DMT Event

By , 25 November, 2014, No Comment

At DJL we are lucky to have a very large group of DMT’s (PADI Divemasters) at any one time throughout the year, at the moment we have approximately 20. These guys put in so much hard work and are such a huge part of what makes DJL the amazing place that it is!

So to show these guys how much we appreciate everything they give to this school, a DMT Event was organized culminating in a pool party and BBQ! This event was a mix of having fun as well as improving dive skills and dive knowledge! We were lucky enough to have Koh Tao Pro Video film the entire 2 day event and make an amazing film for us all! We had the guys go to Buoyancy World for an underwater treasure hunt, where they were graded on a variation of different tasks, including tying knots and having to show their knowledge of diving hand signals! We also had a quiz where our DMT’s showed off their dive knowledge, a ‘James Bond’ event, a beach clean up and other tasks!

HTMS Sattakut

By , 26 September, 2014, No Comment

Hey all,


today I’m going to be talking about one of the great wrecks we can dive to on this island, the HTMS Sattakut. The Sattakut was laid down at Commercial Ironworks in Portland Oregon. She was launched on February 27th, 1944 and commissioned into the US Navy as a Landing Craft Infantry large. After her long service she was commissioned into the Thai Navy as the HTMS Sattakut in 1946, and was sunk in Koh Tao on the 18th of June 2011 and to this day she is one of the most popular sites to dive especially for a PADI advanced open water course.

She lies approximately 40m south of Hin Peewee with her bow facing Northwest, Sitting upright. The top of the wreck is around 20m and and since she lies on a slope the bottom is at about 32m. When she was sank as a part of an artificial reef project in 2011 she landed on her starboard side in a different location to where she is now, it was only after a few months that her position was corrected and she was put back upright that more and more people started to dive on her.

Shop opps course and DJL

By , 23 September, 2014, No Comment

DJL offer a wide range of scuba and tech diving courses, PADI open water up to instructor and everything else in between, but they also offer a range of courses called shop opps, a 4 day course which is learning how to fix and maintain scuba equipment, such as BCDs and regulators, compressor maintenance and gas blending. Being out of the water with an ear infection, I decided to take the course as I wanted to expand my knowledge of scuba equipment as well have something new to add to my diving CV.


First thing we did was compressor maintenance. This proved to be dirty work as we were learning to change the oil the tank compressor. At first I struggled a bit with the using the tools but Ed the instructor was very helpful and patient and I soon got the hang of it. We also learned how to fill the tanks and change the filter, a very handy skill for anyone looking to get a job on a dive boat.


Next we learned how to service regulators. This again is a very usefully skill to have as getting your own regulators serviced can be expensive and learning how to do it your self can save you money. We also learned how to identify and fix any problems a regulator may be having, whether it be a leaking SPGs to a wet breathing second stages. We also looked at fixing leaking tanks and how to patch up BCDs that have holes in them, two more very usefully skills to have. There is also the option of taking gas blending course, which teaches you how to mix gases for nitrox and tech diving, which I will take later in the year.


I would definitely recommend the shop opps course to anyone, especially professional divers. Skills such as the ones you learn over the 4 days are incredibly valuable and many dive companies will look for it on a CV.

New way diving rescue diver

By , 2 September, 2014, No Comment

While I teach a lot of Open Water courses my favorite course to teach is the PADI Rescue Diver. Here at Davy Jones Locker we typically spread over 3 days with theory, confined water training followed by a session in the sea. The course is often taught in conjunction with the Emergency First Responder (primary and secondary assistance course). It runs through possible scenarios of what may go wrong before and during a dive and will teach you how to recognise them and respond to them safely. The fun part for me is being able to relate to students real stories of problems that have occurred but exaggerating them to test how the rescue students cope in different situations and getting them to start thinking safely by going over what we did and how we would do it differently next time so that we all improve our diving skills, and my teaching skills as there is always something I can do better.

It will be highly unlikely that you will ever have to use these rescue skills, but wether you are honing your dive skills as a recreational diver or taking it as a step towards the PADI Divemaster programme it will teach you to be a more safer and aware diver whilst giving you the training and confidence to deal with an emergency.

Unicorn Wreck

By , 25 July, 2014, No Comment


It has always been rumored that at the time of it’s sinking in 1989 the 60 meter long Unicorn was sunk on purpose as an insurance scam. Local Koh Tao inhabitants said that the ship just pulled up off shore, around a mile north of Koh Tao and over the next couple of hours slowly sank after an explosion on the vessel. No-one was hurt in the sinking. An Insurance fraud was immediately suspected, insurance investigators were sent to investigate the cause of the sinking and to confirm the cargo which was listed as expensive Tuna Fish. Divers descended to examine the wreck, and discovered that the holds contained nothing but low-grade animal Feed (Dog-Food) un-fit for human consumption, NOT expensive Tuna fish as listed on the manifest. hence the nickname it later aquired – the “dog food” wreck.


Lying around 12km north and 20-30mins off Koh Tao and in 50 meters of water the vessel lies, mostly intact, on it’s port side at an angle with the top of the bow at 38meters, and the keel of the bow area several meters above the seabed, allowing divers to swim under this area of the hull. Fishing nets have been removed from the wreck allowing some moderate penetration. Big schools of jacks, batfish and barracuda patrol the area directly above the wreck with a pair of large groupers residing inside the wreck. Here at DJL we often dive the Unicorn as part of our Technical diving program, especially the Tech 45 course. Due to the depth and location it is always quiet and diver free. I dived the Unicorn for the first time in march last year, as the visibility was very good the wreck appeared to have an eerie greenish around the outline of the wreck (maybe just narcosis) and was enthralled by the always curious bat fish.
