Training Tips, Stories & Depth Insights from The Depth Collector

Welcome to the Archives of The Depth Collector.

This is my freediving blog, where I share stories, lessons, and training reflections, the kind of stuff that doesn't always make it into the books, but still matters.

Some articles dive into technique. Others explore mindset, equalization, or those unexpected moments underwater that leave me thinking.
