Open Water Course

An Open Water course is accessible for young and old, and upon completion provides an unlimited, worldwide valid diving certificate.

Scuba diving is simply watching fish underwater. It is not difficult at all and fun to get your first diving certificate.

You dive with your legs but keep your wits about you and that is why we at Impian Divers pay a lot of attention to your awareness during diving.
On-line study possible!

Koh Tao

Diving on Koh Tao has the advantages of the island being super cozy & safe, with plenty of dive sites ideal for the beginner and advanced diver.

In addition, it remains one of the cheapest diving destinations in South East Asia.


Our courses are adapted to individual needs, as sometimes it takes you some more time to feel more comfortable.

In this case, an extra afternoon session in shallow water will be scheduled. This gives you more confidence and fun during the course. We have plenty of time.

At Impian Divers the open water diving course lasts 3 – 3.5 days and why not immediately continue with the advanced open water course?

Only 2 extra days and therefore very easy to combine with your holiday schedule.

Course Content

After the administrative part and accepting the course conditions, the lesson starts with a good explanationof the dive theory and reasons why and which exercises you will do later that afternoon in shallow water.

After lunch break we bring you with our own boat to a beautiful dive site for the 1st exercises in shallow water.

You will start at knee depth, so you can easily just stand up if necessary. Goals is to stay under water and control your breathing.

Once relaxed we practise some basic skills before slowly go a bit deeper.

In water we always teach in small groups of maximum 4 divers per dive instructor.

The 4 dives of the open water course are given as much as possible at different locations, if the weather conditions allow this.

This to gain more experience and to see more of the island.

The open water course has 4 links between tests and a final exam. All multiple-choice questions about everything you did during the course.

1 on 1 instruction is possible, but please reserve in time and is subject to availability of dive staff during the high season (July-Aug and Dec-Jan)


This is absolutely no problem to complete the tests and exams. Report it and we will simply go through everything verbally.

Scuba Diver

If you cannot complete the last diving day for personal reasons, you can still earn a diving certificate.

All you have left to do is take the final exam.

We call this certificate Ocean Explorer or Scuba Diver, it is also valid worldwide and unlimited up to a maximum depth of 12 meters.

Scuba Diver / Ocean Explorers must always dive under the supervision of a divemaster or instructor.

Junior Open Water

Junior (10-14 years) open water course must complete the same training requirements as for adults

So independently performing the same in-water exercises and the same theory exam, again giving the correct answers .

Teaching Youngsters

Questions from the exam can be sometimes even for adults difficult to understand.

By putting the questions in different wording, we guide juniors in this way with their tests and the final exam.

We also let juniors make every training dive on a different dive site, as far as the weather conditions allow.
