Ting-ting-ting-ting-ting-ting-ting! Someone, somewhere, had found something really exciting! One of the dive guides was tapping frantically on the side of his cylinder with his metal pointer. Ting-ting-ting replied my dive guide Opo, only to receive more frantic tapping in response. My pulse rate upped a few more levels in anticipation of yet another exciting find.
