Between trying a technical kit for the first time and earning your first real technical certification sits a course most divers underestimate: Tec Basics Course in Dubai. It is not a certification in itself, but skipping it usually means struggling through the skills that Tec 40 assumes you already have.
What Tec Basics Actually Covers
Tec Basics is a preparatory course, priced from AED 1,000, run over two days across two sessions of about three hours each. Nemo Diving Center is upfront that this is not a PADI certification. It exists specifically to prepare you for Tec 40, not to replace it.
The course reaches a maximum depth of 24 meters, using air or enriched air up to EANx 40, with no-stop dives only, meaning simulated decompression practice rather than real staged decompression obligations. That distinction matters: Tec Basics lets you build the physical and mental habits of technical diving without yet carrying the real risk of a mandatory decompression stop.
What You Actually Do
The course opens with a classroom session covering technical diving philosophy, gear configuration, and gas theory, the thinking behind why technical divers rig their equipment the way they do. From there, you move into confined-water practice focused on equipment setup and S-drills, the standardized gas-sharing drills that every technical team relies on.
The course then moves to two shallow open-water dives, capped at 15 meters, where the emphasis is squarely on trim, buoyancy, and propulsion in a full tec setup, not depth or distance. You train in twin sets, sidemount harnesses, or stage cylinders depending on your intended configuration, so the gear you practice with is the same gear you will use in Tec 40.
Who Tec Basics Is For
You need PADI Advanced Open Water Diver with real deep and Nitrox diving experience behind you, Rescue Diver certification is recommended, and you should already be comfortable diving to 30 meters and handling multiple cylinders. This is not a course for divers still building basic comfort in the water. It assumes competence and focuses purely on the technical-specific skills layered on top of it.
Divers who benefit most are those who technically qualify for Tec 40 on paper but know their buoyancy, trim, or multi-cylinder handling is not yet where it needs to be. Better to find that out here than mid-course in Tec 40.
What’s Included and What Isn’t
Included: the classroom session, confined-water practice, two open-water dives, use of twin sets, sidemount harnesses, and stage cylinders during the course, and a course completion certificate.
Not included: PADI certification (this course does not award one), transportation, meals, accommodation, your personal dive kit or dive computer, dive insurance, nitrox tanks, and any advanced Tec courses beyond this one.
How Tec Basics Differs From Tec 40
The distinction matters more than it might seem. Tec 40 is a real PADI certification with genuine decompression exposure, requiring divers to already handle equipment configuration and buoyancy without conscious effort, since the course itself is focused on gas planning, decompression theory, and emergency procedures, not on refining basic trim. Tec Basics exists precisely because that expectation is a big jump from recreational diving. It isolates the physical and mental habits, weighting, propulsion, valve awareness, that Tec 40 assumes are already automatic, so that Tec 40 itself can focus on the genuinely new material: decompression obligations and gas switching under a real time and depth constraint.
Divers who arrive at Tec 40 without this preparation often find themselves managing two learning curves at once, the equipment and the decompression theory, which is exactly the situation Tec Basics is designed to prevent.
Where Tec Basics Leads
Successfully completing Tec Basics is the direct lead-in to Tec 40, Nemo’s first official technical certification. For the full pathway from here through Trimix, see the Technical Diving Courses in Dubai. If you have not yet tried technical equipment at all, Discover Tec Diving in Dubai is a lower-commitment starting point worth considering first.
Frequently Asked Questions
Is Tec Basics a real PADI certification?
No. Nemo states this explicitly: it is a preparatory course, not a certification, designed to get you ready for Tec 40.
Can I skip Tec Basics and go straight to Tec 40?
If you already meet Tec 40’s prerequisites and are genuinely comfortable with trim, buoyancy, and multi-cylinder handling, you can go directly to Tec 40. Tec Basics exists for divers who want a structured lead-in first.
What depth does Tec Basics reach?
A maximum of 24 meters overall, with the open-water dives capped at 15 meters, and no real decompression obligation since dives are no-stop only.
Do I need my own technical equipment?
Twin sets, sidemount harnesses, and stage cylinders are provided during the course. Personal gear like your mask, fins, wetsuit, and dive computer are not included.
Is Rescue Diver required for Tec Basics?
It is recommended rather than strictly required at this stage, but it becomes a hard prerequisite at Tec 45, so most divers complete it before or during this stage of the pathway regardless.
