Question 1

How many technical dive centres are there in Phuket, Thailand?

Accepted Answer

TecDiveTools lists 6 dive centres teaching technical diving in Phuket, Thailand. The directory is not a census — it lists the centres we have been able to verify, and grows as more are added.

Question 2

Why learn technical diving in Phuket, Thailand?

Accepted Answer

Phuket is the Andaman base for deeper offshore sites and trips to the caves of Khao Sok and Krabi. Thailand gives you the widest range of technical training in one country. Koh Tao, in the Gulf, is one of the world's busiest dive-training islands, with deep pinnacles nearby and offshore expeditions to 65–75 m wrecks. On the Andaman coast, Phuket is the base for deeper offshore sites and trips inland to cave sites. And the caves are genuinely demanding: the limestone caves of Khao Sok National Park, the deep sinkhole at Sra Keow near Krabi and Song Hong in Trang.

Question 3

Which technical diving agencies can I train with in Phuket, Thailand?

Accepted Answer

TDI (6), IANTD (3), PADI TecRec (1), RAID (1) and SSI XR (1), counted by how many of the 6 dive centres listed in Phuket, Thailand teach each. 3 teach more than one agency. The agency sets the standards and issues the card; the centre sets the price and schedule.

Question 7

When is the best time of year for technical diving in Phuket, Thailand?

Accepted Answer

Thailand's two coasts have opposite seasons. The Andaman coast (Phuket, Krabi, the Similan Islands) is best from roughly November to April, and the Similan Islands national park closes for the monsoon from mid-May to mid-October. The Gulf (Koh Tao, Koh Phangan) dives all year, with its wettest weather around November and December. Heavy rain can reduce visibility in the caves.

Question 8

How warm is the water in Phuket, Thailand, and what do technical divers wear?

Accepted Answer

Around 27–30°C in the sea all year; a 3 mm wetsuit is usual, but long decompression still cools you, so many technical divers add an undersuit, a thicker wetsuit or a drysuit shell for multi-hour dives.
