Enhance your diving experience with speciality courses

This week has been an great week at DJL. Some of our Divemaster trainees this week wanted to further their diving education by doing speciality courses including wreck, deep, enriched air and oxygen provider.

Wreck speciality

The wreck speciality course is probably my favourite to teach and includes mapping the wreck, looking for possible entry points and potential hazards. The students also learned how to use reels to tie off on entry points and how to keep a continuous line so they never lose the line and therefore the way out. Of course we always take torches in and the visibility inside the wreck is very good but all these techniques are good practice and you never know when they may come in useful. We had several dives on and inside the wreck and everybody loved it.

Deep diver speciality

The deep course is exactly as it sounds, we go deep. Now with deep dives down to 40m, we need to teach more safety procedures because we can spend less time at 40m than we can at shallower depths and we also use our air 5 times faster than if we were on the surface. This certification is a great card to have as it means divers can go deeper than most recreational divers which might mean seeing some awesome shipwrecks or some aquatic life that you might not see at shallower depths.

Enriched air (nitrox) speciality

The enriched air speciality is possibly the most useful as it means we can change the oxygen and nitrogen levels in our tanks which means we can stay down longer at certain depths. It is a very interesting course as students learn more about the effects of gases under pressure so as well as extending their dive time divers are more aware of the effects of gases on their body and therefore much safer divers. Students also learn how to analyse their own tanks so they know exactly what gases they are breathing.

The oxygen provider course is a vital course if anybody wants to work as a Divemaster, it is a legal requirement (in many countries) to have a licence to provide oxygen in an emergency. During this course students learn how to set up the oxygen tanks for a variety of scenarios with different face masks and flow systems for any type of unlikely emergency.

Laurence, Phil, Silvano and Jeff really enjoyed the week and in fact some were so fascinated that some have decided to continue on and do their tech courses which then opens up even more doors to cave systems, deeper wrecks and longer bottom times.
