Technical, cave and rebreather instructor Lanny Vogel will be presenting some stories, thoughts and how we can do better as he focuses on what we can learn from cave and technical accidents when he takes to the Tech Stage at the GO Diving Show in March.
Lanny is the owner and lead instructor of Underworld Tulum (www.underworldtulum.com), a purpose-built dive centre in the heart of Mexican cave country with bespoke accommodation for divers. He has been diving for over 25 years and first qualified as a technical instructor in 2005.
He specialises in cave, technical and rebreather training in the beautiful Mexican caves, is also the founder of Cave Camp, and is part of the ‘CREER' line and safety committee in Mexico, a community organisation that works to promote safety, conservation and maintain hundreds of kilometres of cave line in the region.
Before diving full time, he was a Commander in the Royal Navy with some interesting roles in submarines, surface ships and on land operations in Afghanistan and Iraq. He will be joining the instructor team of www.thehumandiver.com in early 2025, drawing on experience from cave diving, mountaineering and some interesting military risk management and strategic planning roles. He is probably happiest when scootering on a rebreather in epic cave, and when not in the water, he can most often be found with a book in one hand and one of a growing pack of rescue dogs in the other.

The GO Diving Show
The GO Diving Show – the only consumer dive and travel show in the UK – returns to the NAEC Stoneleigh on 1-2 March 2025, just in time to kick off the new season, and promises a weekend full of interactive, educational, inspirational and fun content.
As well as the Main Stage – this time headlined by TV star, author and adventurer Steve Backshall, making a welcome return to the GO Diving Show after a few years away, along with NASA-trained NEEMO Aquanaut and Head of Scientific Research at DEEP Dawn Kernagis, fellow TV presenter, author and perennial favourite Monty Halls, and the dynamic duo of explorers Rannva Joermundsson and Maria Bollerup, who will be talking about their recent Expedition Buteng in Indonesia – there are again dedicated stages for UK diving, technical diving, underwater photography and inspirational tales.
Along with the stages, there are a host of interactive elements – the ever-popular Cave, the giant trydive pool, the immersive virtual reality tech-wreck dive, breath-hold workshops and lining-out drills and, new for 2025, your chance to try your hand at wreck mapping with the Nautical Archaeology Society and their ‘shipwreck' – all scattered among an ever-increasing array of stands from tourist boards, manufacturers, training agencies, resorts, liveaboards, dive centres, retailers and much more.
This year also sees the NoTanx Zero2Hero competition taking centre-stage. This competition, aimed at newbie freedivers, will see an initial 12 candidates undergo training with Marcus Greatwood and the NoTanx team in London in late-February. Then five selected finalists will compete at the GO Diving Show over the March weekend, including static apnea sessions in the pool, to find the overall winner, who will get a week-long trip to Marsa Shagra Eco-Village, courtest of Oonasdivers.
