Poseidon Diving is a small, family-run dive operation based in Rawai, Phuket, run by Klaus and his team aboard their own dive boat, the Poseidon, a converted fishing vessel carrying up to 15 divers. The center emphasizes a relaxed, personal approach with small groups (maximum 3 divers per guide), no time pressure, and German-, Spanish-, English- and Thai-speaking instructors. Day trips explore reefs and wrecks around Phuket, and the center also organizes multi-day dive safaris to Phi Phi, Koh Haa and further afield to Indonesia (Bali, Raja Ampat, Celebes Sea). PADI dive courses cover the full range from Discover Scuba Diving through Open Water, Advanced Open Water, Deep Diver, Nitrox, Emergency First Response and Rescue Diver. All day-trip prices include hotel pick-up and drop-off, weights, tank, towel, fresh fruit, lunch and drinking water.
