Extended-Range HDD Transmitters Compared: Depth, Frequencies, Power Modes, and Battery Life
An extended-range transmitter should give your crew more than a large depth number. The transmitter must work with your receiver, fit the housing, operate on a usable frequency, and last through the planned bore. A model that reaches farther in high power may also drain its battery within one shift. Another model may offer less maximum depth but provide more frequency options or longer runtime. This comparison covers current extended-range transmitters from Digital Control Incorporated, Subsite Electronics, and Underground Magnetics. It compares four factors.
