Well, after all those indecisions - I've finally done it.

The deep - didn't seem deep - and I went into a semi-type cave
The UW nav - I got off-track LOL
The night - wasn't so good - got a bit claustrophobic
The wreck - absolutely fantastic. Want to do that again - AND I can penetrate it (those of you that do wreck diving, don't worry, this isn't complete penetration, as most of the bits that you can go into here are still classed as open water - if that makes sense
The Peak buoyancy- i was jumping through hoops

next stop - Rescue
