"Having tried a dive some time ago I decided to go for Open Water Diver training with my three children (12, 16 and 17).

Rob and the team's professionalism, confidence in us and their calm approach to training was exactly what I needed to make it relaxing and enjoyable.

Happy to recommend them for any 1 to 1, mixed age or family group - superb instruction!"

From Paul Stephens, course taken August 2017

"This course provided me with the basic skills to get out and enjoy diving. I'd like to thank all the staff who helped make this such a fun experience. There is a lot to learn but you are in safe hands with the gang over at Cardiff Scuba.

Massive thank you to Rob who made our last Dive so much fun."

From Paul Vincent, course taken May 2017

"Absolute belter of a course, final dive was a great experience.

Could be more clarity on timings of the course but apart from that its spot on, good instructors, good people, thanks guys!"

From Charlie Sleddon-plant, course taken May 2017

"Was I apprehensive about diving? Yes. But as Cardiff Scuba will tell you: apprehensive is good. It shows you have respect for what you're taking on.

The team at Cardiff Scuba are amazing. I really liked instructor Julia. She was super helpful, although I didn't dive with her. Simon could not have been more accommodating. I did confined water with him, and felt brilliant afterwards. He just helped me to 'get it.'

Rob (or the Sergeant Major as I like to call him) is an absolute force of nature. He knew what I needed well before I did. Tough love, a calming word, a sit down on the naughty step, or a congratulatory shake of that gleaming head at a depth of 15 metres. He just knew what I needed to get through the dives, and for that I am truly grateful.

Today was hard, I won't lie. I made a lot of errors, a lot, and I stressed myself out a fair bit because of it. I trusted Rob absolutely when he said I'd have to repeat my final dive, although all I wanted to do was throw off the gear and mope. But had I done that I wouldn't have had the brilliant finale that I did.

Gliding through the water (ok, I might not have been that graceful), and doing it, Scuba diving, actually doing it and thinking, this is really, really cool.

Do I feel 100% confident now that I can shake a certificate at a dive master. Of course not. But I can progress and nail that buoyancy one day, respect the discipline and stay safe. And I really do have Cardiff Scuba to thank for all that."

From Steve Davies, course taken May 2017
