Saltfree was founded in 2003 and is run by Sam Amps (nee Kirby). Sam is an AIDA International Instructor Trainer, a qualified teacher, a qualified PADI Course Director and a former Captain of the UK Freedive Team who has represented her country on numerous occasions.

If you would like to learn to freedive from scratch, or have done some diving but don’t have a qualification yet – visit our Freedive Courses page to find out how to get started. Our beginner course only takes a weekend.

If you already hold a freedive qualification and would like to come and train with us, our Freedive Meets page explains how that works. If you’d like to progress your diving, we run courses all the way up to AIDA Instructor level. Visit our Freedive Courses page for info on that.

If you’ve got any other queries – drop SaltFree a mail.

“I spent a day training with Sam in glorious south coast seas last summer. We managed to do lots of exercises, a fair few extended exploratory swim-throughs, and the day culminated with a 20m max dive. Sam was relaxed, good company and a terrific teacher, I’d recommend her to anyone.”–Steve Backshall, BBC Live and Deadly – Freedive Cornwall Training Day, August 2011

“Thanks to everyone, especially Sam, for making the course last weekend so relaxed and friendly. Can't wait for the next time.” –Graham, AIDA 2 Star, June 2012

“Just a quick line to thank you for a fantastic weekend. It was a great course and I gained a huge amount from it. Hannah was brilliant, friendly  and professional as an instructor, having her in the water made the difference between 5m and 16m. She made me feel that I was in good hands and was safe to dive deeper than I would otherwise have done.” – James, AIDA 2 Star, September 2011

“Always loved heading to Saltfree, Travelling from Ireland for either courses or competitions and after forking out on the travel the last thing I wanted was for the dive site to be blown out with big winds or bad weather so Chepstow was ideal in this regard. Luckily the sun shone most of the time I've been there so chilling after dives in the sun with a great gang who are now definitely in the friends bracket just friends I don't get to see as often as I would like.” – Feargus Callagy, Freedive Ireland, long time SaltFree Diver

“Regarding feedback - mine is quite simple - good clear instruction, excellent enthusiasm and very happy with the results!! Definitely coming down again soon!” – Tom Murphy, AIDA 2 Star 2011

"Doing the 4* has really helped with my technique. Sam is extremely knowledgable and was able to answer every question, even going into detail using medical textbooks! The in-water sessions were excellent for improving technique, especially mouthfill equalisation and rescue skills. Almost immediately after completing the course I did my first 40m dive. There's no way I would have been able to do this before the course; it's helped me overcome a barrier and I'm quite excited about the possiblities for the future." – Pete Barnes, AIDA 4 Star 2013


'I started Freediving by doing my AIDA 2* course with Sam at Saltfree in 2005. Since then I have become a competitive freediver on the International freediving circuit, and completed an AIDA Instructor course with Saltfree. Saltfree has given me a fantastic space to learn and develop my freediving.  If I were going to do it all again from the beginning I wouldn't change anything about my freediving education with Saltfree"– Liv Philip, UK Record Holder and UK Team Freediver


“80m deep, great set up, awesome safety equipment / people, and a pontoon so big you can jog laps to keep warm in the winter! There is nowhere like the emerald green depths of Chepstow.” – Tim Money, UK Team Freediver

"I have just completed the AIDA 2* course with Saltfree and it was an amazing introduction to the world of Freediving. Everything was very professionally setup and run but also very friendly and relaxed, perfect for starting my Freediving adventure" – Dan Edgar, AIDA 2 Star 2012

“A fantastic way to spend a weekend, being educated, inspired and welcomed to the challenging world of freediving. Reaching that plate’s a great feeling!”– Rich Minshaw, AIDA 2 Star 2012
