Why take your divemaster diving course at Impian Divers?

Divemaster training is vocational training, as well as the basis for instructor training. Doesn’t it seem logical as being Dutch or Belgian that you better take such an important training abroad at a Dutch diving school? Especially if you are going to be working as a divemaster somewhere soon, wouldn’t you like to have good knowledge in house with guiding very experienced divers around?

Hence, we take this training very seriously, and we are happy to share our vast diving knowledge with you, so that after this training you will be independently guiding divers with our own boat around one of Koh Tao’s many beautiful dive sites.

Impian Divers is known as a Dutch diving school because we employ experienced Dutch diving staff permanently.

However, with regularity also non-Dutch people come to us for dive training, so we are just as international as other dive schools on Koh Tao. In fact, we also offer diving courses in English, French, German and Thai.

Use diving equipment

Throughout divemaster training, you may use our well-maintained diving equipment. Once you know a little more about diving equipment you can buy your own.

We are happy to help and at 4 different dive stores here on Koh Tao you can purchase Mares; Aqualung; ScubaPro or X-Deep equipment at a 15% discount through Impian Divers.

Entry conditions
  • Minimum age 18 years
  • Rescue diver certification (from any diving organization)
  • Medical Trained; AED and Oxygen provider trained
  • Down payment of 10,000 THB
  • Minimum of 40 logged dives (excluding training dives)
    • In exchange for assistance in the dive shop, required number of dives can be made.
    • Valid medical certificate (Fit to Dive).

Internal divemaster training takes about 4 to 6 weeks. You may take longer, especially if you want to get some more experience navigating the dive sites, or assisting with dive training.

Cost Summary

After the divemaster diving course you will need to apply for membership in the training system of your choice in order to work as a divemaster or should you wish to advance to the diving instructor course.

These costs are almost the same for I.D.D; SSI and PADI, which are currently about 80 Euros. However, only an I.D.D membership automatically includes professional diving and liability insurance.

Membership is by calendar year. For a PADI dive master course, there is an additional cost of the training materials, which is about 7,000 Thai baht.

Frequently Asked Questions

Learning to dive is done at a diving school. It is wise to choose a diving school affiliated with a reputable organization such as the IDD, SSI, NOB, NAUI or PADI.

Know that these organizations themselves do not have diving schools, but diving schools themselves choose from one of the many training systems.

Diving is not dangerous, even in Thailand, as long as you are properly trained by a recognized diving school and you continue to follow the basic rules. There are only 3 of them:

  • Always keep breathing
  • Do not take off too fast (10 m / minute)
  • And stay with your buddy

Diving or learning to dive during your vacation is an awesome experience. However, one of the things you have to watch out for here is diver’s disease (also called caisson disease or decompression sickness). This is caused by if you stay underwater too long and/or if you ascend to the surface too quickly after a dive.

Main reason for this diver’s illness is dehydration, poor physical condition, medication use or flying too fast after your last dive. So everything is easily prevented by: eA good training, good preparation, good dive planning, staying healthy and not flying for 24 hours after your last dive.

Diving for kids is a dream, but can become extra fun if you can dive together with your kids or as your whole family.

Impian Divers Tao is happy to help make that dream come true. For families with young children as well as families with teenagers, we think about customized solutions.

How about a diving course tailored exclusively to your family? Learn together, dive together and get your diving license together.

When to Thailand to dive is a common question. Logical when you fly 11,000 km with.

Thailand has a tropical climate and it is about 26 -30 degrees all year round. The best travel time is from December through June. Then there is little rain and lots of sunshine, exactly what you want when you are at the beach!

During the months of July and August there is a bit more wind and normally November is the rainy month here on Koh Tao.

Koh Tao is fine to visit all year round, but sometimes there is a chance of a daily tropical shower. The advantage of this is that everything is in bloom nicely and it is a little less hot!

However, for a diving course, it doesn’t matter. Wet we will get anyway!
There are dive sites all around Koh Tao, so we always find a sheltered spot for the shallow water exercises.

Sometimes visibility is a little less, but this can also occur during the dry season.

This is because the Gulf of Thailand is relatively shallow, and because of the heat, algae grow in abundance . A little wind (often around the turn of the moon) and visibility will be a little less for a while.

Please email us about what the weather is like. We ourselves do not like nice weather talk and we will give you an honest answer. However, as in the Netherlands: nothing remains as unpredictable as the weather.

We check the wind and rain daily on this website
