Thailand’s pre-eminent technical wreck divers, the MV Trident, will embark on their next expedition May 18. The “Closed-Circuit Divers Australia” group has booked many of the spaces on the tech liveaboard, but more spaces are still available.

The Trident’s Jamie Macleod says the trip will be both a mix of wreck-hunting and diving known wrecks as far south as the Malaysian border.

The trip runs out of the Trident’s home port of Koh Tao between May 18-26. The price is 75,000 all-inclusive except for helium. Booking details and contact information can be found on the Trident’s website.
