I've made more than 60 dives here with the vast majority in the south cove. N cove has a more interesting bottom though a much more difficult entry due to the washed out path. One can almost always find jade if you use a light to look in "out of the way" places. Strong surge is the norm and you work mostly in the shallows. Water entry and exit can be challenging. I've helped remove a two ton stone (the old days) and have found a 250lb rock on my own with lots of smaller stones. Good luck and enjoy!
