When choosing a dive spot keep in mind that you do not want anything uncontrolled happening at a night dive. Therefore, pick a dive spot with as little current as possible, and no surf or other obstacles that can interrupt the dive. You also need to make sure that the spot you choose is easily accessed when it is dark. Easy entry and exit is important, especially if you need to carry your dive equipment.
Equipment for Night Diving
It is important that you set up all of your dive equipment during the day or in sufficient light prior to the night dive. This will ensure that all of your equipment is set up properly, and that you will not forget anything. You need to use a dive torch with strong power and long battery life. When choosing a dive light you should consider the beam width, burn time and the depth rating. Here are 5 Pieces of Equipment to Improve your Safety while Diving. Always keep a spare flashlight in case your primary light runs out of batteries or stops working. A small flashlight can be stored in the BCD pocket. It is also a good idea to have a chemical light stick or a battery powered marker, which can be attached to your BCD or tank, for easy recognition. The light can also be attached to the boat, anchor line or buoy so you can find your way around. Use familiar equipment that you have tried during a day dive. Do not go on a night dive with brand new equipment that you do not know how to use.
Get a Buddy for you Night Dive
Getting a buddy for a night dive is a must. It gives you great mental support. Keep in mind, however, that you and your buddy need to keep an extra eye out for one another. It is easy to get lost at night. You can also use a short buddy line to minimize the risk of being separated. Be careful where you point your light. It is a good idea is to keep your light facing down toward the bottom so as to prevent shining it in other divers’ eyes.
It is a good idea to go diving at twilight, this will make it easier for you to adjust to the darkness gradually. Another adventurous option is diving down just before dawn. It is unbelievable to watch the beauty of marine life when they awaken. Plan for a shorter dive, compared to daytime diving, for safety reasons.
Signals on Night Dives
Learning to use light signals is crucial for a night dive. For example, moving the light up and down is for attracting a buddy’s attention. Waving from side to side indicates that something is wrong. Waving the light in a circle shows that everything is fine. Making a signal while holding the light toward your hand helps other divers to see it better.
