waiting at least three (3) hours before diving.
