Technical diving courses in India
You do not have to leave India to learn technical diving. I teach the full path here, from sidemount and Tec 40 through trimix to 100 m and the KISS Sidewinder rebreather, in Pondicherry and Lakshadweep, with cavern and sidemount training in the caves of Meghalaya.

Where I teach in India
Pondicherry
Tamil Nadu coast
Every course I teach runs here, from fundamentals through trimix and CCR. Most courses start here.
With: Chakra Divers
Lakshadweep
Agatti and Kavaratti
Every course runs here too, on the deep walls of the Lakshadweep atolls. I made the deepest verified civilian dive in India here: 103 m on open-circuit trimix, in March 2026.
With: Ammathi Scuba, Lak Scuba, LakSea Adventures
Meghalaya
East Jaintia Hills
Fundamentals, sidemount and cavern courses, run alongside the cave exploration expeditions in the East Jaintia Hills.
Courses in India
Tec 40 / Intro to Tech
3 days
The first step into technical diving: limited decompression stops, real gas planning, and the discipline shift that separates technical divers from recreational ones. PADI Tec 40 or TDI Intro to Tech.
Tec 45 / Advanced Nitrox & Decompression Procedures
4 to 5 days
Genuine staged decompression to 45m: multiple deco gases, failure management mid-dive, and the discipline that comes from knowing you can't abort to the surface. PADI Tec 45 or TDI Advanced Nitrox & Decompression Procedures.
Tec 50 / Extended Range
4 to 5 days
Air and nitrox to 55m, the ceiling of air-range technical diving, where narcosis becomes a management problem rather than a background condition, and where the argument for trimix moves from theory to lived experience.
Trimix 60 to 75m
4 to 5 days
Normoxic and hypoxic trimix for the 60 to 75m range: helium gas planning, the narcosis reversal you have to experience to understand, multi-stage logistics, and the gas supply chain that makes trimix training actually work in this region.
Advanced Trimix / Road to 100m
5 days
Hypoxic trimix to 100m: multi-gas decompression management, expedition-level planning, and failure response at the depth where consequences compound fastest. PADI Tec 100 or TDI Advanced Trimix.
Sidewinder CCR MOD1
6 to 7 days
CCR MOD1 on the KISS Sidewinder sidemount rebreather, for divers who understand that rebreathers kill at ten times the rate of open-circuit and want the training discipline that makes the difference. Expedition experience across caves, ocean, and deep walls.
Sidemount Diver
4 days
4 days, 3 long dives, 1 pool session: proper sidemount configuration, buoyancy and trim specific to sidemount, and the body mechanics that make it feel like it was designed for you.
Cavern Diver
2 to 3 days
Overhead environment training within the natural light zone: the psychological and technical shift that happens when you can no longer ascend directly. Anti-silt propulsion, gas discipline, line handling, and stress management for partially-overhead spaces.
Advanced Wreck Diver
2 to 3 days
Penetration wreck diving to TDI standards: structure assessment, line discipline, zero-visibility exit, and the decision-making framework that determines when not to go in. Honest about what actually kills wreck divers.
Common questions
Can I learn technical diving in India?
Yes. Tec 40, 45 and 50, trimix to 100 m, sidemount, cavern and KISS Sidewinder CCR courses all run in India, in Pondicherry and Lakshadweep, with cavern and sidemount courses in Meghalaya.
Can I do a CCR rebreather course in India?
Yes. The KISS Sidewinder CCR MOD1 course runs in Pondicherry and Lakshadweep. Rebreather training is the core of what I teach, and you can do it without leaving India.
Where can I do a trimix course in India?
Trimix courses to 60, 75 and 100 m run in Pondicherry and Lakshadweep. Helium is arranged with the dive centre, and the gas supply is planned before the course starts.
Is there cave diving in India?
Yes, in Meghalaya. Cavern and sidemount training run there alongside the cave expeditions in the East Jaintia Hills.
Are there fixed course dates?
No. I do not run fixed training calendars. Dates are set around your travel and your current certification level. The schedule page lists the courses already planned.
