Bit of a spanner, maybe:
Just try and get a try dive (even in a pool if that is all that is available) over here or at least before you shell out any serious cash.
It is quite rare I think but, even though I tried my damndest, put a lot of effort in and spent a fair bit of wedge, I learned that I’ll never be a ‘proper’ diver… my inner ear just couldn’t take it.
