Samran Nets

Samran NetsSAMRAN PINNACLE, o como el ser humano ha devastado uno de los pináculos más increíbles del golfo de Thailandia.

El pasado 29 de Abril, Davy Jones Locker tuvo el placer de disfrutar de una de las inmersiones más desconocidas y pocos visitadas. Samran Pinnacle, al  sur de Sail Rock, se compone de 3 pináculos a diferentes profundidades, estando la máxima a unos 30m.

Fue un día soleado, con un mar calmado y con una visibilidad +30m. Todo el mundo estaba muy emocionado por visitar ese famoso pináculo que tantas alegrías habia dado en el pasado. De hecho era un sitio muy visitado por tiburones ballena y otros mamíferos como delfines.

Al ser un sitio muy poco visitado por buceadores, puesto que esta alejado de las islas principales Koh Tao o Koh Pangan, sabíamos que existía la posibilidad de encontrar algunas redes abandonadas, pero lo que nos encontramos allí fue mucho más que algunas. Fue un paisaje totalmente devastado por redes y cajas de pesca, algunos peces intentaban escaparse, algunos cangrejos pedían ayuda para soltarse, y como no, todos los buceadores de Davy Jones Locker contribuyeron a salvar a todas las especies que pudieron y también reflotaron algunas de las redes. Obviamente menos de las deseadas, pues la longitud y el peso de las redes superaba con creces lo permitido para realizar un ascenso seguro.

Tan triste fue la escena, que este mes quiero compartir con vosotros los efectos de las redes en los fondos marino y el gran volumen de especies afectadas.

Looking after your ears

By , 29 April, 2016, No Comment

looking after your earsInstructor Matt has written a new article for the DJL blog explaining how to take care of your ears and avoid the problems some people may experience during a dive. Your ears are particulary sensitive when diving due to various pressures which can lead to pain and possible injury. The tips below will help you avoid any of the potential issues that can arise.

“How to avoid ear problems whilst diving:

We all know as divers our ears can be our achilles heel, an ear infection of a perforated ear can have us out of the water for days if not weeks. Luckily for us there are many ways that can help us prevent these problems from arising.

• Clean your ears after the dive- you can use a couple of different methods for cleaning your ear post dive: firstly you can use either a commercial product designed to remove water from the ear canal, Secondly (and more cheaply) you can use a mixture of half white vinegar and half rubbing alcohol after a diving excursion to gently clean and dry the ear canal. This can also help to prevent swimmer’s ear.

• Avoid boat fumes- Breathe fresh, clean air before descending into the water. Since the eustachian tube connects the eardrum to the throat, and ultimately the respiratory system, avoiding irritants such as boat fumes and cigarette smoke will help divers avoid inflammation and pain.

• Stay hydrated- Drink lots of water to thin mucus so that it doesn’t clump and block the eustachian tube.

• Avoid dairy products- It is recommended to avoid dairy products for two days before a dive as it can contribute to thick mucus.

• Avoid diving with congestions- dive with congestion or a cold when there is already a buildup of fluid in the throat and eardrums. Congestion causes a shrinking in the tubes, which makes it harder to force in air and equalize pressure.

• Sinus rinses- Use a nasal rinse or oral decongestant to help thin the mucosal lining and flush out irritants that can block nasal passages. Check with your physician before taking any medication, even over the counter, before using the medication while diving

As you can see from these helpful tips, ear care prevention is better than cure. Take care of your ears guys and they will take care of you. Happy Diving!”

Unicorn Wreck diving with DJL Tech crew

Unicorn Wreck diving with DJL Tech crewDavy Jones Locker instructor Matt is also a certified tech diver and has written a new article for the DJL Blog. The tech crew visited the Unicorn Wreck near Koh Tao for some experience diving and also to complete the training of students taking tech courses

 

 

Unicorn Wreck diving with DJL Tech crew“The DJL Tech crew have been diving the Unicorn Wreck which is located around 4 nautical miles North of Koh Tao in around 48m of water. Preparation for the the dives began the day before with the checking of equipment, mixing and analysing gasses, and dive planning. It was then a nice early start to move the equipment down to the beach, on to the longtail, which would then take the team to the bigger tech boat.

Wreck Spec advice

By , 10 April, 2016, No Comment

wreck spec adviceDavy Jones Locker instructor Dani recently took one of our Divemaster candidates Kieran through his Wreck spec,  following that she has written a new article for the DJL Blog containing some great wreck spec advice. Wreck exploration and penetration is one of the most exciting aspects of diving but does have some inherent risks and dangers that divers need to be aware of.

 

“Danis Wreck spec tips :

For many divers the greatest thrill is exploring ship wrecks. But, as you progressed through your open water training, you were no doubt constantly reminded about the dangers of entering wreckage or any overhead environment. The dangers are real and valid whether you are a relative new comer to diving or a seasoned dive professional with many thousands of dives.

CCR Cave Diving Song Hong

By , 30 March, 2016, No Comment

CCR Cave Diving Song HongBeing an open circuit cave diver and enjoying the challenge of the deep caves of Thailand I have for a long time wondered about the benefits of closed circuit rebreather technology in relation to caves. As CCR divers will tell you the units work best in a classic diving profile (max depth work shallower) and when a diving colleague Bruce Konefe took me on a course, ANDI CCR cave, I was intrigued to learn about the gas management rules for cave profiles as caves tend to follow their own profile without regard for the divers.

The cave where we were to complete our training, Song Hong, is a huge sink hole slap bang in the middle of Thailand. Song Hong is well known with local cave divers and stands out for its’ enormous size and depth with exceptionally clear water below the hydrogen sulphide layer. Part of the sink hole which allows for direct access to the surface is used by technical divers wishing to complete wishing to complete deep trimix diver training, avoiding the problems associated with currents and elevating respiration in the sea.

ccr cave diving song hongAs any rebreather diver will tell you you, rebreathers, due to the design do not lend themselves to achieving good trim, a skill that is essential for cave diving. A lot of time was spent moving weights and adjusting the height of the wing to counter the lift at the shoulders caused by the counter lung. The rebreathers I had with me, Evolution and Inspiration, due to the box they are protected by make it hard to move weights and tanks, to assist in this and I found it easier to remove the can and head and put them in a customized box. This has helped a lot and now it isn’t so much effort to maintain a horizontal position acceptable for cave diving.

CCR diving song hongThankfully the gas management rules were a lot easier to master although I was surprised to see many applications of this. It depends on the amount of divers in a team and the amount of confidence in the individual team members, running from the bare minimum, carried around team members with a variation calculated at the largest RMV of this with a third reserve on top again. This is shared around the team to the old third in third out thirds developed by Sheck Exley with each team member carrying their own reserve. It can be quite unsettling when at depth and on the way in to a cave if you start to have doubts about your buddy’s ability to keep his shit together when the said shit hits the fan and you’re relying on your buddy to carry part of the emergency gas you need to get to the surface! At this point you begin to choose your buddies more carefully bearing in mind it’s the team gas rule that that has helped cave divers push back the curtain and explore deeper and longer cave systems.

CCR cave diving song hongOverall though CCRs greatly enhance the divers ability to explore caves and with careful adherence to the gas rules (whichever one you adopt) and choosing your your buddies with as much attention to detail there is no doubt CCRs take cave diving to another level. Happily, I had good diving buddies and the shared enjoyment of achieving a goal of completing the 60 metre circuit added to the pleasure.
