Sidemount Instructor

In just the past few years, sidemount has gone from being an equipment configuration used by only the most elite cave divers to an activity in which a broad range of recreational and technical divers participate. There is no shortage of demand for Sidemount Diver training.

Although you could, theoretically, qualify to teach this course by making 25 or more technical sidemount dives, without specific training in how to teach, you risk students finding out your really do not know what you are doing. We see this happen regularly. It’s not pretty.

We assume you would prefer to offer a better quality Sidemount Diver program — one your past students will eagerly recommend to family and friends. We can show you how.

Additionally, as this is a TDI Technical Sidemount program, you’ll discover it offers students more value than similar recreational-level programs. Nevertheless, you can offer it to all your students, regardless of their certification level.

The staff at is uniquely qualified to teach this program. Not only have we logged several thousand sidemount dives, we literally “wrote the book” on sidemount diving. Specifically, we authored the TDI Sidemount Diver eLearning course, student manual and instructor guide.

You can’t do better than this.


To enroll in this course, candidates must:

A technical sidemount dive is any dive involving decompression, additional cylinders and/or overhead environments such as wrecks, caves or mines.
