Tec 40
Class cost include shore dives. Boat dives are optional.
Includes e-learning materials, certification and custom scheduling.
PADI Tec 40 is the entry-level certification in PADI's technical diving track — the bridge between no-stop recreational diving and true decompression diving.
Prerequisites: PADI Advanced Open Water Diver, PADI Enriched Air (Nitrox) Diver, and either PADI Deep Diver certification or proof of 10 logged dives to 100ft/30m or deeper (Rescue Diver is recommended but not required). You'll also need a minimum of 30 logged dives, to be at least 18 years old, and a Diver Medical Form signed by a physician within the past 12 months. Equivalent certifications from other agencies are generally accepted.
Course structure: 7 knowledge development sections, 4 practical application (confined water) sessions, and 4 open water training dives — typically completed over about 3–4 days.
What it certifies you to do: conduct limited decompression dives to 130ft/40m, using decompression gas with up to 50% oxygen.
Core skills: minimum-gas and reserve calculations, precise buoyancy and trim while carrying a stage bottle, gas-sharing and lost-gas contingency procedures, valve shutdown/isolation drills, and basic decompression dive planning.
What it's for: it's the required foundation before Tec 45 and Tec 50, and more broadly the on-ramp to wrecks, deeper reef diving, cave, and CCR — even for divers who never plan to go beyond this level, the precision it demands tends to make them noticeably better divers across the board.
