The invention relates to a device for measuring lateral displacement of a casing in a vertical bore and includes an inclinometer probe, a cable, and a cable reel with electronics mounted in the reel hub. The probe contains two.servo-accelerometers, a microprocessor and an electrical circuit. The servo- accelerometers provide analog signals that indicate the inclination angle of the vertical bore hole. The electrical circuit converts the analog signal from each servo-accelerometers to a digital signal which is read by the micro processor. The micro processor analyses the data and transmits the digital encoded data over a twisted-pair cable to a digital display unit connected to the cable reel hub: DC power for the probe is provided by the electronics in the reel hub over the same twisted-pair cable,
