Course Schedule

The schedule for the PADI Advanced Open Water course is flexible, and personalised depending on the elective dives you choose. PADI standards stipulate we can conduct 3 Adventure training dives in any one day.

A typical schedule looks like this

Day 1Orientation, Knowledge Development, PADI Adventure Dives

We meet at 09.00 on Day 1. Your PADI Instructor will conduct a short Orientation including completing some paperwork and a PADI Medical Statement. This is the time we will discuss and choose the three elective dives you wish to make.


Unlike the PADI Open Water course there is no exam. Instead each Adventure dive has a knowledge review. You will use the manual to complete the knowledge review before reviewing this with your Instructor. With some Adventure dives there are also some ‘land rehearsals’ prior to boarding the dive boat.

After lunch you will go out on our dive boat and complete two of your Adventure dives. The boat departs around 12.30. Typically on the first day you will complete the Underwater Navigation dive which is mandatory.

You will also complete a second Adventure such as PPB, Fish ID, Search & Recovery or Underwater Naturalist.

The Night Dive is the most popular elective dive in the Adventures in Diving Program. We schedule Night dives every second evening and assuming you choose this elective we will meet at 18.00.

We time our trip to the dive site to coincide with the sunset, ideally aiming to be in the water just before the sun completely goes down. This way the first few minutes of the dive, whilst you are becoming comfortable are a little easier as we are not in total darkness.

Night diving is an amazing experience. You will see some species of marine life you have seen during the day light hours actually sleeping including the Titan Triggerfish.

Other species such as hermit crabs and nocturnal stingrays are out foraging in the sand for food, Cuttle fish glow in your torch light and moving your arm slowly will reveal fluorescent phosphorescent plankton glowing in the darkness.

You will also see Barracuda hunting for small fish and if you’re lucky you may even see them catch their prey in the light of your torch.

Day 2Koh Tao PADI Advanced Course – Adventure Dives and Certification

Up bright and early, our dive boat departs at 07.30 for the highlight of the PADI Advanced Open Water course, the PADI Deep Adventure Dive and the first opportunity for you to experience Nitrogen Narcosis!

We will visit one of the deeper laying Pinnacles such as Chumphon Pinnacles or South West Pinnacles, two of the best ‘advanced’ dive sites around Koh Tao. You will descend to a maximum depth of 30 metres and your Instructor will demonstrate the effects of pressure and how it affects us at depth.

You will also get to see a greater diversity of marine life than at some of the shallower dive sites. Some of Koh Tao’s larger marine species such as Giant Barracuda, King Mackerel, Giant Grouper and sharks typically hang out at Koh Tao’s deeper sites.

If you are lucky, you may even get to see a mighty Whaleshark!

You will then complete a second Adventure dive on the journey back to Koh Tao. This is your final elective dive and amongst the more popular choices of dives are; Wreck, DPV and Night diving.

Exploration, Excitement, Experiences

Here is a more detailed look at the PADI Adventure Dives we currently offer at Crystal Dive Resort as part of the PADI Advanced Open Water course.

Deep Dive

Experience Nitrogen Narcosis and the affects of pressure at depth. Find out which colours we lose first, and why your air consumption increases.

Feel the subtle effect narcosis has on your senses and understand the physiological effects of deeper diving. Dive planning for Deep dives requires additional safety procedures which you will learn.

You will plan a dive to a maximum depth of 30 metres, gaining valuable dive experience whilst under the supervision of one of our experienced PADI Master Instructors.

Extending your dive limit to 30 metres will also mean you are certified to dive a greater variety of dive sites anywhere around the world.

Underwater Navigation Dive

Learn how to estimate distance and how to use natural features to navigate underwater. We will teach you correct positioning and handling of a compass and how to use a compass to navigate a reciprocal heading.

You will finish by successfully navigating a square. You will feel much more confident in your ability to find you way underwater after this dive.

Peak Performance Buoyancy (PPB)

Buoyancy is the most important skill a diver needs. Better buoyancy means more control and improved air consumption.

Good buoyancy allows you to become a safer diver and avoid damaging the marine environment. The PPB Adventure dive will teach you how to better streamline yourself whilst diving.

As well as improving your air consumption we will practice hovering and swimming techniques. You will be amazed with your improvement after this dive and how much more effortless your diving becomes.

Night Diving

Drop into a whole new world and watch it come to life under the glow of your torch. The Night Adventure dive is the most popular elective dives on the PADI Advanced Open water course. We will teach you light handling and communication techniques plus entry and exiting in the dark.

We will also ask you to navigate a reciprocal heading, a skill you have mastered during the day, as part of the Underwater Navigation Adventure dive.

You will see some species of marine life retiring for the night, whilst others such as crustaceans and mollusks venture from their day time hiding places for night time feasts.

Wreck Diving

Interested in excitement and exploration? Take a fascinating look into the past with the most popular choice for an Adventure dive on Koh Tao. You will learn how to plan wreck dives that are deeper than 18 metres as well as all the necessary equipment considerations.

You will also learn how to avoid potential hazards common to wrecks including entanglement and the highlight is a completing the dive on the HTMS Sattakut.

Search & Recovery

For the more practical minded and task orientated diver the Search & Recovery Adventure dive is a must do!

Learn how to tie a variety of different knots, operate lift bags to bring various objects to the surface and use a compass to perform underwater searches. The Search & Recovery Adventure dive is challenging but lots of fun!

Diver Propulsion Vehicle (DPV)*

DPV’s are a great way to see more of the dive site. They scoot you through the water, allowing you to glide over coral reefs or around Wrecks. During this dive we will teach you correct entry, exit, descent and ascent techniques with a DPV.

You will also learn how to perform manoeuvers underwater as well as the correct safety techniques. For divers that like excitement, the DPV Adventure dive is for you.

**Additional 1,500 THB for DPV hire

AWARE – Fish Identification (Fish ID)

Have you ever been underwater and asked yourself ‘what is that? The PADI Project AWARE Fish Identification Adventure dive will help you with the basics, so next time you will know the answer to the question. Being able to recognise the marine life makes your diving so much more interesting and fun.

The best part about this dive is the knowledge and skills you learn can be used on every scuba vacation because once you learn the main fish families and characteristics you will be able to figure out the species you see all over the world.


Enriched Air – Nitrox

Want to spend even longer underwater. Why not enriched your dive experience and learn how to use Enriched Air Nitrox as part of you PADI Advanced Open Water course.

The Enriched Air adventure dive teaches you how to analyse your Enriched air fills to determine the oxygen content in the blend. We will also show you how to verify cylinder content data and of course execute a dive on Enriched Air.

Underwater Naturalist

The greater understanding you have of the aquatic environment the more you will savour the sights you encounter. Go beyond simple Fish Identification. On the Underwater Naturalist Adventure dive we will teach you how to locate, observe and identify fish, animals and plants.

Boat Diving

Here on Koh Tao 99% of all dives we make from a boat. The Boat Adventure dive teaches you specifics about dive boats including correct terminology, emergency procedures, safety equipment and correct entry/exit techniques.
