Catherine Martineau has turned her career around and now teaches the BathysMed method. This is an integrative approach that combines diving science with relaxation and mindfulness practices. Its effectiveness has been demonstrated through four clinical studies showing significant psychological and physical benefits. Participants experience reduced stress, improved emotional regulation, and an enhanced sense of inner calm. Understanding how and why we do, what we do (HF), supports this method.

You will have built the foundations for a personal culture of learning, along with gaining knowledge and awareness of how to influence the diving industry to be a safer, more enjoyable place. You will be a leader, even if you don't hold a title that infers leadership. You will be a trail blazer when it comes to improving the learning surrounding unexpected and unwanted events in diving.
You will be better than yesterday

As a previous recreational dive instructor, now technical diver, and leader of non-diving organizations, I can whole-heartedly recommend this course as foundational to your diving, your career, and your personal life. The principles within, if you are attuned and open to learning, may just postitively influence your character across all domains.
⭐⭐⭐⭐⭐

It would be beneficial for anyone to take this course because it's not only extremely informative and well-articulated, but also because it forces you to reflect on your personal experience on the topic. Our reflections then allow us to identify areas of mistakes or things we are doing well and therefore improve our instruction.
⭐⭐⭐⭐⭐

As a technical and scientific diver, the course has opened my eyes to the many facets of human factors and deepened my understanding of how accidents unfold, even when everything seems like business as usual. Certainly a course that holds a lot of value for any diver.
⭐⭐⭐⭐⭐

Very well put together course. Having done the Level 1 course prior to the Essentials, it is appealing how the concepts have been condensed without losing the plot or the essential details without oversimplification. Well organized in a stepwise fashion to make concept retention natural and illustrated with an excellent case study and additional resources.
⭐⭐⭐⭐⭐
There can be large egos involved at the higher levels of technical & CCR diving. Being able to put those egos aside to create a safe space to ask questions, challenge current processes, & recognize when an issue, no matter how minor, arises & what it's effect on both an individual diver as well as the dive team is paramount.
As an aspiring technical team diver, I'd say this course provides a superb foundation to enable people to become better team divers, who think about their actions more carefully to the benefit of the team. And discuss those thoughts to help the whole team reflect and improve.
Getting insight behind the cause of mistakes and accidents in the diving world is extremely valuable as a recreational dive professional, because its giving me more insight into things to look out for both in myself and my students that could potentially create risk.
