Deep Diving courses, explore the ocean with DJL!

Matt is an Instructor for Davy Jones Locker and has written an article about deep diving for the DJL blog. Matt is also an active Tech Diver with considerable understanding and experience. He explains some of the benefits of diving at depth and also weighs up the risks involved and how to counter them.

“So guys, you’ve done your 18m dive and now are starting to think about going deeper? there are many steps you can take now to get your 30mtrs, 40mtrs or even DEEPER certifications!

World records

Many people ask me ‘what is the deepest you can go in diving’? Now, this question is very general. The deepest claim for an Open Circuit SCUBA DIVE is 330m . This occurred just a few weeks after Nuno Gomes set the new deep diving record of 318.25 meters (at the moment 318,25 is still the Official Guiness World Record). However, diver Pascal Bernabeis makes a claim of diving to 330 meters on open circuit scuba in the Mediterranean Sea.

How deep is deep diving?

Many people differ on their opinion of what makes a dive a deep dive.  PADI class  anything deeper than 18m in recreational diving as a deep dive. You can dive to a depth of 30mtrs during your advanced open Water course and log this as your deep dive. Others believe that below 30mtrs is where nitrogen narcosis affects you more so would consider this a deep dive. In PADI recreational diving 40mtrs is the maximum depth you can go to.

Deep Diver speciality

You can take the Deep spec following your open water course. It involves 4 deep dives where you learn many different things involved with deeper diving. These include colour changes with depth, pressure changes with depths and the affect nitrogen narcosis has on your body and reactions. Many students who take this course really enjoy the ‘egg trick’. This involves cracking a raw egg at depth to see the effect water pressure has on the egg!

Technical Deep Diving

In technical diving, a depth below about 60 metres (200 ft) where hypoxic breathing gas becomes necessary to avoid oxygen toxicity may be what divers consider to be a “deep dive”. This is more advanced diving, but again, is definitely something you can achieve by completing the relevant courses.
I recently went exploring with DJL to find a new wreck at 60mtrs, which I can tell you, is definitely an exciting opportunity.

Risks of deeper diving and how to avoid and prevent accidents

Of course deep diving needs to be taken seriously as the risk of decompression sickness ‘the bends’ does increase. Also the effect of nitrogen narcosis increases with depth. You also breathe more air the deeper you go so this needs to be taken into account. Divers can easily avoid and prevent all of these things with careful planning and consideration. Never push your limits and ensure that you take the right course for you to achieve your depth goals! So guys whether your goal is 30mts, 40mtrs, 60mtrs or even 100mtrs they can all be made achievable with diving. I for one can tell you there is nothing quite like the thrill of achieving your new depth goal, especially with all the planning taken to achieve it.

Advantages of deep diving

There are many creatures you will see at deeper depths that can’t be found at shallower depths. On tropical reefs healthier coral reefs are often found at greater depths. This due to less exposure to the sun and also human waste damage. Another factor is commonly you will find that many wreck dives are at very deep depths and always attract many interesting marine animals. So deep diving isn’t just something to brag about to your buddies but also a chance for you to experience things not seen by any other people!

Final note

So guys as a final note, before you go deep make sure you ALWAYS, no exception, have the correct certifications and qualifications to allow you to do so. You must also always ensure you have the correct equipment you need and you are diving in good conditions. This will allow you to perform your dive easily and safely! You must always prepare and organise properly before any dive but this applies even more so for deep dives. It is vitally important to plan everything and take all possible circumstances into account.
