The Tec 40 course bridges the gap between recreational diving and full technical deep decompression diving. Tec 40 introduces the use of dive planning software to undertake decompression dives with equipment that is more extensive than that used in mainstream recreational diving.

Divers will learn how to make limited decompression dives to 40m/130ft using a single stage cylinder of decompression gas. Double tanks (or side-mounted) are encouraged but not required on this course, although the full standardized technical diving rig will be discussed.
Decompression is limited to a maximum of 10 minutes with a single decompression gas up to 50% oxygen. Skills are introduced and developed to allow handling of reasonably foreseeable emergencies that may occur in this type of diving.
