About

Will developed a passion for diving when he learned to dive in Cornwall, UK. He was quickly captivated by the abundance of shipwrecks along the south coast and developed an interest in technical diving. By 2005, he became a TDI Advanced Trimix Technical Diving Instructor and CCR diver. Will is a full-time technical diving instructor who has been based on the Gili Islands in Indonesia for 20 years. He began by managing Blue Marlin Dive Tech and spent six seasons as the trip director for a Komodo liveaboard. He currently has over 7,000 logged dives, 5,000 of which are technical dives, with 4,000 of those conducted on CCR. In 2005, 2008, and 2010, he set Guinness World Records for the longest open saltwater scuba dive, the longest of which lasted just over 48 hours.He has been actively teaching CCR since 2009, and in 2011, he began exclusively teaching the JJ-CCR. Since then, he has accumulated over 3,000 hours on the unit in a variety of demanding conditions and environments. In 2013, he became an Instructor Trainer for TDI at all levels. In 2014, after two years of research and training, Will Goodman and his team set the world record for the deepest dive in the ocean on an unmodified CCR, taking his JJ to 290m without incident. He then presented his findings as a speaker to an international audience at ADEX 2014. In 2019, Will founded Black Water Tek and became Indonesia’s factory-approved service technician for the JJ-CCR.

Across 40+ reviews, Will Goodman's reputation is built on being an exacting but generous teacher — students consistently describe clear, direct feedback that makes even a complex rebreather feel manageable within days, alongside a willingness to go well above and beyond for people training under him. More than one review highlights how humble he stays despite the depth of his experience, and the training itself gets described as genuinely rigorous and challenging — the kind that leaves you with real, lasting confidence rather than just a certification card.
