"Very grateful to Rob, Simon and all the other helpers for their teaching and guidance during the Openwater Diver course I completed recently.

The course was fun throughout and it was clear that safety was always the first priority. Iā€™d highly recommend Cardiff Scuba to anyone wanting to do their first Scuba course."

From Matthew Soanes, course taken May 2019

"One of the best (and not last) courses I have completed. Every session was fantastically awesome, whether in the pool or the quarry.

This has opened me to many more underwater adventures that I cannot wait to experience.

The instructors took safety and the course very seriously which made me feel more confident and secure during the course.

They were also such admirable and lovely people, which made the course extra enjoyable.

Thank you Cardiff Scuba!"

From Alexandra Radziejowska, course taken February 2019

"What an experience !
I rate Cardiff Scuba and the whole team 10/10 !

The experience I had with Scuba Cardiff has been amazing , from the day me and my partner started making contact to enrol until the very last dive as part of our Open Water Course !

Rob made everything simple, objective and super easy to understand. Also assisted every time we needed in terms of practice or just having a couple of questions...

Rob also made us feel part of a diving family/community, something that grew so much in the past weeks that actually made us book the Advance Adventure Diving course already and really making me think to drop everything and pursue a diving career.

Thanks again !

Legend Rob !

See you in 2 weeks for Advanced !"

From Ricardo Torrao, course taken February 2019

"I have had an amazing last couple of weekends learning to become an open water diver. Rob, Simon, Julia and the team are so passionate about diving and teach in a professional and friendly way.

The Cardiff Scuba team are a brilliant laugh, and I can't wait to see them under the water again. If you want to learn to dive, and have fun doing it, I highly recommend Cardiff Scuba. "
