To overcome poor
visibility, divers tend to bring with them
underwater lights (underwater torches) which is easily
purchased at any diving shops and the variety
you can choose from is unlimited since they come
in all shapes, sizes and powers. The type of
underwater lights that you bring along depends
on where and when you are diving.
Large and powerful
underwater lights are used to illuminate divers
and wrecks in daylight. When you are diving at
night, it is better to bring low power
underwater lights in order to prevent from
scaring the shy marine creatures away and
sending them into hiding. This type of low power
lights are usually powered by alkaline batteries
while the stronger lights use rechargeable
nickel-cadmium batteries.
