OK, here's a list of what I consider to be essential and nice-to-have tools and spares for keeping your JJ on song. Feel free to recommend changes/additions and I'll expand it as necessary.

If this proves useful, I could augment it with some servicing details/photos.

Most of the o-rings are listed in a sheet that DaveT posted on CCRx (http://www.ccrexplorers.com/showthread.php?t=14098#post128986). I will try to get a more comprehensive list together with the BS numbers when I get a chance

good to see the list on here Nick but what was it that went kerplunk on your Far East trip and have you included it here?

Yes mate, major problem was the tilt valve in the ADV going tits-up. Fortunately, Simon Mitchell had a spare.

For a full list of 'issues' read the third post in the trip report (http://www.thediveforum.com/showthread.php?136-Bikini-Atoll-June-2012)

Nick, have you been on holiday in the far east? We must compare notes next time we meet up on Gary's boat.

It was the far west for me. I flew in via Honololu
