For the practitioner who wants to internalise this — not just learn it — and start changing the diving culture around them. Small cohorts, facilitated, real conversation.
The Human Diver builds training, language and community for the divers and dive professionals who refuse the bad-apple narrative.
Built for the divers who already know.
You have read the books, listened to the podcast, done Essentials — and you are hungry for the next layer.
You want to spend two hours each week for ten weeks with peers who are taking this as seriously as you are.
You teach, you lead, or you are the person other divers come to with the awkward questions.
You want the work to land in a way that changes how you actually behave on the boat — not just how you talk about it.

“Before this programme I thought I understood why diving incidents happened. Afterwards I realised I had been looking at the wrong thing entirely. The shift in how I now brief, debrief, and respond when something goes differently to the plan is not subtle — it is fundamental.”

Sector: Technical Diving

“We have had safety consultants before. Gareth is not a safety consultant. He changed how our entire leadership team thinks about what an incident actually tells us. Our near-miss reporting increased by over forty per cent in the six months after the programme.”
Head of HSE, [Organisation], [Sector]
Sector: Corporate and Industry

“The best keynote I have seen in fifteen years of conference attendance. He did not tell us what to think. He gave us a framework we couldn't unsee.”

By the end of ten weeks, this work isn't language you reach for — it is how you read a situation, how you brief a team, how you debrief a problem.
Focused on what HF in Diving is and how it directly applies to you, leading to better, safer dives and divers.
Psychological safety creates the environment for speaking up. Just Culture allows learning to grow following an 'event'.
We make decisions all the time. But many of them are unconscious. Learn how to make more effective decisions.
Situation awareness is a bit of a buzzword, and means different things to different divers. Learn how to build and maintain it.
If communication was that easy? Communication sits at the centre of effective teamwork and instruction. Learn tools you can use straight away to reduce miscommunication.
Teams exist at all levels in diving. Maybe not formally, but having the clear goal of everyone surfacing unharmed should be core to everyone. Learn UNITED-C and DEBrEIF tools.
In practice, every instructor is a leader, and every student is a follower. This module brings this to life inside and outside of instructional and training dives.
The errors we make are shaped by the context we are in. Change the context, and we are less likely to make errors. Learn how to design your diving to make fewer errors, leading to better dives.
This module provides an insight into the Learning from Emergent Outcomes (LFEO) programme, giving you critical and important skills to learn from events, not just point at the last to touch it.
Real change happens when we take learning and apply it. This module is about reflecting on what you've learned and what you will personal change. Setting goals for the future.
Places limited so the cohort stays small enough for honest conversation.

Work through the course. Do the exercises. If you have given it a fair effort and it has not changed how you think about diving — we will refund you in full. No forms, no friction. The guarantee is meaningful because the work is meaningful.
Cohorts run three times per year, across different time zones. The next start date is shown on the booking page — places are limited so cohorts can stay small.
One 120-minute live session, plus around 30 minutes of reading and exercises between sessions. Sessions are recorded for time-zone reasons with focus on the live sessions.
Not necessarily. The Masterclass assumes the vocabulary Essentials puts in your head. If you have come through significant practitioner work or teaching, talk to us.
Because most of the learning happens between people, not from a screen. The ten weeks are designed to put a small group of serious practitioners into honest conversation.
The Masterclass is where the work stops being something you have studied and starts being something you do. Ten weeks. A small group. Honest conversation.
Human factors, non-technical skills and learning from emergent outcomes for the divers who refuse the bad-apple story.
