Tec Trimix Diver

The Tec Trimix Diver course is the top of ClanDestino Sub's technical diving program, taught by Davide Franceschetti who holds a PADI Trimix Instructor qualification — a rating that is uncommon at a club-level operation anywhere, and particularly so in the inland north of Italy. The course covers planning and executing dives using trimix gas blends, managing multiple cylinders and gas switches, handling extended decompression obligations, and using the redundant equipment configurations required at these depths. Students reaching this level will already have completed the Tec 40, Tec 45, and Tec 50 stages of the PADI TecRec sequence.

Prerequisites for the TecRec program generally include being 18 or older, having 100 logged dives, holding PADI Enriched Air Diver and Deep Diver certifications or documented equivalents, and providing medical clearance for technical diving. The progression through Tec 40, Tec 45, and Tec 50 builds the decompression planning, gas management, and equipment redundancy skills that Tec Trimix then extends to deeper exposures and helium-based mixtures. Each level is designed to be completed separately with time between, or run consecutively — the structure allows training to fit around the student's schedule and logistical constraints.

Technical diving trips from this club focus on sites accessible from Lago di Garda and sea locations the group regularly visits. Deep wrecks and walls that fall outside the recreational depth ceiling are the main draw for divers who progress through the TecRec sequence to this level. Planning those dives requires the full toolkit that the Tec Trimix course develops: precise gas blending calculations, multi-stop decompression schedules, and the equipment discipline to manage equipment failures at depth where surfacing immediately is not an option.

For divers already in the TecRec sequence with ClanDestino Sub, Davide's Trimix Instructor qualification means there's no need to seek out another instructor or travel to a specialist technical centre to complete the certification. That continuity — same instructor, same club, same diving community — is one of the practical advantages of a club that has built its technical program from Tec 40 through to Trimix rather than stopping partway up the stack.
