Night diving can make communication difficult between divers. It is essential to establish clear communication between divers during pre-dive briefings and then double-check them during dive. Also, it is a good idea to choose sites that are shallow and don't have strong currents. For optimum safety, divers should opt for sites that are well-lighted.
Scuba diving at night
Night diving is a wonderful way to discover the underwater world. Night diving offers a safer alternative to daytime diving. This will allow you to see things you wouldn't normally be able, such nurse sharks, lobster, and others. It is important to be safe when you dive at night.
Safety
Night diving has many safety concerns. The first is the loss of visibility. A current can sweep you away if you can't see the underwater environment. A few dive lights can help reduce the risks associated with night diving. Attach them to your BCD/diving tank to ensure you see clearly where you are.
Equipment
The essential pieces of night diving equipment are lights and submersiblepressure gauges. These lights will allow you to see clearly and offer safety for other divers. The submersible pressure gauge will alert you when your oxygen level is low.
Get a certification
Consider obtaining a night dive certificate if your interest is in learning about night diving. Night diving is an extremely popular activity and certification in this field has many benefits. However, obtaining this certification requires a certain amount of gear. You should bring several items with you to night dive, including a primary and dive light.
Animals that emit their own light
Bioluminescent organisms emit light in two ways. The first is by absorbing light from the surrounding environment. The second way is by radiating light back. Bioluminescence, also known as photoluminescence, is a complex chemical reaction that requires the involvement of a specific class of proteins. The proteins that generate the light are called luciferase. These proteins produce cold light that emits very little heat. Bioluminescent organisms wouldn't survive if there was too much heat. Light is emitted by most animals and humans to a limited degree, but it is rarely noticeable.
Commuting with your buddy on a night dive
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. You can also hold the light in your hand and wave to your buddy. This will help your buddy see the light better than if he were only holding it.
