General information

Watch our video tutorial to learn how to properly place your O’Dive sensor.
Caution: Pressure sensors are no longer used as of version 1.8.48 of the application (see Taking a measurement).

Watch our video to learn how to interpret your results and become familiar with the O’Dive personalized simulator.

Charging the sensor

When your sensor is properly placed on the charger:

  • the ON/OFF button is flashing in green
  • the charger lights up in green for 16s then off

When your sensor isn’t properly placed on the charger:

  • the ON/OFF button stays off or is flashing in red
  • the charger’s LED stays off or is flashing in green

Remove the sensor from the charging base and replace it properly so that:

  • the ON/OFF button is flashing in green
  • the charger lights up in green for 16s then off

Managing accounts

Caution: ensure that you have granted access to the phone’s camera to the O’Dive app.

Caution: ensure that the sensor is turned on as well as the device’s (phone or tablet) Wi-Fi connection.

Taking measurements and parameters input

Caution: ensure that wireless tethering is turned off on your smartphone.

  • In order to properly position the sensor, we recommend you to watch the tutorial and to use the mirror.
  • Remember to follow these instructions during the measurement:
    Breathe deeply || Keep your arm relaxed along your body and do not move || Do not talk.
  • The pre-measurement spectrogram allows the correct positioning of the sensor to be checked by means of direct visual feedback of the acoustic signal.
    The visual objective is to obtain a yellow-red signal with the greatest possible height and length (see examples below). A periodic signal indicates correct positioning.
    It is important to stay still for a few seconds to check the quality of the signal.
  • Please retake the measurement in case of uncertain positioning.

 

Example of a signal with a correct positioning:

Example of a insufficient-quality signal:

Caution: ensure that you have filled all the fields and don’t forget to validate.

Caution: it is mandatory to importer the profiles for multi-level dives. Manual input is only valid for square profiles.

  • There are several ways to import your dive settings into the O’Dive application:
    1. Shearwater : you can connect your Shearwater dive computer directly to the O’Dive application via Bluetooth
    2. Suunto : you can log in to your Suunto Cloud account to synchronize recorded dives
    3. Subsurface : you can connect to your Subsurface Cloud account to synchronize recorded dives. Please see the sections below to record your dives under Subsurface.
  • Make sure to enter all the fields (some are not imported) and don’t forget to validate.

Subsurface

Caution: you must beforehand connect the smartphone to the dive computer via Bluetooth in your smartphone settings​.

Results and simulator

Caution: ensure beforehand the good quality of your internet connection.

  • Synchronized dives can not be modified (you can not add other measurements).
  • To obtain your results, you must synchronize again after receiving the email.
  • Click on the bargraph to access the detailed result.
  • Two factors can lower the Quality Index:
    Severity component (1st box): it depends on the diving parameters, gas mix and ascent profile
    Bubbles component (2nd box): it depends on the quantity of micro-bubbles detected in the diver’s venous system. (max. value: 40).

O’Dive One simulator offers the possibility of modifying the following parameters and see their impact on your decompression’s quality:
– decompression stop’s duration
– decompression gas
– bottom gas.

O’Dive Tek simulator offers the possibility of modifying the following parameters and see their impact on your decompression’s quality::
– decompression stop’s duration
– diluent gas
– PpO2
– Gradient Factors (GF Low is limited depending on depth and gas used).

You can find below the recommendations and advices based on the personalized decompression analyses:

  • Use oxygen enriched mixtures (Nitrox) during decompression or at the bottom;
  • Use helium enriched ternary mixtures (Trimix) when diving deeper than 50m or even 40m if possible;
  • Respect legal diving limitations: 50m with air, 120m with Trimix and 1.6 bar PpO2 max;
  • Avoid setting a too low value for GF Low, especially if the maximum depth and bottom duration are low values;
  • Program your decompression profile with O’Dive to keep your Quality Index between 75 and 100 for your dives.
