1. A transmitter that is powered by a battery and the transmitter is receivable in a housing to form part of an inground tool for performing a drilling operation in a drilling environment using a drill string that extends from a drill rig to the inground tool, said transmitter comprising:
a regulator for generating a regulated voltage from a battery;
an antenna driver powered from the regulated voltage for electrically driving an antenna to emanate an electromagnetic signal for remote reception based on power consumption from the regulator;
an accelerometer for generating accelerometer readings that at least characterize a pitch orientation of the inground tool; and
a controller that monitors the power consumption and selectively limits the power consumption based on at least one power consumption threshold while continuing to drive the antenna to emanate the electromagnetic signal and for changing the power consumption threshold responsive to the drilling environment.
