Safety and Conservation Tips for Divers

Safety should always be a top priority when diving, and it’s important to adhere to all guidelines set by your dive operator. Always dive within your limits and never hesitate to ask for assistance if you’re unsure about something. Ensuring you have the proper safety equipment, like a dive computer and a surface marker buoy, can make all the difference in case of an emergency.

Equally important is the responsibility we have to protect the delicate marine ecosystems. Avoid touching corals or disturbing wildlife, and never take anything from the ocean. By diving responsibly, we help ensure that future generations will be able to enjoy these underwater wonders.

Activities Beyond Diving
