The advanced course consists of five open water dives which introduce exciting new areas of diving. The duration of the course is two days. Two of the dives are mandatory - the deep dive and underwater navigation dive.

The deep dive*
We’ll take you right down to 30 metres. We'll make a test to see if you suffer any nitrogen narcosis, we let you make some calculations to test your mental awareness and examine a pressure related object and make a depth gauge comparison to demonstrate the differences between analogue and digital meters. We'll then explore the site and make a slow ascent up to safety stop depth. Providing weather conditions are good we'll make this dive at the Koh Rang Pinnacles or any other deep site in the neighbourhood.

The underwater navigation dive*
We’ll explain the principles to you we use everyday to find our way around the dive sites. This includes compass work and using a timing device, combined with natural navigation such as depth, bottom composition, contour, rock formations, corals and sunlight. You'll complete some simple exercises such as measuring distances and navigating a square pattern and a triangle.

* Mandatory dives

The other three dives are optional - you can discuss with your instructor which dives will benefit you most. Options include:

Peak performance buoyancy: In this dive we aim to get you moving through the water more efficiently, resulting in reduced air consumption (so longer dives). We'll concentrate on how much weight you're wearing and where you are positioning them, how you are controlling your breathing and ensuring your equipment is streamlined. Choosing this dive can make a big progress to your diving.

Night Dive: Something completely different and not to be missed! Armed with an underwater flashlight you'll plunge down into the darkness to explore the reef by night.

Multi level & Computer Dive: Deep diving is fun as it extends the limits of your exploration, but bottom time becomes limited if you follow a single level dive profile. If we move to a more sophisticated planning technique, using a multi level plan (and back this up by wearing a dive computer) we can vastly increase our available bottom time. This also allows us an opportunity to make another great deep dive.

Underwater Naturalist: Learn more about the aquatic realm, appreciating the relationships between different species and starting to identify some of the marine organisms that we see.

Search and Recovery: Find out how to execute underwater search patterns such as a U - search or expanding square. When you locate an object, what if it is too heavy or bulky to safely lift it using your BCD? We'll show you how to utilise a lifting device such as a lift bag, to safely recover the object.

Underwater Photography: Have a go at capturing some underwater snaps using a digital camera with underwater housing. First we'll teach you a few simple rules to improve your chances of getting the perfect shot. We'll burn the photos onto CD so you have a nice souvenir to take home. Costs 1000 baht extra.

Drift Dive: Why fight against a strong current for half a dive when you can 'go with the flow' and have the boat move and pick you up. Great fun flying effortlessly along in the current.

Dive Propulsion Vehicles: Get a dose of 'James Bond Style' under dive propulsion vehicle action! Save air, see more of the dive site and have an exhilarating time in the process.
