Scuba diving

Scuba diving takes you deeper below the surface than snorkelling and uses specialised breathing equipment with a very different set of safety procedures. Choose an operator that clearly explains health requirements, planned depth and underwater communication before you agree to dive.

How to schedule?

Before the dive, accurately disclose your current health, medications and previous diving experience. Ask the instructor how the equipment works, what depth is planned, how to equalise ear pressure and what the emergency ascent procedure is. If you are flying afterwards, the surface interval before a flight needs to follow appropriate professional diving guidance for the actual dive profile.

This is a technical activity, not simply deeper snorkelling
The value of scuba is the experience of breathing underwater, observing marine life in three dimensions and learning to move in the underwater environment.
Beginners should favour an operator that provides:
• A clear briefing.
• A health questionnaire.
• Properly fitting, checked equipment.
• An appropriate instructor-to-guest ratio.
• A procedure for panic or early termination.
• Transparent information about planned depth and duration.

What may be different

Wearing a cylinder does not mean you simply jump in and explore freely. Pressure changes and time underwater require strict procedures. If you develop ear pain, panic or an equipment problem, signal the instructor and stop the dive. The appropriate interval before flying depends on the actual dive profile rather than one universal number for every diver.

Ask about safety standards before asking about photographs
Know who is supervising, what relevant certification or training they hold, how many guests they supervise, how equipment is checked and what happens if a participant becomes uncomfortable underwater.
Do not choose a dive simply because the photos look good or the price is lower. In an underwater activity, supervision quality matters more than the number of photo stops.

Before the trip

Disclose relevant heart, respiratory, ear, nose or sinus history and any medication you are taking.
Signal and stop the dive if you develop ear pain or any concerning symptom underwater.
Do not schedule a flight too soon after diving; follow appropriate professional guidance for your dive profile.
Check the operator's diving credentials and the condition of its equipment.
