About Big Blue Pro Located on Sairee Beach - Koh Tao


Simon Garrity

In addition to offering Instructor Training, Simon is also an SSI Instructor Certifier and an SSI International Training Director. This means that he examines ITC candidates in the IE, and trains new Instructor Trainers. He is currently the only one holding the rating of ITD in SEA. So why not be trained by the guy who trains the trainers to train? Originally from Liverpool in England, Simon has over 16 years In the industry, mostly on Koh Tao with Big Blue Diving.




Iain GoodfellowIain Goodfellow

Iain has been working as an educator / trainer for over 18 years having spent the last 7 years promoting professional training at Big Blue.  He has certified more people through the SSI system than anyone else globally and is a member of SSI's elite 'Platinum Pro 5000' club.

Iain is the success story of Big Blue Diving appointed as a DCSI mentor after a meteoric rise through the instructor ranks. Originally Scottish, Iain is so good at his job we’ve reclaimed him and he is now, like Andy Murray, proud to be British. If he ever let’s his incredible performance slip, even for a moment, he’ll be demoted to being a Scotchman again in a highland second though, don’t you worry! Fluent in Japanese and a former troubled teen care worker, Iain is quite possibly Koh Tao’s most eligible bachelor.

 Ant Silwood


Despite the fact Ant is Welsh we still went ahead & employed him! Must be something about his likeable personality, charm, good looks & our necessity to have someone to pick on! Ant is a PADI & SSI Instructor having been professionally trained by some of the leading Scuba Diving Instructors in the business. I wonder who they were. He is also one of our Divemaster Trainers & having worked as a DM with us for a couple of years already really knows his stuff. Originally a Computer software salesman with an alleged talent at being able to fix computer problems, Ant has on numerous occasions proven this fact to be a complete joke & can't even spell PC let alone fix one! However he is very relaxed, reliable & great eye candy for the ladies!



G MaguireGermaine ‘G’ Maguire

Meaning ‘relevant’ or ‘pertinent to’, Germaine is Koh Tao for so many of us. Widely loved and one of the longest serving instructors around, Irish G has finally returned to us after an ill-advised Whale Shark hunting expedition to Utila in Honduras. The entire island celebrated not so long ago when our G finally, after 12 years of teaching and over 5000 dives, finally saw her first Whale Shark here on good old Koh Tao. Since then she has become something of a big fish magnet with 4 big blue fish with white spots on them circling her and her students at Chumphon the other day! The sixth member of our DCSI professional Training Team, G is experienced, funny, hotter than Tosh in his lime green speedos, and she owns her own bar, restaurant and nightclub. Form an orderly line and prepare to be vetted!

 Phil Smithfishlad

A horticulturist by trade, Phil ran his own landscaping business in the Lake District area of the UK! Gave it all up to go traveling the world and ended up here! Oddly enough was nicknamed 'Fishlad' by his mates at school way before he took up Scuba Diving as a career! They reckoned with a nose that big he looked like a sea creature. Should have called him Elephant Seal Phil!  Phil started work here at Big Blue as a Divemaster & became a PADI and SSI Instructor as well as one of our Sidemount Instructors. He is now the newest member of our mentor team, and a great addition. He is very laid back & patient is Phil. Excellent qualities to have as a Scuba Diving Instructor and as an elephant sea, with hobbit feet.


Nick Bufton

nick B

Separated at birth from Sid the Sloth, Nick is one of our fully qualified SSI and PADI Instructors. Trained by another rival dive shop here in Koh Tao and even worked there for some time as a Dive master then an Instructor then as an Instructor training Divemasters! This is exactly what he’s doing now. He has a great track record with his Open Water students who continue with their Advanced Course and is also a very accomplished swimmer and holding the record for our 'Swim for Sharks' charity event we host every year, swimming 3.5 kilometres around the island of Nang Yuan in just 55 minutes to raise money for Shark conservation. Not a bad time for a slow moving mammal that lives in trees!
