The PADI TEC 40 course is the first step in the PADI Technical Diving system. It is intended as an entry level technical diving course that offers limited decompression diving, and with added conservatism built in to the gas planning and decompression. The course allows you to dive to a maximum depth of 40 metres, with a maximum of 10 minutes’ decompression, where a single decompression gas (50% max O2) can be used for decompression (but not to accelerate the decompression).
The course will introduce you to all of the equipment used for Technical Diving, the emergency skills and procedures required, and how to plan your limited decompression dive, along with the correct selection of breathing gases.
The benefit of this course is not the depth (as it is actually the same as the PADI Deep Diver specialty) but the ability to extend the bottom time on those depths which seem to have a very short ‘No Stop Limit’. Diving to 30 metres is a great example whereby the using the TEC 40 philosophies, it could increase bottom time by up to 50%.
We offer this as either a four or five-day course. The four-day course is an intensive course with time allocated in the evenings for theory sessions, and is ideal for those with previous ‘twin set’ experience. The five-day course allows more in-water time and spreads the theory sessions throughout the day, and is more suited to those who have no prior experience of ‘twin set’ diving.
