HALCYON SYMBIOS CCR TUNE-UP · PUERTO AVENTURAS, MEXICO

Refresh the skills that matter.

An independent one-day tune-up for qualified Symbios CCR divers who want to revisit critical knowledge, practise important procedures and sharpen the way they respond when something is not right.

A tune-up, not another course

This is a practical opportunity to revisit the parts of Symbios diving that benefit from discussion, repetition and feedback.

The session is for divers who already hold at least an entry-level certification on the Symbios CCR. It is not intended to repeat your original course or replace appropriate continuing training.

The exact emphasis can be adapted to the participants. We start by identifying your experience, recent diving and the areas you want to revisit, then use the dry and in-water sessions to work through the most useful material.

What we cover

Half of the day is spent on guided dry discussion and half in the water.

Dry session

  • Setpoints and PO₂ control
  • Oxygen-feed isolation and its consequences
  • Sensor interpretation, including GreenFlash sensors
  • Recognising and responding to possible CO₂ problems
  • Bailout planning and gas requirements
  • Using the digital checklist without becoming dependent on it
  • Fault-finding and the limits of owner maintenance
  • Sensible spares and preparation for travel

In-water session

  • A focused review of critical core skills
  • Selected basic failures and simple scenarios
  • Oxygen freeflow into the unit
  • Diluent freeflow into the unit
  • Oxygen-feed isolation
  • Bailout ascent practice
  • Rescue practice with feedback and repetition

Who can attend?

To attend, you must hold at least an entry-level certification on the Symbios CCR, regardless of training agency, and bring your own dive-ready unit and normal personal diving equipment.

Sessions are limited to three divers so that each participant receives useful individual feedback.

Experience with Symbios

I have been involved with the Symbios CCR since before the unit was first made public. I was the first instructor to teach it and have contributed to the development, writing and review of training materials for the unit. I am also an approved Halcyon Symbios factory trainer and a GUE Instructor Evaluator on Symbios.

That combination of technical knowledge and teaching experience allows us to go beyond simply rehearsing drills. The aim is to improve how you understand the unit, interpret what it is telling you and respond to problems in a deliberate, structured way.

Would a tune-up be useful?

Tell me about your Symbios certification, recent diving and the areas you would like to revisit. I can confirm whether the session is appropriate and discuss possible dates.
