EANx or NITROX  contains less nitrogen than regular air. Breathing less nitrogen means you can spend more time at whatever depth you choose and also

helps reduce the risk of decompression sickness.

Diving in an overhead environment requires special training. The wreck course teaches you how to enter a wreck safely.  Our HTMS Chang wreck offers safe but challenging wreck experience to advanced divers.

During the PADI Deep Diver course, you'll learn how to plan deep dives.  Gas management and nitrogen narcosis  are critical.  Where an overhead environment is involved then the horizontal distance is also counted as depth, so this course sits nicely with the Wreck Diver Course.

Underwater Navigation takes practice. The course is designed to give the students all the necessary tools to help them become an expert underwater navigator .

Poor Buoyancy, dive insurance companies will say, is the greatest cause of diver emergencies.  It is the most important skill and  perfecting it with training on weight, trim and breathing is essential.

Luckily Searching and Recovering other divers underwater is an extremely rare event.   Missing equipment is, however, common, so learning the methods used to achieve the recovery, produces a happy and cost saving ( or maybe life saving) result

After someone has tried a Night Dive, divers often love it or leave it.  Here on Koh Chang our Night Dives offer a spectacular difference between day and night on the same site.  A great incentive to become a Night Dive Specialist.
