Andre Longchamps is the name that keeps surfacing when divers on Ko Lanta ask around for a recommendation — one reviewer who did their cavern course with him described him as someone they could strongly recommend without hesitation, and a separate community recommendation called him simply the best instructor to dive with on the island. OK Club, the centre he runs, carries one of the strongest overall reputations of any technical operation in the area, and Andre's individual name recognition tracks right alongside it.
