The 508S is a great tool for locating underground wires and dog fence wire

Tempo 508S Wire Finder. The Model 508S provides reliable results on buried cables to depths of 3 feet and lengths up to 1000 feet. The unit can even be used to determine the approximate depth of the wire before you dig. Fully adjustable transmitter output and receiver gain improve system performance and locating accuracy. Both the transmitter output and receiver are housed in a durable, molded carrying case with a quick reference operation guide on the inside of the lid.

	Product Features:
-	High Frequency Transmitter Provides Range up to 4000 Feet (1219 m) and Depths to 7 Feet (2 m).
-	The Transmitter Offers Three Methods of Connection: Direct, Inductive Coupler, or Inductive Antenna.
-	Inductive Coupler Clamps Around the Wire or Pipe for Use on Active Lines or Where Isolating the Line is not an Option.
-	Inductive Antenna is Built into the Case Housing and Allows the Transmitter to be Placed on the Ground Over the Wire Path to Radiate a Signal Down onto the Conductor.
-	32" (813 mm) Lightweight Receiver Provides Both Audible and Visual Indications of Signal Strength for Accurate Identification.
-	Transmitter Output and Receiver Sensitivity are Both Fully Adjustable for Maximum Accuracy.
-	Includes Transmitter Assembly, Receiver Assembly, Inductive Coupler (clamp), Inductive Antenna (built-in), Two 8 Foot (2.4 m) Test Leads with Heavy-Duty Alligator Clips, and a Durable Polyethylene Case.
-	Optional Headset is Available for Use in High Traffic Areas or Other Noisy Environments.
-	1 Year Warranty.

  

Lightweight and ergonomically-balanced for comfortable, low-stress operation. Microprocessor-based circuitry delivers increased accuracy - and features auto-gain control in all environments. Automatic signal boost makes it easy to trace lines, even those with very weak signals. Low battery indicator. Receiver may be used in active or passive mode. Traces 20 feet (6 m) underground and provides depth readings up to 15 feet (4.6 m). Receiver locates multiple passive frequencies with only a single switch setting - more convenient and time saving. Transmitter clamp fits conduit and pipe up to 3" trade size.

Marker-Mate™ Electronic Marker Locator is designed to locate all brands of buried, electronic markers, including the patented Tempo Omni Marker™, and Uni Marker™ sets an industry standard with the capability of detecting all seven application-based electronic marker types simultaneously (power, water, sanitary, telephone, gas, cable TV, non-potable water.) Marker-Mate™ is user-selectable for any of these marker types, or the Scan mode will locate the marker types simultaneously, and automatically determine which type has been detected. Marker-Mate™ scan mode, and its pinpoint accuracy, reduces time spent locating electronic markers. The Marker-Mate™ advanced pinpoint feature allows the user to adjust its detection threshold, making it possible to narrow the detection area to a precise location. Utilizing digital signal processor technology, the Marker-Mate™ is the most sophisticated, highest performing locator available built to operate in all weather conditions. Tempo's Marker-Mate™, Omni Marker™ and Uni Marker™ a complete solution!
