I think what Eoin means, is that he may be mental to start diving caves himself, as he doesnt ever want to end up in the situation that Artur found himself in. I know this because im Eoins buddy and weve decided that were going to do the cavern and cave courses with Arthur*, but we have allready swore to ourselves that it will be sea caves only, and none of the freshwater stuff Artur does too.
(I know the same can happen in sea caves too, but the viz does look a bit better in his sea cave photos!)
We both rate Artur highly and have followed his dives for a few years now, and we both know that even if we never dive a cave again after the courses, that we will still have learnt loads from our time with him.
*when both of our job situations settle down.
