What this video covers
A radar screen between Torrevieja and Alicante shows coastline and fish-farm returns as yellow echoes.Watch The Electronic Bearing Line (EBL) function is demonstrated: a line is drawn from own-ship to a target echo, and if that target moves along the line without deviation, the bearing to it remains constant — the definition of a collision course.0:23 The technique requires no additional instruments beyond the radar's built-in EBL tool. Selecting the EBL, placing it on a contact, and monitoring whether the contact tracks along or drifts off the line gives an immediate collision-risk assessment.0:23 A constant bearing with decreasing range means action is required; a target that drifts off the line is not on a collision course.0:50 Fish farms appear as clustered point returns and illustrate how the radar distinguishes fixed hazards from moving vessels in coastal waters.Watch
