These are some of the most intensive, yet exhilarating, courses you'll find.

Discover Tec This short session allows divers to give technical diving a try. It does not result in a certification, but lets a diver experience wearing the extra gear involved in technical diving and understand the rationale behind it. Tec 40 The entry point into the technical range, Tec 40 provides a transition from recreational to technical diving. Although the use of full tech gear (doubles and wings) is preferred, it does allow modified use of recreational gear in some situations, provided the diver has two separate regulators, with one of the first stages fitted with a long hose. Double and single rigs(For example, a main cylinder and pony cylinder combination). The intended working limit for a diver at this level is 40 metres/130 feet with up to 10 minutes of non-accelerated decompression. They may use any EANx mix with up to 50% oxygen content or air. To enrol on the course, a diver must be the equivalent of a PADI Advanced Open Water diver, with an EANx Diver rating and have deep recreational diving experience. Tec 45 The diver must use full ‘standardised’ tech rig, including wings and doubles plus an additional deco cylinder (note that side mounted cylinders are an acceptable alternative to back mounted doubles throughout the TecRec range). The course allows the diver to go to 45 metres/145 feet and make accelerated decompression dives using any mix of EANx or pure oxygen. A diver must have the equivalent of a Tec 40 rating to enrol on this course. Tec 50 This course represents a high level of competency for a technical diver. Although the option exists to make the last dive of the course using trimix, it is intended as an air/nitrox rating and by the end the diver can dive to a maximum of 50 metres/165 feet and make extended, accelerated decompression dives.
