TECHNICAL DIVING
WITH H2O
Fun with Deco Stops
Technical diving isn’t just about depth – it’s about advancing your knowledge and skills to safely push past the no-deco limits. Whether you’re extending your bottom time on a 30m dive at Thistlegorm or exploring the Blue Hole Arch, we’ll support you in achieving your goals with safety and proficiency at the forefront. Whatever your ambition, we’re here to help you succeed.
TECH DIVING IN DAHAB
Dahab offers incredible access to deep dive sites, making it a perfect location for technical training. Some sites feature stunning underwater landscapes that are off-limits to recreational divers, like the Blue Hole Arch starting at 54m or the Canyon, where you can exit at 52m and drop down to Neptune’s Cave at 75m. Beyond these iconic spots, we have other incredible sites such as Tiger House, Abu Helal/Tehla Canyons, Lighthouse Finger Reef, and Three Valleys, all offering unique and challenging dive experiences.
PREMIERE TECHNICAL FACILITIES
Are you a tech instructor looking to bring your group to dive in the warm waters of the Red Sea? At H2O, we offer premier technical facilities for visiting instructors, including blending panels for Helium and Oxygen mixes, a booster, Sofnolime, analyzers, dedicated sidemount cylinders, and a separate area to store your CCR, twinset, or sidemount kit. We’ve got everything you need to make your diving experience seamless and safe.
TECHNICAL
GUIDED DIVES
TWINSET * SIDEMOUNT * CCR
Technical guided dives in Dahab & Sharm.
Our equipment comes from top brands – Apeks, OMS, Halcyon, X-Deep – and is meticulously maintained to the highest standards.
We offer fully tailored technical diving packages for divers of all experience levels.
TRAINING COURSES
H2O is a TDI Professional Development Centre, providing a wide range of technical diving courses from Intro to Tech to Advanced Trimix Instructor, along with CCR training. We focus on tailoring our courses to match your learning style, allowing you to advance at your own pace while receiving expert instruction in a supportive environment.
INTRO TO TECH
Learn the fundamentals of technical diving; perfecting buoyancy, body positioning and finning techniques whilst learning the elements of diving in a twinset
TDI NITROX
DIVER COURSE
If you haven’t already got your Nitrox cert then we can start with this, learning how to use Nitrox mixtures up to EAN40 with the appropriate EAD calculations using Dalton’s Triangle
ADVANCED NITROX
This qualifies you to use Nitrox up to 100% Oxygen to a maximum depth of 40m. It can be used in place of a Deep Specialty course although having the Deep Spec is not equal to this course as we need to prepare using Oxygen for accelerated decompression
DECOMPRESSION PROCEDURES
/ HELITROX
Both courses qualify you to 45m with planned decompression stops. We have amazingly clear, warm waters here at depth but if you’re diving in different conditions Helitrox might be better to prevent narcosis
EXTENDED
RANGE / TRIMIX
55m is the deepest you can dive on air without pushing the Oxygen Toxicity limit (depending on conditions and narcosis factors) Trimix will qualify you to 60m with a minimum O2 of 18%
ADVANCED TRIMIX
COURSE
We have perfect sites in Dahab to be able to take you to serious depth in the calmest conditions. The pinnace of tech courses, this certifies you to 100m, which we’ll build towards to ensure you’re the most prepared you can be
(ADVANCED)
GAS BLENDER
Learn to competently and safely blend Nitrox and Trimix . After covering academic subjects including responsibilities of the gas blender, oxygen handling and gas production equipment and oxygen analyzing, you will demonstrate proficiency in blending nitrox.
PROFESSIONAL
LEVELS
At H2O, we have all TDI Courses available at Diver and also at Instructor levels.
CCR - REBREATHER COURSES
The future of diving, Closed Circuit Rebreathers (CCRs) recycle the gas you breathe, allowing for longer dive times. The absence of bubbles makes them ideal for photographers and nature lovers who want to enjoy silent, unobtrusive diving. For those going deeper, CCRs also significantly reduce helium costs, making them a smart choice for advanced divers.
AIR DILUENT CCR
Level one for recreational divers. Learn the fundamentals of your rebreather unit, learning everything you’ll need to execute 30m no deco diving
AIR DILUENT
DECO CCR / HELITROX CCR
Level one for tech divers, or 1.5 for those who’ve done their air diluent course. This certificate allows you to complete decompression dives to 40m (air dil) or 45m (helitrox).
MIXED GAS CCR
For those who want to go deeper! This course certifies you to 60m. Want to do the famous Arch at the Blue Hole? Then this is the level you’ll be aiming for!
ADVANCED MIX
GAS CCR
The course rebreathers were made for! During this course we’ll teach you to use hypoxic mixes in your CCR, slowly building up depth to a maximum of 100m
HUMAN FACTORS IN DIVING
This 2-day, dry course is designed to teach you all about Human Factors, providing you with the tools to make the right choices easier and the wrong ones harder. We’ll explore how to create a shared “mental model” with your dive team – essentially learning to think as one. Ever wished you could read someone’s mind? This is as close as you’ll get!
