An in-ground sprinkler serviceability apparatus that provides a debris free environment for ease of replacement of an in-ground sprinkler head. The connector includes a first compensation structure provided on an inner metalized layer of the PCB at a first stage area of the PCB, and a second compensation structure, provided at a second stage area of the PCB, for increasing compensation capacitance with increasing frequency. A tile within the set of candidate tiles may be rejected based on a rejection boundary.
