First went to Only One with Freedive UK when we used the platform for a day whilst out in Sharm in April. Facilities were great and Marco, Chiara and Gus very welcoming and as a consequence I extended my trip and spent 5 days training with Gus. As a result I then returned again for a 2 week training trip in May /June training with both Gus and latterely Marco for the deeper work.
Gus, with whom I spent most of the time with, is an excellent trainer - and I mean REALLY excellent. He has a true and infectious passion for freediving and this makes him a pleasure to spend time with. His techniques and insight are very valuable - he also has strong credibility given his own impressive depth work ( doing over 100m at the time of writing).
I worked with Marco on specific equalisation techniques and again his instruction is really great: insightful and passionate and a pleasure to spend time with.
In the end I significantly increased my Personal Bests in depth ( free immersion and constant weight) as well as static.
Facilities are good - there is also a cool Italian cafe next to the centre which is a very mellow little spot.
In summary when you are training for freediving you have to 100% trust in your instructors for all the obvious reasons - it was easy to trust these guys and thats the most important thing.
If you are an intermediate free diver looking to improve your PB this is the place to be!
