The A-7 Cable Commander detects and traces virtually any metallic conduit by electromagnetically sensing a high frequency signal that is transmitted through the cable or pipe, either by direct transmitter hookup or induction. Depth of the conductor can be measured as well.

The high frequency tone generated is displayed on a meter as well as converted to audio for simultaneous monitoring by loudspeaker.

The A-7 is easy to learn and operate with its gun-like design and light weight. Five output settings on the transmitter permit matching and mismatching to the impedance of the conductor for maximum effectiveness. The transmitter signal output is variable from 17V to 270V.

The A-7 system includes the receiver, transmitter, induction coil antenna, ground plate assembly, and foam lined carrying case.

Inductive Couplers are available as accessories to the A-7 system as are the Sewer Snooper and Mini-Snooper (for locating non-metallic pipes or ducts).
