    Episode 221 Narked at 90 Brent Hudson & John Routley
    Feb 16 2026
    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.

  • Episode 217 Jason Pritchard

    Episode 217 Jason Pritchard
    Dec 22 2025

    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.
