Check dive意思
"Check dive" is a term used in scuba diving that refers to a dive that is conducted to ensure that all equipment is functioning properly and to assess the conditions of the dive site before beginning a planned series of dives. The purpose of a check dive is to identify any issues with the diver's equipment or to become familiar with the local conditions before proceeding with a dive that may involve more risk or deeper depths.
During a check dive, the diver will typically perform a series of tests to ensure that their buoyancy control device (BCD), regulator, mask, fins, and other equipment are working correctly. They may also check the water temperature, visibility, currents, and other environmental factors to get a sense of what to expect on subsequent dives.
Check dives are especially important for divers who are unfamiliar with a particular dive site or who are using new equipment. They can help to prevent accidents and ensure that the diver is comfortable and confident before embarking on a more challenging dive.
