Abstract
A pit depth gauge for use as an accessory to an underwater ultrasonic probe omprises two resiliently biased, freely flooded telescoping members a first of which has a first end wall adapted to ride on a surface to be inspected and a second of which has a second end wall adapted to be connected to the probe with the probe transducer in registration with an acoustic energy port. A stylus is fixed to the second member for axial movement with the transducer toward the first end wall as the stylus enters a pit, whereby the length of an acoustic water path is related to the pit depth.
