Open Water 30 Programme in Koh Tao
The Open Water 30 is a DPM-exclusive three-day package certifying beginners to 30 metres via SSI Open Water and Deep Adventurer. Six dives and all equipment are included.
About the programme
The Open Water 30 is an exclusive programme developed by DPM Diving that combines the SSI Open Water Diver course with the SSI Deep Adventurer recognition in a single three-day package. Unlike a standard Open Water course (which certifies to 18 metres), this programme takes beginners directly to a 30-metre certification depth on completion. The programme includes six dives in total, all dive equipment, dive insurance, a DPM t-shirt, a DPM diving mask and snorkel, a certified SSI instructor and all certification fees.
Small groups of maximum four students per instructor are maintained throughout. No prior diving experience is required. The pricing structure: the regular package value is 23,200 THB; the current offer price is 17,900 THB (saving 5,300 THB).
The offer also includes 50% discount on fun dives at DPM centres in Phi Phi, Nusa Penida, Gili Trawangan and Gili Air, usable once per location. A standard SSI medical questionnaire must be completed before entering the water. The Deep Adventurer component involves a supervised dive to 30 metres, which may require medical clearance if pre-existing conditions are flagged on the form.
Why do the Open Water 30 in Koh Tao
Because the extra depth this programme certifies you for is exactly where Koh Tao gets interesting. Conditions permitting, the deep dive usually takes place at Chumphon Pinnacle, 14 kilometres northwest, where granite towers climb from a 36-metre sand floor and barracuda schools and bull sharks patrol the blue, or at Southwest Pinnacle over its carpet of anemones and fusiliers.
The earlier dives stay on the shallow western reefs so buoyancy is solid before you go past 18 metres. Pinnacle trips mean a longer crossing, so they work best between March and September, when the Gulf is flat and visibility is at its 25-30-metre peak. Water temperature barely changes with depth here.
Dive sites are chosen on the day according to weather and sea conditions.

What is the difference between the Open Water 30 and the standard Open Water course?
The standard SSI Open Water course certifies you to dive to 18 metres independently. The Open Water 30 is a DPM-exclusive programme that adds the SSI Deep Adventurer recognition, extending your certified depth to 30 metres. Both take three days and are designed for beginners with no prior experience.
