Night diving is a way to experience a completely different underwater world. The underwater environment is different during the night, and many marine animals are nocturnal. To experience this special diving environment, you will need to prepare yourself for the experience. Before you dive, make sure you know what equipment you need and how to select a site.
Bioluminescence
If you are looking for the magic of bioluminescence, you can try night diving by turning off the torch on your scuba gear and waving your arms into the water. When you move your arms about the water, bioluminescent plantton will turn blue. This is caused by certain chemicals being vibrated to produce light.
Bioluminescence is used by many marine animals to communicate with one another and attract mates. Syllid fireworms, which live in mucus tubes under the seafloor and return to the surface on the full moon, are an example.
Be aware
If you've never dived at night before, there are several precautions that you must follow. These precautions include avoiding exposure to excessive light, and avoiding the use of dive lights. These lights can affect the night vision of other divers. Exposure to these lights can also increase your risk for developing cardiac problems.
A buddy team is essential for you to avoid excessive light exposure. Night diving requires a dive partner. A buddy can help you identify potential subjects. Before you dive, practice hand signals with your buddy. Your buddy should be able to correctly use the light. You should not shine light directly onto subjects. Instead, aim the light at their hands.
Equipment
Special equipment is required for night diving. You should ensure that you have backup lights. This type light is small enough that you can carry it in your pocket. A modeling light, which attaches to your strobe, is also a good option. Divers used to use chemical glow sticks to navigate back to their boat after a dive. However, environmental concerns led to the switch to battery-operated signal light with different colored lenses.
You will also need a quality diving light and a compass. A light that allows you to communicate with other divers is also essential. You will also need to know how your diving rig works. You should also feel comfortable diving at nights. You should not dive if you aren't feeling safe. It doesn't matter if it is bad weather, lack of training, or unsafe water conditions. You might end up in a dangerous position. You should avoid substances that may impair judgment.
Choose a dive location
Choose a night dive location that is shallow and calm when you are ready for night diving. It's not a good idea to add more gear or take a camera on your first dive. It will be easier to get comfortable, and your first night dive will go well. Start out in the twilight, and you can go deeper later.
To choose the right night dive site, you'll want to do your research. There are many factors to consider when choosing a night dive site. You'll need to look for a site where night diving has been done before. You can use the day to locate and map the dive sites. You can also dry your equipment more quickly and warmer during the day.
Night dive buddy
Choosing a night dive buddy can be a challenge. The water changes quickly when the sun goes down, and you need to move slowly to avoid hitting objects. Night divers should also be prepared for cold water. Feeling cold is something that no one wants. This can make diving unpleasant and uncomfortable.
Discuss your dive plan with your night buddy before you dive in the darkness. This includes the order you wish to complete the dive. Additionally, you should discuss how and when you will communicate.
