Nemo Diving Center’s technical diving course pathway has six distinct stages, and it is genuinely easy to misjudge where you actually belong in it. This is a direct, honest comparison of what each level requires, so you can place yourself accurately before booking anything.
Start With What You Already Hold
The single biggest factor in where you start is your existing certification, not your ambition. Every stage in this pathway has a hard prerequisite, and PADI does not allow skipping levels regardless of how experienced you feel.
If You Hold PADI Advanced Open Water Diver and Nothing Further Technical
Start with Discover Tec Diving. At AED 400 for a single four-hour session, it is a no-certification experience that puts you in full technical kit, backmount or sidemount, in a shallow, controlled pool environment. It requires no more than what you already have, plus a medical statement, and it is genuinely the lowest-risk way to confirm technical diving is worth pursuing further.
If You Meet Tec 40’s Prerequisites but Your Trim and Buoyancy Feel Shaky
Start with Tec Basics rather than going straight to Tec 40. From AED 1,000 over two days, it is not a certification, but it directly targets the skills, trim, buoyancy, multi-cylinder handling, that Tec 40 assumes you already have. Divers who skip this step and go straight into Tec 40 without solid technical-configuration comfort tend to struggle with equipment handling more than theory.
If You Hold PADI Enriched Air Diver, PADI Deep Diver (or 10 dives to 30m), and 30+ Logged Dives
Start with Tec 40 directly. From AED 3,500, this is the real entry point into certified technical diving, taking you to 40 meters with limited decompression diving. If your buoyancy and trim are already solid, either from experience or from completing Tec Basics, this is where your actual technical certification begins.
If You Already Hold Tec 40, Plus Rescue Diver and 50+ Logged Dives Including 10 Past 30m
Move to Tec 45. Priced at AED 2,800 (confirm current rate before booking, since this figure currently sits below both Tec 40 and Tec 50), this extends your depth to 45 meters with more demanding, longer decompression obligations using one deco mix.
If You Already Hold Tec 45, Plus Rescue Diver and 100+ Logged Dives or 75+ Hours Underwater
Move to Tec 50. At AED 3,500, this is the top of the core Tec Deep pathway, taking you to 50 meters with multi-stage decompression across multiple gases. The jump from Tec 45’s 50-dive minimum to this level’s 100-dive minimum reflects how much more experience this stage genuinely assumes.
If You Already Hold Tec 50, Plus 100+ Logged Technical Dives With Real Decompression Experience
Move to Tec Trimix 65, starting at AED 5,000 with additional costs applying separately. This introduces helium into your gas mix for the first time, extending your range to 65 meters over roughly 4 days, with Full Trimix beyond that reaching 75 to 90 meters for divers who complete Trimix 65 and continue building experience.

Frequently Asked Questions
Can I skip a level if I feel ready for it?
No. PADI’s technical certifications are sequential, and Nemo enforces the prerequisite chain for each one. Feeling ready is not the same as meeting the logged-dive and certification requirements.
What if I am not sure which prerequisites I actually meet?
Contact Nemo Diving Center directly with your current certifications and logged dive count. They can confirm exactly where you fit before you book anything.
Is Discover Tec Diving worth doing even if I already qualify for Tec 40?
It can be, if you have never handled full technical kit before and want a low-stakes way to confirm the equipment and skills feel right before committing to a paid certification course.
Why is Tec 45 priced lower than Tec 40 and Tec 50?
That is a genuine inconsistency on the current pricing as listed, worth confirming directly with Nemo before booking rather than assuming it reflects the course’s real value or scope.
How long does the full pathway realistically take?
Each stage is a separate booking with its own multi-day structure, and each certification must be completed before the next begins, so realistically the full pathway from Tec 40 to Trimix spans months, not weeks, depending on how quickly you build the required logged dives between stages.
