In Conductive Mode, why is the signal less likely to jump to other structures?

• A. Because the operator energizes only the conductor being traced
• B. Because the transmitter power is low
• C. Because of higher frequency
• D. Because the receiver is shielded

Answer: (A)

In conductive mode, the energy is applied directly to the conductor you’re tracing. By energizing only that conductor, the current flows along its path and returns through the ground, creating a localized electromagnetic field around that line. Because the signal is tied to a single circuit, there’s much less capacitive or inductive coupling to nearby cables or structures, so the signal is less likely to jump to other structures. The other factors listed—transmitter power, frequency, or shielding of the receiver—don’t determine this localization as directly as ensuring the energy is applied to the specific conductor being traced.
