The Advanced Deep Air Level 1 course is intended to introduce the basic recreational diver to extended range recreational diving (ERRD).

PSA has found a great divide between basic recreational diving and ERRD, and as such this course is aimed to gently introduce the diver to the philosophy’s and techniques of ERRD.

Advanced Deep Air Level 2 will introduce you to a more in depth look at inert gas narcosis, diving physics and pressure related maladies.

Equipment configuration involving large volume single cylinders and redundant alternative air supplies.

You would have already been introduced to the PSA training slate for underwater skills (unless level 1 was skipped, ask for details).

You will be assessed on your dive awareness and ability to control a dive profile.

You will be trained further in dive planning and management and be introduced to the "what ifs" of dive planning.

Advanced Deep Air Level 3 will introduce you to further kit configuration ideas such as large volume cylinders (18L and 20L), with dual outlets as well as double tank configurations both independent and manifold rigs.

During your class sessions you will be introduced to decompression diving techniques and decompression theory.

You will look at gas planning for all eventualities for you and your buddy.

Further dive equipment such as lights and higher volume BCD’s/wings will be shown and discussed.

In water you will be performing the skills on the PSA slate as well as being introduced to delayed surface marker buoy (DSMB) deployment techniques.

PSAI Deep Air Level 4 is designed to be the most intense of the deep air programs available in the UK.

We are aware that many divers dive to these depths on air without the appropriate training.

If you have been through the entire PSA Advanced Deep Air Program you will be aware how demanding the program is, and how easy it is not to be aware of what you are doing whilst air diving at depth.

The PSA basic Nitrox course is designed to introduce the recreational diver to an alternative to 21% breathing air.

During your time with us you will be shown both the advantages and disadvantages of Nitrox or enriched air Nitrox.

By the end of the course you will have covered the use of formulas used for calculating maximum allowable depth of any given mix, the equivalent air depth of a given mix at a given depth and how to calculate for the best mix for a given dive.
