Dive Briefing
"The dive at Carlson Wreck (Oil Tanker) begins with a controlled entry and a short transfer from the nearest base, with the guide giving a full briefing on the site layout, expected marine life and emergency procedures. Descending toward a 50 m oil tanker sitting as an artificial reef in 18 to 30 m, with a broad hull and superstructure, divers are immediately surrounded by batfish, humper red snapper, red lionfish, soft coral gardens, with the reef revealing more detail the closer you look. The maximum depth reaches about 30 metres, while the average depth sits near 24 metres, so gas planning and a dive computer keep the profile safe and comfortable. Currents are described as mild, and the guide chooses the entry time to make the most of slack or mild flow, using a reef hook or DSMB when needed. The topography offers natural swim-throughs and ledges that shelter larger animals, and the open water above the reef often holds cruising pelagics. Throughout the dive, neutral buoyancy protects the fragile coral, and the group stays close to the guide to manage depth and any surge. The safety stop is completed in open water on a DSMB, and the boat follows the bubbles to collect divers at the exit point for a relaxed return to base. A morning dive gives the calmest conditions and the best light on the encrusted superstructure"
