Practice these signals with your diving group during pre-dive briefings. Consistent practice ensures that everyone understands the meaning of each gesture, reducing the risk of miscommunication underwater.

Using hand signals helps maintain safety and allows you to share observations, like pointing out marine life or indicating a problem with your equipment. This mutual understanding enhances the safety and enjoyment of your diving experience.

Remember to keep your signals visible. Use slow and deliberate movements so that your dive partners have enough time to recognize and respond to your messages. This clarity can be vital in various underwater scenarios.

5) Monitor your oxygen levels

Keeping a close watch on your oxygen levels is crucial when diving. Always use a reliable dive computer or oxygen monitoring device.

Check your equipment before each dive to ensure everything is functioning correctly. Make sure your tank is filled and all connections are secure.

Regularly glance at your dive computer during the dive. This helps you stay aware of how much oxygen you have left.

Set personal alarms on your monitoring device. These alarms can alert you when your oxygen levels are getting low.

Communicate with your diving buddy about your oxygen consumption. Consistent check-ins can prevent emergencies.

Be aware of your breathing rate. Faster breathing can deplete your oxygen supply quickly.

Plan your dive duration and depth based on your oxygen levels. Always aim to surface with a safety reserve of oxygen in your tank.

6) Avoid Alcohol Before Diving
