We investigate the use of galaxy number counts (GNC) to probe for voids. As a first step, we create a toy model of a volume of space with a random distribution of galaxies. We then create voids in this distribution at different distances and with varying widths. As a diagnostic of the voids, we plot the log of the number of galaxies brighter than a given apparent magnitude versus the apparent magnitude. The technique turns out to be very sensitive to the distance, the size, and the type of void.
