Jim Warny started diving 21 years ago and soon got attracted by the technical side of the sport.
He built his first rebreather at the age of 18 and has continued since building and modifying several units. Cave diving and later on caving became his passion early on in his diving career.
He has participated in multiple expeditions in France, Italy and recently in the Huautla cave system in Mexico.
But when Jim moved to Ireland in 2004 he truly found his calling in the dark caves and resurgences in the Galway/Clare region.
Following in the footsteps of previous explorers Jim extended explorations in various sites amounting to many kilometres of new cave.
One of these being the longest sump in Ireland amounting in a 2.9Km swim.
He continues to be very active in the Irish cave/cave diving scene.
In June of 2018, he was part of the team of British cave divers who played a leading role in the Tham Luang Thailand cave rescue.
