Tec 45

Tec 45 Course


The Tec 45 course picks up where Tec 40 leaves off and takes your training as a tec diver further and deeper. Explore new dive sites, stay longer and improve your dive skills!


Who should take this course?

The Tec 45 course takes your technical diving to the next level, training you to spend even more time underwater. You will be fully equipped to plan and execute staged decompression dives to a maximum depth of 45m, using any Nitrox mix from 22% up to 100% oxygen to add conservatism or to accelerate your decompression obligation. There is no time limit associated with the decompression you plan, meaning you can complete as much decompression as you wish, within the dive planning limits you establish during your course.


What will you learn?

You will practice and develop all of the skills that you learnt on your Tec 40 course, and you will also learn new procedures for dealing with foreseeable technical diving emergencies. 

Through four dives, you will build your confidence with deeper dives, and increase your comfort during longer decompression times, using rich nitrox mixes to accelerate decompression.


Where is the course held?

We can use inland dive sites, dives in the sea or a mix of both to complete the Tec 45 course. Local inland sites offer easy entry and training locations for the skills portion of the course. Locations such as Portland, Lyme Regis and Plymouth have excellent sites for you to take your final course dives on exciting local wrecks. If you fancy somewhere warmer why not enquire about taking your course on the wrecks around Malta & Gozo? We are happy to travel to you for the course, so please get in touch to discuss your options.


What scuba kit will you use?

A modified recreational set up isn’t suitable for the rigors of a Tec 45 course. For the Tec 45 course you will need a full twinset configuration, single decompression cylinder and other redundant equipment associated with decompression diving. A dry suit is essential if you’re planning on taking the course here in the UK.
