Sorry This one is not a Scuba cache 
for that you will need to venture inside and attempt "D(r)ive the Bus"
After a long day out diving in the freezing cold dam Killer Midget and I decided we wanted to put the cache up
I wanted to put it in the Cylinders but it seems those have been capped so we had to find another place and needless to say there is always a way to place a cache
Please post some photo's if you do any diving in the dam as it is always fun to see who all does other outdoors activities
