CLEAN : Indonesia Singapore hunt for missing jet

The video tutorial covers various topics, starting with an introduction to workers compensation insurance and the types of products available. It then shifts focus to recording modes and equipment, particularly the use of underwater locator beacons. These beacons emit acoustic signals when submerged, which can be detected using a hydrophone. The process involves submerging the hydrophone and rotating it to capture signals, with an operator on a boat listening for the detected signals.
