O’Dive Sport

Unlimited user accounts
Free and unlimited dive analyses for the owner of the system (and a person of his or her choice)
For additional users: a total volume of 30 dive analyses are offered with the sensor, then dive analysis from 3€ (see our detailed offers)

O’Dive Sport helps you control your diving practice quality and improve your safety towards decompression sickness.

O’Dive Sport addresses to experimented divers – or accompanied divers – diving with air or nitrox in open circuit to 40 meters depth.

For the first time in the world, you can personalise your diving procedure considering at the same time the circulating microbubbles detected post-dive in your body and your dive profile.

The first connected technology to help you dive safer

An Android/iOS app


By choosing O’Dive, you can as many user accounts as you want. Your friends can also benefit from your sensor.

Air / nitrox dive

Tailored for recreational or sport diving, O’Dive Sport addresses air or nitrox scuba diving to 40m depth (open circuit only).


Each user is using his own confidential account. The data management policy at Azoth Systems is strictly following all the regulation regarding personal data confidentiality.


O’Dive sensor is easy to use and can be operated quickly in a fully autonomous way after surfacing.

O’Dive is committed to help improve scuba-diving safety

Decompression, a field to explore

For a 30-minute air dive at 30 metres and based on a standard level of conservatism (L0), divers can be offered 12 to 21 minutes of decompression stops depending on the model of their computer. This range extends from 8 to 50 minutes if all available settings are considered.

Given the diversity of decompression algorithms and the number of possible settings, divers have no tangible criteria to assess the level of suitability of their procedures to their own body.

A connected technology to better control the diving practice

A detailed outcome

O’Dive includes a robust, compact vascular microbubble sensor (ultrasonic Doppler technology) connected to a server with specialised analysis capabilities.

After the dive, divers place the sensor for twenty seconds under their left then right clavicle; they enter their dive parameters on the O’Dive application and synchronise their data.

About an hour later, they can visualise a personal QI index which value, between 0 and 100%, reflects the quality of their decompression.

When the quality index QI does not reach 100%, divers can access detailed information specifying the part of their result attributable to the severity of the dive itself (parameters) and the part attributable to the level of detected vascular microbubbles.

A fully customized simulation to improve one’s practice

An appropriate customization

Divers can also measure, by means of a simulation that is entirely theirs, the added value of several options on their practice:

  • Extend the duration of the last stop
  • Breathe a nitrox richer in oxygen at stops
  • Dive with nitrox, with the possibility of combining all these options

Dive after dive, a customised model that is specific to each diver is refined over time to reflect as accurately as possible the added value of each previous options on their safety.

State-of-the-art technology manufactured for the field

Developed over 10 years of research

O’Dive is the result of knowledge acquired over 10 years of research and development by Azoth Systems in collaboration with laboratories, diving doctors, physiologists and diving safety professionals.

About thirty experts from various backgrounds contributed to this knowledge. It is based on the analysis of hundreds of thousands of dives and the development of a technology shaped by years of user testing.

This momentum has given rise to 4 research theses, numerous scientific articles and several patents.
