Beginners appreciate the cave systems that have no flow, and an average depth of 35ft that allows a relaxed dive if desired. These dives include the opportunity for complex navigation, the discovery of the bones of animals that reach back 5000 years, and the possibility to surface to enjoy the stunning formations covering the ceilings and walls of the vadose areas.
Search. Once you go out on the boat, the ocean can be rough and you will discover that finding a location for the primary tie off in open water and a safe location to exit the water can be demanding. The proper positioning of the tie off and knowledge of the water movements is the key to a relaxed dive under these circumstances. The diver and the team need to understand the water movements in order to place a tie off without losing a lot of energy while working or finning against the current.
Current can be encountered in several systems in Florida or the Bahamas where the tidal changes need to be considered, avoiding finning against the flow on the way in and out of the system! Depending on the season or tidal changes in Sardinia, the flow may need to be included in the air planning and calculations prior to the dive.
Depths that reach down over 300 feet require complex gas planning and management. The staging of decompression tanks and dive rig management by the surface support team of ProTec Sardinia are an important part of the dive plan for the divers or the students taking a technical cave course.
