Our free-diving team are in a tight spot as they search for an irreplaceable piece of jewellery. Crafter Chris is challenged to breathe new life into some damaged spectacles, and social media detective Mui hunts for the owner of a drone that's filled with incredible holiday snaps.

Our detectorists take on the search for a beloved ring, lost on a family farm for nearly half a century, and we try to track down the owner of a mysterious medal washed up on a beach.
