First, we will discuss with you navigation techniques and planning deep dives. Then, spread over 2 days, you will make 5 beautiful dives with your instructor. All with the intention of making you an advanced diver!

Objective advanced open water course

Think of this as only increasing your confidence underwater, so you will get even more enjoyment out of diving. After completing this course, you will be allowed to dive deeper, be able to navigate on your own and also be able to optimize your buoyancy.

We offer all diving courses of the I.D.D; SSI; and the PADI training system. You may of course choose for yourself, but our advice is the Dutch I.D.D. training system because of thorough insurance.

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
