First real test, Chasing GLADIUS mini S

Managed to drop an O-ring while working with fixing a water leak at the docks. Didn’t have a spare so got out the drone and searched. Water depth is around 15 meters, 45 feet. A little bit of current and water not clear enough to see it from the surface (lost visual contact at 6-7 meters). Took a bit of searching but when we found it it was pinched in the grab arm after a few seconds of fiddling about. Great test, and a bit spooky around the docks because of all the mooring chains. A serious problem if the tether gets caught and you don’t manage to find the right way back.
