Specialities are 1-2 day courses focusing on a special kind of diving.
Night Diver:
3 nights/3 dives learning about night dive planning, equipment and navigation.
Night Dives are amazing! The aquatic life is completely different at night and the colours will blow our mind. You'll be surprised to find brighter colours than in day light. This is becuase the daylight isn't strong enough to illuminate colours like red beyond 10m, but your torch is!
If you've done your Advanced course, you will have already done some dives that credit towards a PADI Speciality - Deep, Navigation, etc.
