Who is this masterclass for?
This class is for instructors and passionate divers who want to go beyond recreational diving — to understand what they see, offer richer experiences, or simply connect with the ocean in a more mindful way.
If you are passionate about diving, travel to top destinations, and feel like you’re missing something when it comes to understanding what you observe underwater, this class will give you a new perspective — no need to be a biologist.
For those who already love the sea but want something more — to interpret animal behavior, observe with intention, and turn every dive into a memorable, educational, and visually powerful experience.
What will you learn in the masterclass?
You’ll discover how to change the way you see underwater. When you learn to look with intention and understanding, every dive becomes a richer, more mindful, and transformative experience.
You’ll learn that you don’t need to be a biologist to begin to understand what you see when you dive. With a simple, visual foundation, you’ll start to recognize behaviors and connections that previously went unnoticed.
You’ll learn a clear and practical method you can apply on your very next dive to identify wildlife, read behaviors, and connect emotionally with the environment. Because understanding what you see lets you enjoy (and remember) so much more.
