Deep Diver Specialty course

Divers choose to dive deeper to observe marine life that you would not normally see at shallower depths.
It is quite common for wrecks in deeper water to be better preserved as, the greater depth results in less damage resulting from surge than at the surface.
On many tropical reefs it is commonplace to find brilliant, healthy coral at greater depths due to less exposure to the sun and other shallower pollutants. Many fish and other marine creatures also prefer greater depths only rising to the surface shallower waters at night time.
