ISC Megalodon Rebreather at DJL

By djl_team, 8 August, 2010, No Comment

Davy Jones Locker is now offering Closed Circuit Rebreather “Try Dives” using the high tech Innerspace Systems Corporation “MEGALODON” CCR.

The ISC Megalodon is a Variable Volume, Mixed Gas, Constant PO2, Closed Circuit Rebreather used by Technical and Military divers worldwide.

In short it means that you are diving with the most technically advanced diving system on the planet..

A simple explanation is; Closed Circuit Rebreather’s or CCR’S are underwater breathing systems designed to recycle the exhaled gas back into a breathing loop where the CO2 is removed and Oxygen is added to maintain a constant PO2.

A CCR is basically a Nitrox blender on your back, giving you the perfect blend of Nitrox at any given depth.

CCR’s have the added benefit of diving silent. Without bubbles you don’t scare the fish… giving you the most out of your underwater experience…

Discover Rebreather Diving Includes: 1 Confined and 1 Open Water dive..
Only: 4000 THB
*Try Dives are available to anyone with an Advanced Open Water Certification or higher.
*Open Water divers must have minimum 20 dives to qualify.

New BSAC Mixed Gas Courses at DJL

By djl_team, 7 August, 2010, No Comment

Davy Jones Locker Diving is to be the first dive school in Thailand to adopt the new BSAC Sports Mixed Gas, Advanced Mixed Gas and Explorer Mixed Gas courses.

These courses are designed to incorporate helium into the breathing gas in progressive amounts and at progressive depths.

The sports mixed gas diver course will allow the diver to use a minimum of 20% O2 and a maximum of 30% helium content, decreasing the effectiveness of narcosis and CO2 retention normally encountered on air dives to 50 metres.

Tim Lawrence at Davy Jones Locker commented that the new BSAC materials have up to date information on decompression techniques used when diving helium profiles. The helium content on the first course is controlled to avoid problems with isobaric counter diffusion and the depth is limited to 50m to avoid the normal problems encountered in air diving.

At present we intend to give our customers the option after completing the BSAC advanced Nitrox course of completing the existing extended range course using air to 50m or switching to the sports mixed gas diver course to 50m. We believe that using tri mix will always make diving to more than 40m less problematic than diving with air due to the cost of helium and the financial constraints placed on diving professionals which make up the majority of our courses. There is a high chance that our customers will dive to 50m on air, consequently it’s better to teach these divers the dangers of narcosis and CO2 retention to prepare them for this eventuality. We do however fully embrace the BSAC philosophy using mild helium blends to enhance the safety of this type of diving. We feel that by giving our students the opportunity to chose between these two courses is a more realistic approach in our market place at present and intend on giving them the discipline they require to progress into tri mix and become better tri mix divers.

Davy Jones Locker Pricing details for these new BSAC courses are as follows:

Sports Mixed Gas Diver – 25,000 baht, plus gas costs (diver must have complete advanced Nitrox course)

Explorer Mixed Gas Diver – 20,000 baht, plus gas costs

Advanced Mixed Gas Diver – 80m depth required, price depends on dive sites chosen POA

FCD Update………….

By frankie, 27 July, 2010, No Comment

Hello everyone, just to update Tim and Frankies progress with BSAC’s First Class Diver. The exam which took place in May was run over two days and along with the two DJL candidates we also had Frank from Divepoint. Apart from the expedition plan which had to be submitted at the start of the exam we all had to plan either a reef survey, a wreck survey or a lift. So there was plenty to keep us occupied. Starting with the lift which Frank was in charge for we were able to manouver a large block for the bottom up to the surface and then onto the boat, which all went swimmingly. Tim’s wreck survey also proved to be very achievable and did not produce any unexpexted problems, which also was the case for Frankie’s lead at Hin Wong Bay.

The following day however things were about to get a little more testing. Upon arriving at 9 we were told we were going to have to biuld and place two gates for an underwater orienteering course. Definitely something new to get our collective heads around. While Frank was in charge of the design, Frankie and Tim were there to help create and place the gates in the water. As the dimensions had to be 2m by 3m and had to maintain an exact depth of 10m to 13m this was requiring a lot of thought and team work. However Frank came up with a siutable system and after a couple of hours we seemed about ready to get the structure under the water. This was unfortunately where the team came up short, as when placed in the water the lines we were using became entangled and we were unable to properly deploy the two gates. That said a lot had been achieved and more importantly a lot had been learnt.

A couple of days later we were all debriefed individually and I’m very glad to say that all three candidates passed!!. So with one part out of the way we look forward to the theory exam in coming months. Good Luck to everyone and we hope we will see them celebrating a new achievement soon.

Divers go 1st Class

By frankie, 22 March, 2010, No Comment

Two Divers from the SEA Explorers club, Tim Lawerence and Francis Leigh will be attempting to complete their BSAC First Class Diver qualification over the next three months. As all you BSAC divers will know this is the highest ticket anyone can attain from BSAC and will require many hours of hard work and study over the coming weeks. So for now its time to stick our heads in the books and get practising our search patterns and hopefully by the end of May we will be celebrating the clubs first two members achieving its highest award. Stay tuned for updates on their progress in the coming days.

Reef Cleanup and Whale Shark for Explorers Club

By frankie, 1 March, 2010, No Comment

Lately the SE Asia Explorers club has been looking at ways of getting more involved in the ecological side of diving. As a result a reef cleanup was planned on the local house reef, Sairee Beach. As a way of encouraging more people from outside the club to join we organised a first dive at Chumphon Pinnacles before returning to Sairee to do the reef cleanup. Happily for us lots of people were more than happy to get their fingers dirty and get involved.

So after a couple of days of drumming up divers and preparing the site, we were all ready to go. Heading out bright and early on the morning boat, the sun was shining and a gentle hum of chatter and preparation on what was a very busy boat. Arriving at the site, conditions as often are at this time of the year, were great. Little current and good visibility. Descending to the top of the pinnacle we were greeted by a big school of yellowtail barracudas intermingling with some big trevallies. You might all remember from a previous post when cleaning nets from the pinnacle we were lucky enough to see two whale sharks and once again Chumphon didn’t disappoint.

The normal size for these giant pelagics in this area is usually around 3m, so we were gratefully surprised to see larger specimen of nearly 5m. For a lot of the divers on the boat this was their first sighting and being in a playful frame of mind, they were able to spend nearly the entire dive with this graceful creature. A special moment for anyone present.

Back on the boat we began the ride of about 30 minutes back towards Koh Tao. The team having done some reconnaisance earlier in the week had marked a number of areas on the reef that needed particular attention.
