TDI Deco Procedures / Helitrox
Go Beyond Your Limits — Master the Art of Decompression Diving
Do you ever wish your dives could last longer? The TDI Decompression Procedures / Helitrox Courses at Blue Ribbon Dive Resort in Anilao is your gateway to extended-range diving — designed for experienced divers who want to move beyond no-decompression limits and master the planning and execution of staged decompression dives.
Here in the center of the center of marine biodiversity, you’ll gain real-world experience exploring deeper reefs and walls while developing the precision, discipline, and situational awareness that define technical diving.
This course can be taken on twin tanks or sidemount, and is often paired with TDI Advanced Nitrox to form the foundation of your future technical diving journey.
Prefer a smoother narcosis profile and clearer thinking at depth? You can also choose the TDI Helitrox Course — the same training with the added benefits of helium in your breathing mix for enhanced safety and comfort at depth.
With a maximum training depth of 45 metres, this is where your true extended-range adventure begins — unlocking a whole new level of underwater exploration.

What Skills Will You Learn?
Your TDI Decompression Procedures / Helitrox training at Blue Ribbon combines theory, workshops, and open-water sessions to develop precision, confidence, and control underwater. You’ll learn how to:
Plan and execute staged decompression dives to a maximum of 45 metres
Calculate gas requirements, ascent profiles, and oxygen exposure limits
Configure, analyze, and label decompression cylinders and gases (air, nitrox, or oxygen)
Perform S.T.A.R.T. pre-dive checks, gas matching, and team communication
Maintain neutral buoyancy and perfect trim during staged stops and gas switches
Use DSMBs for controlled ascent and drifting decompression
Handle emergency scenarios such as gas loss, missed stops, or equipment failure
Training can be done in twinset or sidemount configuration, using the same equipment setups employed in advanced technical diving. You’ll gain the knowledge and in-water skill to manage both depth and time — with precision and confidence
What Are Scuba Classes Like?
Get Smart with eLearning
Start with TDI Decompression Procedures eLearning, where you’ll explore decompression theory, gas laws, physiology, and dive planning models like Bühlmann and RGBM. You’ll understand how staged decompression works and how to safely apply it in real dives.
Get Practical with Workshops and Drills
Once you arrive at Blue Ribbon, your instructor will guide you through equipment setup, gas analysis, and emergency procedures. You’ll run land drills covering ascent planning, lift bag deployment, and problem-solving techniques before moving to the water.
Go Diving in Open Water
You’ll complete four decompression dives, at least two deeper than 30 metres, right here in Anilao’s clear blue waters. Under close supervision, you’ll apply everything you’ve learned — from gas switching to DSMB ascents — refining your skills with each dive.
At Blue Ribbon, we keep classes small to ensure personalized instruction, giving every diver the focus and feedback needed to excel.
