Claim Text:
1. A transmitter that is powered by a battery and is receivable in each one of a plurality of different housings each of which housings is characterized by a different housing design and each of which forms part of an inground tool for performing an inground operation in which a drill string extends from a drill rig to the inground tool, said transmitter comprising: a regulator for generating a regulated voltage from said 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; 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, when the transmitter is installed in one of the plurality of housings where the transmitter would otherwise exhibit a different power consumption that exceeds the power consumption threshold when so installed based on each housing design exhibiting a different housing-attributable signal attenuation of the electromagnetic signal.
