1. An apparatus for customizing a telemetry system of a horizontal directional drilling system based on region specific parameters, said horizontal directional drilling system including a drill rig and an inground tool that is movable by the drill rig along an underground borepath, said apparatus comprising:
a portable locator for monitoring the position and/or orientation of the inground tool on the borepath and configured at least to transmit a telemetry signal;
a geographic database that provides the region specific parameters for the telemetry signal;
an arrangement for correlating a current location of the system with the geographic database to identify at least one local requirement for the telemetry signal; and a controller for setting the telemetry signal to conform to the local requirement.
