Oceansports Technical Diving (Barbados) LTD conducts DSAT Tec Rec Deep & Trimix courses in Barbados. Tec Deep 40, 45, 50, Tec Trimix 65 & Tec Trimix training & certification are all being offered.
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.
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. (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.
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.
Tec Trimix 65
This course opens up the advantages of trimix to the diver, and divers are qualified to make multi-stop decompression dives that employ EANx and oxygen for accelerated decompression, using any trimix with an oxygen content of 18% or more. They can dive to a maximum depth of 65 metres/210 feet.
This course lets the diver go deeper, opening up the option of using travel gases and trimix with less than 18% oxygen content. Dives made during the course can be as deep as 90 metres/300 feet. Once qualified, the diver can start to explore deeper; for this reason there is no numbered suffix after the course title as in the rest of the range — there are no limits placed on how deep the diver can go after training, providing they build their experience gradually.
