A slide rule is described by which the dip of reflectors can be computed rapidly and accurately for the case where instantaneous velocity can be assumed to increase linearly with depth. Values for initial velocity V 0 , rate of increase of velocity, k, and the spread distance Delta x, can be introduced into the device easily and changed at will. In conjunction with a previously described instrument, normal move-out graphs and wave front charts can be constructed quickly and precisely.
