Course Details: DSAC Tec Diver course:  Tec 40 / 45 / 50
 
Course Name Tec 40 / 45 / 50

Overview
In 2000 DSAT (Diver Science and Technology) introduced the TecRec series for deep, open circuit tec diving.  The Tec Diver course consists of three sub courses:  Tec40, Tec45 and Tec50.  The number in each course corresponds with the maximum depth divers are qualified to dive in with each level.
 
Tec 40: This is the first step to entry level technical diving rating you to 40 metres including decompression and higher gas mixes.
 
Tec 45: The next step rating you to 45 metres
 
Tec 50: Qualifies you to dive to 50 metres with full decompression and up to 100% O2 useage.  Also allows you to progress onto trimix and extended range diving.

General Content
Tec40:  This course is for those interested in trying limited decompression diving as well as those wishing to progress further.  All decompression is based on desktop decompression programmes (pre dive planning) and dive computers (during the dive).
 
Tec45:  This is the next step for continuing Tec diver training, and you'll learn skills intended for Tec50 and beyond.  You'll learn to calcualte dive plans 'by hand', but the emphasis is on using multi gas dive computers coupled with decompression software.
 
Tec50:  This carries through the training started in Tec45 and emphasises dealing with the complexities of two-gas decompression diving.
