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

To learn how to dive, you must first begin with the basics. And the basic diving course is the Open Water Course which we offer and you can check on our page for details.

Or you can try out our Discover Scuba Diving Program to have a feel of what diving is like. You will also learn the basics of diving and experience breathing underwater at a convenience of a swimming pool where it is done during the day. Click here.for more details.

What is the minimum age to become a diver?

The minimum age to take the SSI Open Water diving course is 10 years old where the child can earn his/her junior Open Water certification and upgrade it when he/she turns 15 years old.

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

Once you finish the course and receive the certification, the SSI Open Water Diving License entitles you to dive up to 18 metres with a buddy.

How long is the course?

The time for each course varies depending on sea or land travel. Dive courses are held after office hours as they are catered to fit the schedules of working professionals. The SSI Open Water Diving course includes 1 theory session (Tuesdays at 7-10pm), 1 pool session (Sundays at 9am-4pm) and a weekend trip (Friday evening at 6:30pm – Sunday night 9pm).

Do I need to buy any equipment for the course?

There is no need to buy equipment for your dive course though rental of soft gear (mask and fins) is required for the course. We believe owning your own equipment would make the dive safer and more enjoyable that is why we provide students with exclusive equipment bundles.

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

You do not have to be a strong swimmer to learn how to dive but part of the SSI Open Water requirements is for students to be able swim a distance of 200 metres or snorkel with mask and fins for 300 metres and do a 10 minute tread/float. This way, you will be safe and secure on your open sea dives.

How deep will I be going?

During your course, most dives will be around 6 to 12 metres however, once you finish your course and earn your license as an SSI Open Diver, you are then qualified to dive up to 18 metres.

How often are Open Water Trips organised?

Open Water dive trips are organized every week and some destinations are Tioman, Bintan and Phuket. Find out more about our destinations here.

Does my SSI Open Water Dive card expire?

No, your certification does not expire though we would recommend taking a refresher in the pool if you had a 6-8 months break from diving to boost your skills underwater with dive safety concepts that will make your next dives safe and sound. Find out more about our refresher course here.
