Make your night dive enjoyable by doing advance preparation. The prep work ensures your dive party's safety and allows you to focus on the adventure itself. The better you plan the more prepared you are for unexpected problems, whether it is foul weather or a piece of equipment that fails.
Night diving is a form of recreational diving that is growing in popularity. Divers enjoy nocturnal adventures because many sea creatures are most active at night.
But night diving has a lot of risks. Scuba light failure can be the most dangerous, because the diver can lose his or her bearings and cannot monitor gauges. The diver can become separated from a diving group, a dive boat or drift farther from shore.
The protocol for night diving is to carry three dive lights -- a primary light, backup light and marker. Divers use a larger light with a broader beam as their primary light. They have a flashlight or smaller pocket light as their backup. A marker light is attached to the diver - usually near the tank valve - so he can be spotted when floating at the surface.
Although not required, divers may also carry a strobe light, which is used for a signaling device. Strobe lights can very helpful to a diver lost at sea.
Whether you should power your dive lights with rechargeable or disposable batteries depends on how careful you are at maintaining your equipment.
Diving lights that use disposable batteries burn longer and are cheaper to buy. But they aren't as convenient and are wasteful.
Rechargeable batteries cost more, and require you to perform the extra task of recharging after a dive. You also will want to be extra careful with your rechargeable batteries and not lose track of them.
A benefit of rechargeable batteries is that they pay for themselves over time. Divers who frequently use underwater lights and take good care of their gear may prefer rechargeable batteries. If you are a beginner or don't want the extra task of recharging batteries, then stick with disposable ones.
External strobe lights can bring out vivid colors in your underwater digital photography. External strobes can be mounted on an arm away from the camera body. While flash cameras are more convenient, they can create a phenomenon called backscatter. While illuminating the fish or coral you are trying to photograph, built-in flashes can cause the background to look underexposed or shadowy. An external strobe creates an even field of light.
An alternative underwater light that works well for closeup images or movies is a video light. Video lights can bring out the underwater world's natural colors.
Of course, you can shoot underwater photos without any artificial light. Your photos will look fine, but they might not be the quality you expected. The background tends to look blue in the natural light underwater. Your best option is to invest in an external strobe light that you can attach to your camera or hold to shoot photos worth framing.
Cave diving is considered one of the most dangerous forms of scuba diving, though devotees would disagree. They say the level of expertise, training and experience required for cave diving draws only the most skilled people to the sport.
Cave divers follow strict guidelines that are considered the five commandments for safe passage.
Dive lights are not just for remaining safe while night diving. They can be used for cave diving, wreck diving, peering into holes, or illuminating the brilliance of reef fish. Consider different styles of dive lights. UK lights like the Mini Q40 UK dive light are so compact, you can carry them in your BC pocket.
Plan your night dive to start at twilight. Not only do you get to watch the transition from dusk to darkness, you can orient yourself and rely more on natural light to see the underwater world around you.
Jarring can damage underwater lights. So when you leave the dive boat, ask someone to hand the strobe light down to you.
Make sure you strap your scuba light to your wrist. The last thing you want to do is drop it. Dive lights sink and in the panic of the moment you are unlikely to find them. Of course, you will be carrying a backup light, but just use that to navigate your way back to the boat.
Understand that it is easier to get disoriented during a night dive. You may not realize how quickly you descended or how far you have drifted from the dive party. Stay close to your buddy and do not attempt deep-water dives at night.
Try switching off your light to gauge the ambient light around you. The stars and moonlight may provide enough glow to illuminate the underwater theater of fish and sealife.
There are a variety of lights for illuminating dives, and they serve a lot of different purposes. Consider the dive light's shape and size as well as its switches and grip. Bulb types include xenon, argon, krypton, HID and LED.
Look for popular name brands like Pelican, Nemo and Princeton, which have a reputation for quality and reliability in diving lights.
Here are several kinds of dive lights you may want to add to your shopping or wish list:
Cave divers carry three lights -- a primary dive light and two backup scuba lights. If one underwater light fails, the backup light is used to leave the cave, and the remainder of the expedition is immediately called off. When shopping for dive lights, check the burn time, beam width, bulb and depth rating. There are many variations of lights to choose from, depending on your diving needs.
