1) Keep the flashlight as simple as possible.
Many divers grasp at the flashlight as their only guarantee of safety. This is a mistake. When you approach the bottom, turn off the flashlight and see the natural underwater light. Allow your eyes to get used to the darkness and you will be pleasantly surprised.
The diver’s light sources are the moon and even the stars, so you don’t need a flashlight. Without including a flashlight, you will be able to see even more fish, and coral polyps and actinia will extend their tendrils even more.
2) Knowing the signals is very important
Hand signals at night are difficult, it’s almost impossible, so a flashlight will serve you well. The outline of the circle means “all is well,” the movements from side to side call for attention, and up and down call for help.
3) Use the strap
Fasten the flashlight to your wrist with a strap to avoid it falling off and losing your primary means of illumination. Most flashlights have poor buoyancy. If you need to free your arm, switch the flashlight off before you drop it in order to avoid dazzling other divers or creating a false signal.
4) Do not turn the flashlight on the surface
On the surface, some flashlights get so hot that they melt their reflectors and lenses without the cooling action of water. To preserve the life of your underwater flashlight, use a flashlight on the surface.
5) Don’t jump with the flashlight in your hand
Ask someone to hold it. A sharp jet of water may make a crack in the glass and water may seep in.
6) Stay close to your partner
7) Check your equipment as often as possible
Without a clear picture of the condition of your equipment you can easily be swept up or down by the current without even realizing it. If necessary, never neglect the use of an air chamber.
8) Start night diving at dusk
This way you can see two worlds at the same time: The underwater The underwater world at dusk and the gradual arrival of total darkness.
9) Be as inconspicuous as possible
When diving at night diving it’s best to keep a low profile on the bottom. You’re here to see the underwater show, so why not prolong it as long as possible?
Best of luck!!!!!
