Susanne S.
"The human factors course was an extraordinary experience. First, it helped to create a friendly environment to share and learn. During teamwork, the special moments were unexpected situations that forced us to replan and communicate effectively, similar to real diving and no diving moments. I strongly recommend this course for divers and no divers!"

"I found this training to be among the most excellent I've partaken in.Â
The classroom days were fun and engaging, structured in such a way that we were kept on our toes but never rushed.
I would recommend this training not only to divers, but to anyone in possession of a brain who would like to work effectively with other people!"

Paul T.
"This program brings everyone, no matter what background or experience to the same level. It forges teamwork in minutes rather than days, or weeks, or even months. Explanations of complex ideas and statements were made easy to understand so that retention is assured.
The Human Diver is valid for every diver, no matter whether that be an Open water Diver or a Trimix Rebreather Cave Instructor Trainer."

"All the aspects of the course were known to me. I did Essentials, the 10-week program, read most of the blogs and several of the 'reading materials'. Still this was an eye-opener. It's like learning buoyancy, trim and proper movement in the water column. You can know the theory, train and apply all the skills, but until you get yourself filmed and watch it several times, you can begin to understand how it works and how to improve working on yourself. So it was like that film."

"This course is a must for any organisation whether involved in diving or not, human factors transpose in to all teams and can help provide the framework for building and fostering a just culture within any organisation"
âââââ
Nevo V.
"I came to this course after taking the 10-week series a few months before. This course helps turning theory into practical tools through a process of trial and error which puts a mirror on your own and the other studentsâ behaviours and reactions when working in a team. Afterwards they are analyzed together to create awareness of those behaviors, so making it easier to identify them when they reoccur in the future."
