Why PADI Night Diver?When you go night diving you'll see a whole new world. Even your local dive site takes on a new personality at night, as many underwater creatures and plant life (different from those you see during the day) are active at night.
What do I need to start?-PADI Open Water Diver or Junior Open Water Diver certification (or qualifying certification from another organization)
-Minimum age: 12 years old
What will I do?You'll learn night dive planning, organization, procedures, techniques and potential problems. You'll also learn how to control your buoyancy, navigate and communicate at night. Since many of the plants and animals you'll see are different, you'll also get an introduction to nocturnal aquatic life.
How long will it take?-Recommended Course Hours: 12
-Minimum Open Water Training: three dives over a planned period
What will I need?-PADI Night diver Pack, which includes manual, video and log insert
What can I do after this?Your Adventures In Diving Night dive may count towards the Night Diver Specialty course at instructor discretion. In addition, the Night Diver Specialty course counts as one of five Specialty courses required for your Master Scuba Diver certification.
How much will it cost me?Your night diver course will cost you only € 160,00 and includes 4 night dives and torch hire.
What you will see and do during the course?You will first have some home study with the Padi Night Diver manual. After completing the knowledge review from the manual, we will take you on 2 great night dives. On these night dives you will see all the night predators out hunting. Also all the normally reef fish you will see out during the day, will be asleep. They will be tucked into any rock or over hang that they can find, in order to stop the night predators find and eating them. You will also have to make some very easy navigation with compass and we will talk to you about the possible torch options for night dives.
IntroductionNight dives can be great fun, but they're not without risks. Make sure that all divers are fully aware of the additional risks associated with dangerous creatures, for example, Sharks and Lion fish are much more active at night.
Ensure the following conditions are met:
-Good surface visibility, don't dive in fog, heavy rain etc.
-SMB's should have lights, strobe or light sticks on
-All divers to have main and backup torch
-A restricted diving area
-Minimal accidental penetration risks.
-Exit points are lit with coloured lights (to distinguish from other lights)
Night visionTry and get to the dive site before night fall, so that conditions and entry can be checked. Before arriving at the dive site warn about night vision. It takes at least 15 minutes of near-darkness for our vision to adjust to low light. A torch beam shone in the eyes or car headlights can destroy night vision for another 15 minutes. Advise that all divers check torches before kitting up and turn headlights off and use dim light while getting ready. When ready to dive, eyes will be well adjusted for night vision.
TorchesDivers should have two torches each, one main and one backup, Avoid head-mounted torches on night dives as one glance at your buddy destroys their night vision. On the dive never turn the torch out as the bulb is most likely to blow, when it is turned back on. If want to black out torchlight (e. g. to see photo plankton flash), put the torch against body or cover with hand. Use torches or strobes to mark decent lines and entry/ exit points. Also you can use glow sticks to mark diver and have different colours to mark the guides and instructors.
If the torches have rechargeable batteries, make sure they are fully topped up. If they're disposable, put a fresh set of batteries in regardless of the amount of use.
When carrying the torch into the water, hold it with the lens pointing down. In this way if the torch should flood with water you will see water appear in the lens first and may be able to save the whole torch from being flooded. As torches can be quit costly, this may save you money.
SignalsSignal can be made with the torch beam on the seabed, where your buddy is looking (not in face).
Common signals include:
-Rapid side-to-side movement underwater = attention, look this way
-Rapid side-to-side movement on the surface = I have a problem help me
-Slow large circle = OK (like the normal finger and thumb circle, hand signal)
-Steady beam straight up at surface of water - alarm to surface cover (most torches balanced to do this if let free for this reason)
-When giving hand signals, shine torch at your hand so buddy can see it (tricky if two-handed signal - tuck torch under arm)
-It is important for buddy to confirm signal by repeating it as it is easy to misunderstand in dark
Buddy checks are important as it is easy to miss things at night. Go through the checks religiously and test things work properly. On the dive always pay special attention to navigation as there are a lot less cue to use, than with sunlight. It is easy to get disorientated and to go deeper than you intended as you loose the normal darkening cues that you would get in the day. Watch your depth gauge often and check buddy is too. The same lack of light cues, make it easier to go inside things like wreck or caves without realizing. Shine torch all around regularly to check.
