Join the HFiD: Masterclass seriesJust imagine yourself after this course!
By the end of this course you will have:

Improved Awareness
The awareness developed in the Masterclass goes beyond that created via the initial theory of Essentials and the experiential awareness in the Applied Skills class. The awareness developed here allows you to abstract the concepts, ideas and tools to many different aspects so that you can enhance your performance as a diver and improve your diving safety.

Deeper Knowledge
With six times as much time spent on knowledge transfer, and three times more than the Applied Skills class, the Masterclass digs much deeper into topics, giving you lots of examples of joining the theory with practice. You will also learn from other members in the class as you share your stories and reflections, bringing the theory to life. This is an applied knowledge Masterclass. You won't just be better than yesterday as a diver, this applies to life in general.

Critical Insights
You will see the world through fresh eyes - not just in your diving but your 'normal' life too. This course isn't just about enhancing your diving performance by building knowledge and awareness, it will give you skills and insights into how to be more effective in your professional and personal life too. Deep discussions and reflections will allow you to see how changes can be applied beyond just your own diving or diving instruction, but much wider into your personal and professional lives.
But most of all:
You will have developed a deeper knowledge that allows you to meet your goals of creating positive change in your own diving, by enhancing your performance through deeper knowledge development. You will have the tools, the knowledge, and the motivation to make a positive difference in the diving world.
You will be better than yesterday.

Tim Andro
As a leader of a multi agency public safety dive taskforce and team. I have to say this class hits on a lot of very important topics that help team leaders and members understand how to be great leaders and follower. All the while, creating an environment to fail safely in.
⭐⭐⭐⭐⭐
Laurie M. Penland
As science divers, a huge risk is to become too task focused. From better briefs and checklists to improved situation awareness and just culture, this training provided relevant information on how we can do better to mitigate this risk.
⭐⭐⭐⭐⭐

I wholeheartedly believe that there is not a single person on this planet that would not benefit from taking this course. What I keep telling people who I would like to take this course is, that this is by no means a course that is focused on diving. It applies to everything and everyone, every workspace, every recreational activity, and any social interaction.
⭐⭐⭐⭐⭐
Robin Kirkpatrick
"Human Factors in Diving" as promoted and presented by Gareth is something that training agencies around the world should seriously consider adopting and doing so from initial dive training and throughout all dive progression. It is a 'culture changer' in the most positive of ways and its adoption will undoubtedly make better, safer and more resilient divers.

Diving takes place in an inherently hazardous environment. Technical skills (buoyancy, propulsion, trim, and equipment handling etc) and technology (CCR, scooters, dive computers...) will only get you so far in terms of enhancing your underwater performance - no matter how shiny the piece of equipment!!
We take our brain on every dive, and this HFiD: Masterclass gives you deeper knowledge to make better decisions, communicate more clearly, and be more aware because you've gained practical knowledge that is applicable and actionable tomorrow.
Waiting will not solve your gaps in knowledge and there will never be a perfect time to start than now.
So why not start today and be better than yesterday.
