Dive Buddy . . . I remember one trip many years ago, to Tortola. Our group was to dive Salt Island and go on to the wreck of the RMS Rhone. There were 4 of us from the UK - all BSAC qualified and the rest (approx 16 - 20) who were progressing their PADI "C Card" were all from a very large state in an even larger country to the North West. After pairing the four of us up, the Dive Master went on to explain that he had worked with the others the day before. He said his greatest challenge was to impress upon them that their "dive buddy" was not simply someone in the water who happened to be "in the same ocean on the same day!"
