  • Page 28: Compass Display

    4.4.1. Compass display The Suunto D9 displays the compass as a graphical representation of a compass rose. The rose displays the cardinal and half cardinal points, in addition to which, the current bearing is also displayed numerically.

  • Page 29: Locking A Bearing

    Locked bearings are stored in the memory for later analysis and are available the next time the compass is activated. The Suunto D9 also provides help for navigating square and triangular patterns, as well as navigating a return heading. This is made possible by following graphical symbols in the center of the compass display: Table 4.1.

  • Page 30: Compass Settings

    Symbol Explanation You are 120 (or 240) degrees from the locked bearing 4.4.3. Compass settings You can define the compass settings (declination and calibration) when in COMPASS mode: Declination You can compensate for the difference between true north and magnetic north by adjusting the compass declination.
  • Page 31 Calibration Because of changes in the surrounding magnetic field, the Suunto D9 electronic compass occasionally needs to be re-calibrated. During the calibration process, the compass adjusts itself to the surrounding magnetic field. As a basic rule, you should calibrate the compass whenever it doesn’t seem to operate properly, or after replacing the dive computer's battery.
  • Page 32 If the calibration fails several times in a row, it is possible that you are in an area with sources of magnetism, such as large metal objects, powerlines or electric appliances. Move to another location and try to calibrate the compass again. If the calibration continues to fail, contact an authorized Suunto service center.

    It is a significant advance on the classic Haldane models, which do not predict free gas. The advantage of Suunto RGBM is additional safety through its ability to adapt to a variety of situations and dive profiles.

  • Page 35: Dive Computer Limitations

    5.3. Dive computer limitations While the dive computer's calculations are based on current decompression research and technology, it is important to realize that the computer cannot monitor the actual physiological functions of an individual diver. All decompression schedules currently known to the authors, including the U.S. Navy Tables, are based on theoretical mathematical models, which are intended to serve as a guide to reduce the probability of decompression illness.

  • Page 36: Audible And Visual Alarms

    DCI. Therefore, FREEDIVING AFTER SCUBA DIVING IS NOT RECOMMENDED. You should avoid freediving, and not exceed 5 m/16 ft, for at least two hours after scuba diving. Suunto also recommends that you receive training in freediving WARNING techniques and physiology before conducting breathhold dives.

In these cases, re-enter DIVE mode to receive the battery power indication.

  • Page 57: Diving At Altitude

    5.10.4. Diving at altitude The dive computer can be adjusted both for diving at altitude and also to increase the conservatism of the mathematical nitrogen model. When programming the instrument for the correct altitude, you need to select the correct Altitude Adjustment settings according to Table 5.6, Altitude Adjustment settings. The dive computer will adjust its mathematical model according to the entered altitude setting, giving shorter no-decompression times at higher altitudes (see Table 9.1, No- decompression time limits for various depths (m) and Table 9.2, No-decompression...

  • Page 58: Personal Adjustments

    5.10.5. Personal adjustments There are personal factors that can affect your susceptibility to DCI, which you can predict in advance, and input into the decompression model. Such factors vary between divers and also for the same diver from one day to another. The three-step Personal Adjustment setting is available if a more conservative dive plan is desired and, for very experienced divers, a two step adjustment for RGBM effect on repetitive dives is available.
  • Page 59 Several risk factors or conditions exist The Suunto D9 also allows experienced divers who are willing to accept a greater level of risk to adjust the RGBM model. The default setting is 100%, which gives full RGBM effect. Suunto strongly advises you to use full RGBM effect. Statistically, very experienced divers have less incidents with DCI.

  • Page 60: Safety Stops

    The reasons for performing a Safety Stop include: reducing sub-clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. The Suunto D9 displays two different types of Safety Stops: Recommended Safety Stop and Mandatory Safety Stop. 5.11.1. Recommended Safety Stops With every dive over 10 meters, there is a three minute countdown for the Recommended Safety Stop, to be taken in the 6 - 3 m/10 ft - 20 ft range.

  • Page 61: Mandatory Safety Stops

    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 62 WHEN CEILING AND STOP ARE DISPLAYED, MAKE A ONE MINUTE MANDATORY SAFETY STOP IN THE DEPTH ZONE BETWEEN 6 M AND 3 M. You must not ascend shallower than 3 m/10 ft with the Mandatory Safety Stop warning on. If you ascend above the Mandatory Safety Stop ceiling, a downward pointing arrow will appear and a continuous beeping starts.

  • Page 63: Deep Stops

    5.12. Deep stops The Suunto D9 allows you to choose a Deep Stop algorithm instead of the traditional Recommended Safety Stop. Deep Stops are safety stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation and excitation.

    It is possible to record bookmarks in the profile memory during a dive. These bookmarks are displayed when scrolling the profile memory on the display. The bookmarks will also be shown as annotations in the downloadable Suunto Dive Manager PC software. The bookmark logs the depth, time, and water temperature, as well as compass heading (if the compass has been enabled)and tank pressure when available.

  • Page 67: Tank Pressure Data

    6.1.3. Tank pressure data When using the optional wireless pressure transmitter, the pressure of your scuba cylinder in bars (or psi) is shown digitally in the lower left corner of the alternative display. Whenever you start a dive, the remaining air time calculation begins. After 30 - 60 seconds (sometimes more, depending on your air consumption), the first estimation of remaining air time will be shown in the left center window of the display.

  • Page 68: Ascent Rate Indicator

    Filling your BC affects the air time calculation due to the temporary NOTE increase in air consumption. A change of temperature will affect the cylinder pressure and NOTE consequently the air time calculation. Low Air Pressure Warnings The dive computer will warn you with three audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar/725 psi.

    As a result, the allowed no-decompression-stop limits are considerably reduced. 9.3. Oxygen exposure The oxygen exposure calculations are based on currently accepted exposure time limit tables and principles. In addition to this, the dive computer uses several methods to conservatively estimate the oxygen exposure. For example: the displayed oxygen exposure calculations are raised to the next higher percentage •...
