Scuba diving is a spectacular experience on its own, but you can enhance it even further if you decide to dive at night. A night dive is in many ways similar to diving in the day, but there are some basic preparations and precautions you need to take beforehand.

However it is not that complicated as it may sound, if you keep a few guidelines you can easily master a night dive. This article is a handy collection of the things you may want to know about night diving.

How is night diving different from day dive?

First of all, the water is normally pitch-black, apart from places that you shine a light on, which practically means you will only see things that you point your light on.

However, this is actually a lot more fun than it sounds because only during a night dive you are going to see the real colors of corals and marine creatures. When the sun is up, the water absorbs all the light that penetrates into it by the time it would reach coral reefs. This results in significantly dimmed colors underwater during the day.

At night time however, when you point a light at something, the water does not absorb most of the light which means you will be able to see true colors. This is also great for underwater photography.

Another reason why you should consider night diving is the different marine life. Most nocturnal sea animals are invisible in the daytime, or if they are around, they are very inactive.

While on a night dive, you are going to be able to see these creatures and to see the ocean show a completely different face. Sharks are a very good example of this. You are, of course, able to see sharks on a day dive as well, but most species hunt at night. So remember to bring a dive knife as a precaution. That means you are going to see these animals behave as you never have before which is a very unusual and thrilling experience.

How should I prepare for night diving?

Start with the light.

You should have a primary and a backup light. In terms of the primary light, it is worth getting one that has adjustable brightness as the brightest is not always the best.

In fact, if your light is not very light you will be able to see more marine life as you do not scare them away. Make sure you have a smaller backup light with you as well if the first one breaks, and if that happens, interrupt your diving and return to the liveaboard. 

It is also important to recap the signals with your diving partner and to agree on which ones you are going to use.

During a night dive you are likely to not see each other only the other's light so this can be vital. Also be careful not to shine your light in their face as you can ruin their night vision. 

Another thing to do before diving is to place lights on the liveaboard or shore you are diving from to find the way back. This is important because you will not be able to see your surroundings very well.

The last thing is to dive on the site during the day before to get familiar with the surroundings. It is good to vaguely know what is around and you can also find the spots you want to take a better look at in the dark.

It is especially recommended if this is going to be your first night dive as it is going to make you feel a lot safer, which means you worry less and have more fun.

Do I have to get extra training for night diving?

You do not necessarily need a specific night diving certification, but you will need to be able to dive beforehand.

If you have not dived in the night before, you must go in a group with a guide when you dive for the first time. The guide will explain you everything you need to know about how to use the lights and will also teach you how to signal.

These services are available at many resorts all around the world.Night diving can be exquisite fun if you prepare properly. You will see the ocean in a way you have certainly never before. The colors and the marine life are going to be a unique, once in a lifetime experience if you decide to go ahead and try night diving.
