Dutch-speaking PADI dive school

Never dived before? This is where you start.

Most people who come to us have never dived. After three days you hold a certification that is valid worldwide. Rather try it first? Our one-day Discover Scuba Diving is made for that.

  • No experience needed

    The PADI Open Water course is made for people who, on day one, have never dived before. You start in shallow water and build up calmly.

  • Dutch or English

    Theory, safety briefings and the questions you would rather ask in your own language: our instructors speak Dutch, and we teach in English too.

  • Small groups, on every course

    That way your instructor notices when something is hard for you. And there is time for your questions, above and below the water.

Photos from our own album. Around Koh Tao you see tropical reef fish, rays and barracuda. Turtles are seen regularly, whale sharks sometimes, mostly around Sail Rock, never guaranteed.

A day with us

A briefing at the school, then onto the boat

You start with a briefing at the dive school: what you will do, what you will see and how we keep it safe. Then the boat takes you to the dive site. We dive only with modern equipment that is cleaned and checked after every dive.

What our students wrote

What students wrote about us after their course or fun dive.

Under Sander's guidance I got my Open Water here. I can recommend it to everyone! Everything is explained clearly and calmly, so you know exactly what to expect. All in all a really nice atmosphere and a great 3 days! Thanks!

Mats van den BergPADI Open Water

Did the PADI Open Water and Advanced at Below Zero Divers with Anouk as instructor, plus a full day of fun diving. Really fun dives and loads of cool things seen underwater. The lessons were really easy to follow, clear instruction and a really friendly vibe every day. On top of that we got beautiful photos! Genuine people who really want to teach you something and are always up for a drink and a chat after diving. Would absolutely recommend it. 10/10!
