I want to learn how to dive. Where do I start?

If you want to learn how to dive, we would suggest looking at our Open Water Course page for all the details. It is the basic diving course and the best way to discover what the underwater world is like.

If you’re unsure of whether the Open Water diving course is for you, check out our   discover scuba diving program where you would get a taste of what diving is about. It is a day session at the pool where you’ll learn the very basics of diving and get to experience what breathing underwater is like. Click here to find out more.

What is the minimum age to become a diver?

To take the SSI Open Water diving course, the minimum age is 10. Children will receive a junior Open Water certification which can be upgraded when they turn 15.

What does the SSI Open Water Diving License allow me to do?

After getting certified, the SSI Open Water Diver certification allows you to dive up to 18m with a buddy.

How long is the course?

All our dive courses are designed to fit the schedules of working professionals so everything happens after regular working hours. The SSI Open Water diving course involves 1 theory session (Tuesdays, 7-10pm), 1 pool session (Sundays, 9am – 4pm) and a weekend trip (Friday evening, 6.30pm – Sunday night, 9pm). Timings can vary depending on both sea and land travel times.

Do I need to buy any equipment for the course?

No, you do not have to buy any equipment for your dive course however, students are required to rent soft gear (mask and fins) for the course. We have exclusive equipment bundles for our students here as we believe that owning your own equipment would make the dive course safer and more enjoyable for you.

Do I need to be a good swimmer to learn how to dive?

Part of the SSI Open Water requirements is that students be able to swim a distance of 200m or snorkel with mask and fins for 300m and do a 10 minute tread/float.

You do not have to be a strong swimmer to learn how to dive but being able to meet  the requirements would ensure that you will be safe during your open sea dives.

How deep will I be going?

As an SSI Open Water Diver, you are qualified to dive up till 18m. However, during your course, most dives will be around 6-12m.

How often are Open Water Trips organised?

Open Water dive trips are organised every week to Tioman, Bintan as well as Phuket.

Find out more about each destination here.

Does my SSI Open Water Dive card expire?

Your dive certification does not expire however if you haven’t been diving for more than 6-8 months, we would recommend going for a refresher in the pool. Getting familiarised with not only the skills underwater but also dive safety concepts will make your subsequent dives safer and more comfortable.  Find out more about our refresher course here.
