Claims

[Scope of Claim for Utility Model Registration] (1) A rod-shaped ultrasonic underwater staff consisting of a master station and a slave station for measuring the distance between two points underwater; a calculating means for calculating the distance between the master station and the slave station based on the time from when the ultrasonic wave is emitted from the wave transmitting/receiving means until the ultrasonic wave from the slave station is received; and a display means for displaying the distance calculated by the calculation means, while the slave station has a wave transmitting/receiving means for transmitting and receiving ultrasonic waves, and a transmitting/receiving means for transmitting and receiving ultrasonic waves emitted from the master station. , and a control means for causing the wave transmitting and receiving means to emit ultrasonic waves in response to reception of the ultrasonic waves. (2) It has a cylindrical housing with a diameter that can be grasped and a length that exceeds a person's height, one end of the housing has a tapered shape, and the other end is provided with the above-mentioned wave transmitting/receiving means, 2. The ultrasonic underwater staff according to claim 1, wherein at least one of the master stations is provided with the display means at a location that is easy to see when the case is erected with the tapered portion as the bottom.
