You will enjoy amazing nocturnal creatures that have emerged from their homes, for example:
- Octopuses leave their shelters and move across the reef.
- Squid zip in and out of sight.
- Lobsters walk in groups on the ocean floor.
- Fish settle down into reef gaps to sleep for the night.
- Sharks swim through the dark, hunting for food while Coral polyps open to grab drifting zooplankton.

In your Open Water course, you will learn that color is absorbed by water while you descend. But in your night dive, You’re bringing back light as you go.
This leads to an illuminated scenery in a dazzling show of color. The favorite feature for many night scuba divers is the bioluminescence. Cover your light then wave your hand around to see a fantastic glow of blue and green specks that resembles a field of fireflies.

Lighting the Depths: Essential Gear for a Safe and Brilliant Night Dive
A good light -without doubt- is a must in order to enjoy your first night dive. Dive lights are sealed in waterproof, pressure-resistant casings. They’re tough and built to withstand underwater conditions. Light technology has drastically improved over the years.
The life of the battery becomes longer and the bulbs are burning brighter than ever before. Your local dive shop can help you sort through the many dive light options. Attach a bolt snap to your light so you can clip it off if needed.
Be careful not to shine your buddy in his eyes with the light. You need both a primary light and a backup light.
If your primary light fails, your backup light will be enough for a safe controlled ascent. End the dive if any team member’s light fails. Light sticks or marker lights are also considered handy gear. You can attach the light sticks to the tank valve.
This guarantees that both you and your buddy become easily identifiable underwater. Clip marker lights to the anchor chain or exit to guide you on your way back. Putting a marker light on your dive flag makes it easier to find each other if you get separated.
Finally, compasses are very essential tools to navigate underwater safely. Purchase one with a glowing dial. You can use them easily when they stay illuminated after a brief flash of your light.
