Usually, our Level 4 course is held during our international holidays because of its extended duration and the specific challenges it presents in the UK. Nonetheless, if you opt to pursue it locally and can dedicate the required time, we’re adaptable and can cater to your preference. Were blessed here in Cornwall with our own Inland dive site that has the depth to achieve and pass this course.

This course is meticulously designed to elevate a freediver’s training beyond the AIDA 3 Freediver level. Tailored for those aspiring to pursue freediving beyond a recreational level, participants will delve deep into the techniques, knowledge, and safety protocols essential for deep freediving. This encompasses practices such as exhale diving and mouth fill equalizing. The curriculum encompasses various freediving disciplines, including Static Apnea, Dynamic Apnea, Constant Weight, and Free Immersion, with a primary emphasis on Constant Weight.
In addition to in-water skills, students will explore full-body stretching, lung stretching, cross-training, and dietary considerations, all aimed at optimizing their freediving progression.
Upon certification as a level 4 freediver, individuals acquire the capability to assist on AIDA certification courses, often attaining an ‘Assistant Instructor’ designation.

Hayley Hughes9 November 2025 Great swimming experience. Very atmospheric place. Kayleigh Heselden26 September 2025 Had such a wonderful experience here for my birthday, so remote and untouched full of tranquility, definitely be going back and would recommend ☺️ Mimi Milne21 September 2025 Had the absolute best time on a wild spa package today. Is such a beautiful spot completely hidden away. We were totally left to ourselves but know Olly was there if we needed anything. We will definitely be back and 100% reccomend. Michael Thomason16 September 2025 I did the Aida 1 and 2 two day course with Oli as an instructor and thought it was excellent. He's a brilliantly engaging instructor who is clearly a world expert. He focusses massively on safety which, in fact, is a set of skills that allow you to dive better: more efficiently and for longer. It was so comprehensive that I feel confident that I can dive proficiently at depth and I was a complete beginner when I started. The environment at the pool is amazing with Sauna and hot tub and a great cozy classroom. The kit was top class too. I'm looking forward to applying the skills to spearfishing and foraging in the future and will certainly return to Delphy for more practice and courses. Beryl Strachan15 September 2025 Enjoyed a really lovely spa package recently, had tranquil swims in the clear water, in scenic and natual surroundings. Then 15 mins in the swirling hot tub and a brief time in the sauna (with a view!). Perfect! A hot shower followed, also a hot chocolate made by the very welcoming, informative Oliver. Will be back at some point I'm sure to this unusual venue. Thank you for the experience, not one that I have had before! Vector Fingall14 September 2025 Oil’s knowledge and delivery of the AIDA2 course is extraordinary. With grim weather conditions and totally inexperienced students, he has given us the confidence, experience and information needed to spearfish safely and well! We focused on challenging freediving techniques to support our time hunting fish. He’s a lovely guy to be around too! Calum Ryan14 September 2025 Fantastic experience, our group was initially down for the two day spearfishing course, however, the weather wasn’t playing ball. So instead we changed the course to the freediving course. This actually worked out much better for us, giving us a much better baseline for spearfishing. By the end, we were going much deeper than we originally would have and I feel much more confident to get out in the water and catch some fish! Pamela Lewis13 September 2025 Booked the spa package, what a beautiful place to swim and relax. The water was crystal clear. The hot tub and sauna are both great and the hot chocolate after was lovely. Wish I lived closer . Ryan Davey5 September 2025 Completed the 2 day Aida Course, Oli was fantastic, very knowledgeable Kate Chadwick5 September 2025 Did the AIDA 1&2 freediving with Oli and Grant. Great hands on training and lots of patience and practice. Quality equipment and a beautiful place to learn.
While you’re booking AIDA 4, you might want to pre-book some additional private training to enhance your skills even further.
