Night diving offers a unique way to see a 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 get started, learn about the equipment you'll need and how to choose a dive site.
Bioluminescence
By turning off your scuba torch, you can enjoy the wonders and beauty of bioluminescence while night diving. Simply wave your arms in the water and turn your scuba torch off. When you move your arms about the water, bioluminescent plantton will turn blue. This phenomenon occurs when certain chemicals are disturbed by vibration and generate light.
Many marine species use bioluminescence for communication and to attract mates. Syllid fireworms for example live under the seafloor in mucus tube and then return to the surface when the full moon is over.
Be aware
If you have never dived at Night before, you need to be careful. Avoiding excessive light and using dive lights are two of the precautions. These lights could cause night vision issues for other divers. You may also be at risk of developing cardiac abnormalities by exposing yourself to the lights.
A buddy team is essential for you to avoid excessive light exposure. When night diving, a buddy partner is essential. You will have a buddy who can help you spot potential subjects. Practice hand signals with your partner prior to you go on the dive. Your buddy should be able to correctly use the light. Avoid shining the light directly on subjects. Instead, aim it at their hands.
Equipment
You will need special equipment if you plan to do a night dive. First, make sure that you have backup lights. This type of light is usually small enough to carry in your pocket. You will also need a modeling lamp, which is a light that is attached to a flashlight. 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.
Second, you will need a high-quality dive light and an accurate compass. You will also need a light that gives you the ability to communicate with other divers. You will also need to know how your diving rig works. You must also be able to dive at night. You should immediately get out if you feel unsafe. It doesn't matter if it is bad weather, lack of training, or unsafe water conditions. You might end up in a dangerous position. Additionally, you should avoid any substances that impair your judgment.
Selecting a dive site
When you're ready to dive at night, you'll need to choose a night dive site that's calm and shallow. It's not a good idea to add more gear or take a camera on your first dive. You will feel more comfortable and have a better night dive. You can start out by diving in the twilight and go deep later on.
It is important to do your research before you decide on the night dive site. There are many factors to consider when choosing a night dive site. If you've never done night diving before, you'll want to choose a site that has a good history of diving at night. The day allows you to easily locate the dive site and navigate around it. It's easier and warmer to dry your equipment during the day.
Choose a night diving buddy
Choosing a night dive buddy can be a challenge. The water changes quickly after sunset, so you must slow down to avoid hitting anything. Night diving is required to be more comfortable in the water. Feeling cold is something that no one wants. This can make diving unpleasant and uncomfortable.
Discuss your dive plan, and any special instructions, with your night dive buddy, before you dive in darkness. This includes how you plan to complete the dive. Talk about how you will communicate.
