Discovery Divers - How it all works

Discovery is now running four purpose built speedboats including our brand new “Discovery” boat to get you to all of the dive sites in the Gulf of Thailand fast and comfortable. We have our 3-engine 750 HP 47′ “Jagger”, “Priabdaw” and “Discovery” boats plus our 2-engine 450 HP “Stoli” boat. With these four boats we can reach Koh Tao in under 90 minutes and under 60 minutes to Sail Rock. This leaves more time for diving and we can get back to Koh Samui in time for you to enjoy other activities for the rest of the day.

All of our boats are equipped with marine toilets, emergency oxygen, first aid kits, navigation units, and life jackets. Our captains are also the most experienced on the island and our food is hands down the best.

Certified Divers

We know that while you are on vacation your time is precious and you don’t want to waste it washing your equipment and humping it around between your resort and our Dive Centre. As a full service Dive Centre, we take care of YOU and YOUR EQUIPMENT. We will dismantle your equipment, clean it and store it for you after each dive.

You simply have to just step off the boat. The emphasis is diving in smaller guided groups (maximum 4:1) tailored to suit abilities and interests with highly experienced, professional staff to assist, enlighten, and entertain!

Rental Dive Equipment

We pride ourselves on our state of the art rental dive equipment. All rental equipment is renewed annually and consists of the latest regulators including a 2-gauge console. All of our gear is washed daily after use and dried in our on-site equipment room.

We have a comprehensive range of Men’s, Women’s and Children’s 3mm shorty wetsuits as well as a wide variety of fins, masks, and snorkels to fit virtually everybody. In addition, we also hire digital underwater cameras, console and wrist dive computers.
