Q4 2023

MY DIVE BUDDY AND I planned to do a longer than usual dive one Saturday morning at Madison Blue Spring State Park in Lee, Florida. For several years and more than 100 cave dives together, we had built up our experience as a team and our time spent in this specific underwater cave system in northern Florida. We had slowly extended the duration and distance of our dives in this labyrinth of underwater tunnels that weaved throughout the karst limestone of the park, increasing our familiarity with the system while also practicing the skills that we had learned and continued to build on to be safe cave divers.

IN THE 1900s UMBERTO PELIZZARI was a young diver from Busto Arsizio, Italy, who was making headlines by breaking world records in constant weight and variable weight freediving. Needing an edge against his archrival, Francisco “Pipin” Ferreras, he sought advice on fins from a friend who was knowledgeable about innovative freediving equipment: Valerio Grassi, founder of Omersub.

Q4 2023

I’M ALWAYS AMAZED at what people will do for love. My girlfriend, who is terrified of the ocean, announced that she wanted to learn to dive and then accompany me on a trip to Raja Ampat, Indonesia. I was thrilled. We come from different backgrounds and always look for activities we can do together.
