Tech Diving Information


Whilst there is a lot of good tech diving information on the internet, you often have to search far and wide for it.


The aim of this website is to bring it all together so that divers can find out a little bit more about whatever aspect of tech diving interests them. It doesn’t matter if you are an experienced tech diver or a recreational diver that has an interest in learning what technical diving is all about.


A good starting point for recreational divers can be found here

Obviously, there is no substitute for proper training in tech diving. You cannot learn to do physical tasks underwater just by reading about them. But it’s always good to brush up on theory and refresh your knowledge on a range of topics. There is a wide range of subjects to delve into: diving physiology, decompression theory, dive planning and diving procedures, equipment configurations, new equipment on the market, diving incident reports, and human factors in diving.


You’ll also find compiled lists of scuba diving apps and books, and Youtube playlists full of diving documentaries and books within the site.

The more you learn about technical diving, the more you realise that other divers may do things differently from how you were taught. There isn’t necessarily a right or wrong way of doing things, and it’s interesting to learn and understand the different approaches.


The important thing is that the diving procedures you adopt with your own diving are considered to be safe. You’ll find a lot of different approaches to things in some of the Youtube playlists of skills demos and equipment configurations.

Articles and books on technical diving topics


In this section of the website, you’ll find links to articles on equipment configurations, diving physiology, decompression theory, dive planning and diving procedures, diving incident reports, and human factors. There are also links to a variety of websites- personal blogs, diving magazines, podcasts and Youtube channels, and popular dive forums. Useful and interesting books on tech diving are also listed.

Diving documentaries, skills demos, and tutorials


In the diving videos section, you’ll find Youtube playlists grouped into each subject area. Videos on diving physiology and decompression theory consist of lectures by diving doctors and researchers, often recorded at conferences. Some of the skills demonstrations are done by the author of this website, but there are links to many others, grouped by the training agency. This includes TDI, IANTD, Raid, GUE, ISE, UTD and SSI- XR.


There are also numerous videos on various aspects of rebreather diving, such as skills demos and unit-specific tutorials. Diving physiology as it relates to rebreather diving has also been included in this section.

Tech diving courses


Tech diving is an advanced form of scuba diving. Before training as a technical diver, you need to already be an experienced scuba diver. If you are thinking of learning technical diving or just beginning your training, you’ll find information on how to start out in technical diving, and how you can advance through the sport.


In the courses menu, there is an overview of how you would normally progress from course to course, and each course has its own page with more information. The author also provides a rundown of how one of their tech diving courses is typically run.
