Abstract
A scanning device, particularly for viewing above the core of a nuclear reactor, has links 29 pivoted together at 33 with means 35, 35a limiting relative movement in one sense. At least one link carries a transducer 36, preferably ultrasonic, for viewing. There may be two transducers arranged to view in different directions. The transducers may be mounted in a removable module. A deployment arrangement may have a vertical hollow mast 20 down which the links can be pushed to engage a deflect element 31 to reach an arm 23 from which the links can extend as a cantilever.
