After such wonderful viz on the Undola our second dive for the day was at Barrens.  In near mirror finish seas we headed down, finding the anchor sitting upright on the sand in the split.  We were amazed at the viz, again a good 25m but cold at 15^oC.  We headed for the cave and chimney - a must do at Barrens.  I ventured out across the sand the viz was so good I could still see the reef from 20m out.  There were heaps of fish life - all the usual suspects at Barrens.  Leatherjackets of various types, old wives, groper, bullseye, a few different nudies, mowong etc.

Barrens is always a good dive, at 25m  deep we dived it comfortably on 37% Nitrox.  Even after diving the Undola and nearly 2 hour surface interval we were on the bottom for nearly 30 mins without going into deco.
