Thanks Ken, lots of useful information. How does joining a club work? Do you pay a monthly/annual fee, and would most of the diving take place in a pool (other than the excursions you mention)? At the moment, I only have my own mask, so is there the option to use club kit? Thanks in advanceTo be blunt you are a complete beginner and probably have no real idea about many aspects of diving. Before contemplating getting work as a divers you ought to get proper experience, not endless courses.
Diver education is a bit of a pyramid scheme resulting in lots of apparently qualified “professionals“ chasing very few jobs.
If you want to get experience join a club Find a club or centre many run club trips to warm destinations which would more than double your dive count. my branch as one in May, though you’d most likely not be experienced enough by then and better to gain experience gradually for a few month first.
