The Tec 40 course introduces divers to limited decompression diving within accepted recreational depth limits. The equipment requirements are only a bit beyond those of the standard recreational kit and among other things include an additional deco cylinder. Candidates interested in continuing their tec education later can do the course in a full tec rig.

A Tec 40 diver is qualified to use decompression software and dive computers to plan and make decompression dives with not more than 10 minutes of total decompression and not deeper than 40 meters and use a single cylinder of decompression gas. The breathing gas (same for bottom and deco) may include up to 50 percent oxygen.
