Abstract:
1. A generally elongated instrument for measuring the depth of a hole with a first edge and a second edge, the instrument having a longitudinal axis, the instrument comprising: a first generally elongated member substantially oriented along the longitudinal axis and which is insertable in the hole, the first member comprising a portion positionable against a first surface in which the first edge of the hole is formed; a second generally elongated member substantially oriented along the longitudinal axis and which is slidably connected to the first member, the second member comprising a portion positionable against a second surface in which the second edge of the hole is formed and a sensor that generates an electronic signal that varies in relation to the distance between the first member and the second member; and an electronic display substantially oriented along and generally centered about the longitudinal axis for displaying information representative of the distance measured by the sensor.
