Episode 220 Sea-changers

In Episode 223 of the Big Scuba podcast, hosts Ian and Gemma are joined by TV presenter Miranda Krestovnikoff and her son, Ollie, to discuss the dynamics of a "diving family." The conversation explores how diving became a central part of their household, with Miranda's daughter, Emily, recently working as a Dive Master and Ollie emerging as an enthusiastic advocate for the sport. Miranda reflects on the natural progression of her children into diving, noting that while their upbringing made it almost inevitable, it was always rooted in a genuine, positive choice. Ollie's introduction to the underwater world was remarkably early, having first used a regulator at just three years old. He attributes his passion not only to his mother's career but to a shared family interest that included his father's love for snorkeling and his siblings' early certifications. This upbringing involved family holidays centered around diving clubs, allowing the children to build their skills alongside their parents. Now a teenager, Ollie is focused on encouraging other young people to overcome their hesitations and try the sport for themselves. Beyond recreational trips to locations like Grenada and the Philippines, the family remains active in marine conservation, frequently participating in underwater clean-ups with groups like "Neptune's Army." Miranda notes the welcoming nature of the diving community, which has consistently supported her children as fellow divers rather than just observers.   More about Grenada : https://www.puregrenada.com/ Madagascar with Operation Wallacea : https://www.opwall.com/location/madagascar/ Neptune's Army of Rubbish Cleaners : https://www.narcdiving.org.uk/   The BiG Scuba Podcast is proudly supported by Narked at 90 – "Beyond Technical."

This week on The BiG Scuba Podcast, Gemma and Ian chat to John Routley and Brent Hudson, the names behind Narked at 90. Brent and John are the founders of Narked at 90 and discuss their transition from hobbyist divers to leaders in the technical diving industry. They describe a history of innovating bespoke equipment, such as rebreathers and high-intensity strobes, often born from personal necessity and a drive for engineering mastery.  They both have experienced several "sketchy" situations during their extensive technical diving careers,. Their narrowest escapes involve equipment failures, entanglements, and high-pressure decision- making at depth. These experiences shaped their ethos that "copying skips understanding" and led them to focus on creating highly reliable, redundant equipment for the technical diving community Beyond diving, the duo detail their significant contributions to military defense projects and their vital role in producing ventilator control systems during the COVID-19 pandemic. The conversation highlights the importance of rigorous equipment testing, the evolution of diving electronics, and the value of recovering maritime artifacts to preserve social history. Ultimately, the founders advocate for professional mentorship and the continuous pursuit of safety within the niche global diving community.

This week on The BiG Scuba Podcast, Gemma and Ian chat to Jason Pritchard. Adventure has always been at the heart of who Jason is. Ever since His first dive back in 2009, he has been captivated by the mysteries of the ocean — from uncovering hidden wrecks to exploring the unknown. What started as curiosity soon became a calling. By 2018, Jason had earned his certification as a professional instructor, and today, as a PADI Course Director. He is very proud to help shape the next generation of divers through calm, safety-first guidance and real-world experience. For Jason, shipwrecks are the ultimate adventure. Each one tells a story, a blend of history, danger, and discovery frozen in time beneath the waves. Diving isn't just a pastime; it's stepping into another world, one where every shadow might hold a secret waiting to be found. In 2022, he faced his toughest challenge yet: a life-threatening bend caused by a PFO. That experience could have ended his diving journey, but instead, it reshaped it. It taught him discipline, patience, and a deep sense of gratitude for every single dive he makes. These days, Jason is diving deeper, exploring legendary wrecks like Scapa Flow, advancing his technical diving, and preparing for the next frontier: rebreathers. Jason recently become Sidemount qualified, adding another level of flexibility and efficiency to his dives. Beneath the waves, Jason finds peace, focus, and an endless sense of wonder. No matter how far he travels or how deep he explores, Jason will never lose sight of the simple joy of discovery. Every puddle, big or small, holds its own adventure. That spirit of curiosity keeps Jason pushing boundaries, chasing secrets, and living the ultimate underwater journey.
