Communication is difficult when diving at night. Communication between divers is difficult at night. It is therefore important to have a pre-dive briefing that includes signals and double-check them throughout the dive. Avoid choosing dive sites that have high currents and are shallow. For optimum safety, divers should opt for sites that are well-lighted.
Night diving
Scuba diving at night can be a great way of exploring the ocean floor. Night dives are safer than daytime diving because they avoid dangerous conditions such as strong currents or poor visibility. This will allow you to see things you wouldn't normally be able, such nurse sharks, lobster, and others. There are safety precautions that you need to remember when diving at night.
Safety
There are several safety concerns with night diving. First, there is a lack of visibility. A current can sweep you away if you can't see the underwater environment. To reduce the dangers of night diving, you should always have a couple of dive lights on hand. Attach them to your BCD/diving tank to ensure you see clearly where you are.
Equipment
Night dive equipment includes lights and submersible gauges. These lights will make it easier to see and give you more safety. The submersible pressure gauge will alert you when your oxygen level is low.
Acquiring a certification
Consider obtaining a night dive certificate if your interest is in learning about night diving. Night diving is very popular and it has many benefits. You will need a lot of gear to get this certification. On night dives, you will need to have a primary light and a diver's light.
Animals that can emit their own light
Bioluminescent animals produce light by emitting light in two ways. The first is by absorbing light from the surrounding environment. The second way is by radiating light back. Bioluminescence is a complicated chemical reaction that involves a particular class of proteins. The proteins that generate the light are called luciferase. These proteins emit cold light that gives off very little heat, which is necessary because the bioluminescent organisms would otherwise die if they had too much heat. While light is visible to some extent in most animals and humans, it is usually not noticeable.
You and your buddy can commute together on night dives
Communication is key during night diving. To alert your buddy, you could use hand signals like flicking a flashlight in a circular motion to communicate. Or, you can simply hold your light near your hand and wave it to your buddy. This will ensure your buddy is able to see the light more clearly than you would if you were just holding it.
