Tec 45

By , 26 March, 2015, No Comment

I completed my training of the Padi Tec 45. It was a very informative course and a lot of fun. Firstly you go into the pool to complete some confined training, mastering buoyancy and practising skills needed when diving deep. S-drill, valve drills and all the skills we complete are all done neutrally buoyant. Then we had to plan our dives taking into consideration all of your decompression stops. We planned to dive on the Unicorn wreck, just north of Mango Bay on the north side of Koh Tao. Our dive was to 45 metres and we spent 25 mins trying to navigate our way around the wreck.

The visibility was not great the day we dived but we still managed to have a great day and completed our decompression stops successfully. It took nearly 35 mins to get back to the surface. We also switched gases at 21m to Nitrox 50%, to make our dive more conservative. I highly recommend contacting DJL tech department to do some technical training with Instructor David Polley. I had a lot of fun on this course and it will enhance your diving ability and understanding of decompression theory.

Wreck Specialty

By , 21 December, 2014, No Comment

As I’m sure everyone who has done a Wreck Adventure dive will know there is nothing quite like the feeling you get when you first see it emerge from the depths.There is a eeriness to exploring a wreck underwater that is completely unique, and as you float above it looking down there is a sense of grandeur and if I’m honest a slight feeling of insignificance. Saying all this however a wreck adventure dive pales in comparison to completely your wreck specialty. As soon as I was told that during the wreck adventure we could not go inside it all I wanted to do from that moment was go inside it. A feeling only increased when we got down onto the wreck and could glimpse inside the entrances and port holes. As soon as I hit land after the dive I signed up for my wreck specialty.

A few days later I was starting my wreck spec and it did not disappoint. Being inside a wreck gives a whole new range of aspects to diving that I had not yet encountered and as your level of skill needs to be that much higher for wreck penetration the skills you learn throughout the dive take you up that much higher in skill level. I don’t think my buoyancy control and trim in the water has ever improved so much in such a short period of time. Being enclosed in a corridor 30metres down in the bows of a WW2 wreck will do that to you.

The staff at Davy Jones Locker Diving are also very knowledgeable when it comes to the wrecks around Koh Tao, and knowing the history of a wreck gives a whole new level of interest to the dives. I cannot recommend a wreck specialty highly enough, if like me that first wreck dive just left you wanting more it’s just going to be an inevitable conclusion.

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.
