No doubt, night driving is a risk, but how exciting it is for divers!
If you consider all the nuances and prepare well, the dives will be quite safe.
- First, you must already dive into the area during daylight hours.
- Secondly, you do not need to take huge lights with high power, just enough special lighting for night scuba diving. T
- hirdly, make sure that the equipment is the same as for your day dives. Special changes are not necessary, because you can only harm yourself that way.
Lighting for night diving
If you decided to dive at night take flashlights for 30-50 watts. The main thing is that they can be easily operated, the glow is long, and they are enough for both changing clothes and on the way to the place where you will dive.
It’s also important to check the angle of the flashlight’s reflector. For example, if you decide to use a wide-angle reflector, you will feel like a pedestrian on the highway in dense fog in a body of water with muddy water. You’d better use narrow sector illumination in such water bodies, it will allow seeing all details and avoid collisions with objects.
Keep in mind that flashlights can easily get lost in the dark water, fall out of your hands accidentally. Therefore it is better to take two devices for lighting. Also do not wave the flashlight in different directions, trying to illuminate everything in a row. Smooth and unhurried movements will help you to see all the nuances, to orient yourself in the dark.
Some of the basic requirements for flashlights are sturdy construction, low battery signal, good shockproof glass. The rim of the reflector should be protected by a special design against knocks or scratches from stones. Of course, the flashlight must be able to turn on and off easily, even if you are wearing gloves or a tight suit. Also, check that the flashlight has a device that allows you to charge it quickly, this will make it possible to dive one after the other without long pauses.
If without good lighting your swim can be extremely unsuccessful, without the proper equipment it will not happen at all.
First and foremost, pay maximum attention to your safety. In case of emergencies, your partners will not be able to quickly find you in the dark water. That is why you should buy beacons and luminous tubes. The first are small devices that can brightly flash for about 15 hours at intervals of a few seconds. Such beacons can be seen on the gangways of boats that are used for scuba diving night.
Glow tubes work on a slightly different principle. They are not powered by batteries, but by a chemical reaction inside the tube. With a strong bend, the two types of liquid mix inside the tube structure, and a rather bright glow appears. It is best to use the device for the first three hours, then the light begins to become dim, and after 10 hours it disappears at all. By the way, the brightness of the glow is also affected by the temperature around. If the water is cold, the objects will be seen worse, and the brightness will be almost minimal.
Such tubes will help to find a diver if something happens to him. In warm water, the tube is visible from 100 meters away, so you can dive without fear of being lost from sight by your diving partners.
Rocket signals can also be useful. If there is an emergency, they can help the rescue services find your boat or boat. The only nuance is that rocket signals cannot be transported in an airplane. Therefore, if you dream of night diving abroad, then from such an option will have to give up.
Take with them also acoustic signaling means, such as whistles or sirens. When diving includes a knife in your equipment. It is useful if you get entangled in a network or fishing line. You should know your equipment “by feel”. I.e. you could find certain details even in total darkness.
