My son and I had a try dive early in 2018. It was gentle and encouraging, we both subsequently signed up for the basic Ocean diver course. We have now had a number on dives when on holiday.
With Trident Club I am now progressing onto the next level, Sport Diver.
If you do not want to experience the uncertainty of an trying a dive with a holiday dive centre then I would recommend this club and it's attention to safety and competence.
