The time spent scuba diving at night isn’t like any other time that you will spend. There is much more activity on the reefs after dark and the abundance of different sea life that can be seen is phenomenal compared to diving during the day. However, anytime you dive you need to make sure that you properly equipped and night diving is no different. Here are some things to remember to keep yourself safe when scuba diving at night.
The dives done during the night should be kept fairly shallow. As a general rule no more than sixty feet with the majority being thirty to forty feet deep to ensure the safety of the dive better. When first going night scuba diving and with all following dives the more familiar you are with the area the better. The location of the dive should be chosen beforehand. It is possible to either go to a location you are already familiar with or if you want to you can chose a new location and set up an appointment to take a dive there in the daytime before your first night dive. It is important to dive under the best possible conditions when diving at night.
All equipment on a night dive should be some that you have previously used and are sure that it is in proper working order. You do not want any surprises once you are underwater. All equipment should be set up in a well-lit area so that it can be inspected one last time before beginning the dive.
When going scuba diving at night you need to be able to see. You will need at least two lights; one main light and another in case the first light stops working for whatever reason. You will use the lights until you get comfortable at which point you may find yourself turning them off and letting your eyes adjust to the darkness.
When night scuba diving some people will use glow sticks on their tanks to be able to find others underwater. There are some places that do not allow these due to the containment of chemicals within them.
Hand signals should be learned before attempting a night dive. There will be an inability to see the hands underwater at night. The dive master will tell you what the signals are before you go on the time more than likely. A light should be directed at the hands so that others can see them. Moving the dive light works for some signals as well and moving it in various directions will indicate different things.
You need to take care when using your underwater lights at night, be careful that you are not shining into the face of others and blind them, as this can put them in extreme danger even if it is only a temporary blindness.
Night scuba diving is fun and different, just remember to be careful and take your time to ensure your and your buddy’s safety and to allow you to fully appreciate the beauty under the water.
