Now at OCEANS you can get the chance to meet the team and get a taste of this new sport that combines freediving with caving and abseiling, but do so in a way that won’t have Health & Safety drawing sharp breaths.

Take the NoTanx Phreatic Diving Challenge: after a test of your flexibility, strength and self-control you’ll get a brief safety talk before being kitted out. You’ll attempt to wriggle along Squeezy Passage (a replica cave), ascend a 25m anti-abseil (or “prusik”) and test your relaxation skills in a final Static Apnea (breath-hold).

Prizes of Anchor dive-lights and accessories are promised for fastest times each day. The experience is free, but please book your slot in advance – email: info@NoTanx.com
