TDI - O'Dive Doppler Technician

$350.00 USD

TDI O'Dive Doppler Technician Course

This course provides the training required to allow candidates to competently conduct field readings utilizing the O’Dive Doppler system so as to better optimize personal decompression strategies. The objective of this course is to train candidates in the proper techniques, equipment requirements and problems involved in taking O’Dive Doppler readings and interpreting the information generated.

Course prerequisites

  1. Minimum age 18

  2. Minimum certification of SDI Advanced Adventure Diver , Advanced Diver, or equivalent

  3. Provide proof of 25 logged open water dives

What you can expect to learn:

  1. Principles of Doppler

    1. Christian Doppler

    2. Doppler concept

    3. Uses of Doppler

    4. Doppler used for diving research

  2. Overview of Decompression Safety Stops Compared to Required Stops

  3. Physiology/Physics

    1. Mechanics of bubble formation

    2. Advantages of hyperoxic mixes for decompression

    3. Nitrogen absorption and elimination

    4. Ascent / Descent rates

    5. Hypothermia

  4. Decompression Options a. Air

    b. Nitrox

    c. Oxygen

  5. Decompression Models

    1. Haldanian/Neohaldanian

    2. Workman/Buhlmann and Gradient Factors

    3. VPM

    4. RGBM

    5. DCIEM

    6. DCAP

    7. Deep Stops

  6. O'Dive Operation

    1. Setup

    2. Using the app

    3. Taking readings

    4. Other features

    5. Maintenance and storage

  7. O’Dive Approach

    1. Bubble Component (Bc) Calculated from the analysis of the acoustic signals of the vein based on the observed Grade from 0 to 4 (Spencer's scale)

    2. Severity Component (Sc) from severity index formula Hempelmann 𝑃√𝑡=Is improved by Azoth systems to consider decompression time and gases

    3. O’Dive IQ concept design QI=100-(Cs+Cb)

    4. The variable


      Analysing the Data

Some of the required skills you will have to demonstrate include:

  1. Candidates must successfully carry out minimum 2 individual O'Dive Doppler readings.

  2. Candidates must satisfactorily complete 2 individual O'Dive Doppler Analysis. This can be done on readings obtained from themselves or team members post dive or if no dives are carried out can be done on predefined readings included in the powerpoint.

  3. Satisfactorily complete the TDI O’Dive Doppler Decompression Technician written examination

  4. Demonstrate understanding of the O’Dive Doppler Sensor and O’Dive App

What’s in it for you?

Upon successful completion of this course, graduates may engage in O’Dive Doppler readings post dive, without direct supervision.
