Safety notes

Dive only after a local current assessment. Maintain the planned depth and side of the reef, stay close to the guide and carry an SMB and audible surface signal.

Dive tips

  • Follow the local guide’s site- and tide-specific briefing.
  • Agree a maximum depth within certification limits; the published site range is 5–40 m.
  • Maintain neutral buoyancy and avoid contact with coral, artificial structures and the seabed.
  • Dive only after a local current assessment. Maintain the planned depth and side of the reef, stay close to the guide and carry an SMB and audible surface signal.
  • Treat wildlife encounters as possible, never guaranteed, and give animals space.

Underwater photography

Wide-angle equipment suits the reef structure and larger marine life. Set exposure before entering current, keep the rig streamlined and secured, and prioritise depth, gas, buoyancy and buddy contact over the photograph.
