In the early 2000s, I became interested in technical diving. Living in Sydney, we are fortunate to have a variety of wrecks in the 45m to 80m range.
This offered me the opportunity to push my diving further and further my career as a technical diving instructor.

I have always approached this type of diving with the mindset of using the best possible equipment on the market, built by people at the forefront of technical and cave diving. This is what led me to Halcyon Dive Systems and my first piece of Halcyon equipment in 2001: an Explorer 40 wing and backplate. I was fascinated by the dives where the equipment was being used โ€” extreme deep ocean diving and cave exploration. I knew I had found my place.

Since then, I have been lucky enough to have a successful career as a technical diving instructor and to be part of many exploration projects around the world, from the first cave diving exploration in China to numerous deep wreck diving projects across the globe โ€” from the freezing temperatures of the Baltic Sea to the tropical and temperate waters of the South Pacific.
While the equipment has evolved over the years, one thing within Halcyon has not: the drive for innovation and performance-driven products.

One standout in the evolution of Halcyon equipment is the Symbios CCR. In 2009, I learned to dive the Halcyon RB80, my first rebreather. It was a time when eCCRs were evolving, and the non-electronic RB80 was very appealing to me.

Fast forward to today and the newly released Halcyon Symbios eCCR. Its lightweight and compact size is fantastic for travel, and its simplistic design is packed with technology, including the worldโ€™s first wireless communication system between the rebreather, HUD, and handset.

On this 30th anniversary of Halcyon, the release of the Symbios suite of products highlights that the brand remains true to its core values and marks the beginning of the next 30 years. Happy Birthday Halcyon!

Simulate an open circuit or rebreather dive from your app while on the surface, adjusting all variables and seeing how the computer responds. View and cancel warnings, scroll through all screen layouts, and gain insight into deeper operations before you enter the water. You can control depth, ascent/descent speed, gas pressures, individual PO2 readings and more.

Enhanced CCR Performance

Several improvements have been made to increase system performance and reliability:
โ€ข The Dynamic Setpoint can now be configured up to 1.3 bar
โ€ข Greenflash optode sensor readout and stability have been further improved
โ€ข The exact reason for a sensor calibration failure is now displayed, identifying both the affected sensor and the cause of the failure
โ€ข Intelligent Ascent Setpoint Control

A new intelligent ascent algorithm automatically adjusts the selected setpoint when the requested value cannot be achieved at the current depth. For example, if a diver ascends while still using a high setpoint, the system will automatically provide the best achievable setpoint for that depth without requiring userintervention.

Unlike systems that continuously inject oxygen or switch to a lower setpoint only at predefined depths, Symbios dynamically adapts throughout the ascent to provide optimal performance.

A fully integrated ๐๐ข๐ฏ๐ž ๐ฉ๐ฅ๐š๐ง๐ง๐ž๐ซ has been added to the Handset. The planner calculates decompression obligations in both Open Circuit and Closed Circuit modes and estimates gas consumption during 0pen Circuit dives.

Additional safety improvements include:

โ€ข A new ascent rate warning system alerts divers when ascent speed exceeds 10 m/min.
โ€ข The Handset will additionally vibrate when ascent speed exceeds 20 m/min
โ€ข This warning function can be enabled or disabled by the user
โ€ข Buttons can now be configured to deactivate automatically when depth exceeds 100 m.

Please note that firmware updates for Symbios CCR Heads running older firmware are performed via a USB connection to a desktop or laptop computer whereas Symbios Handset and HUD updates can be completed wirelessly through the Halcyon App.
