TEMPO 501 Tracker II Underground Wire Locator — 7 ft Deep, 4,000 ft Range (2026 Model)

Overview

Meet the TEMPO 501 Tracker II, a rugged underground wire locator built to help you identify buried wires and metallic conduits with confidence. The kit is designed for field use, offering a streamlined setup that brings together a transmitter and receiver in a portable package ideal for quick checks before digging, trenching, or installations.

Key capabilities at a glance

Designed to cover practical job-site needs, the 501 Locator locates buried conductors over distances up to 4,000 feet (1.2 km) and can determine depths up to 7 feet (2.2 m). It provides flexible connection options for active or dead systems, with adjustable transmitter output and receiver sensitivity to help you dial in accuracy across diverse soil and interference conditions.

• Trace Electrical lines, Communications cables, and metallic pipes using inductive detection.
• Identify dog fences, invisible fence wires, outdoor or landscape lighting cables, and even fish tapes.
• Trace Coax, Telephone, and Utility lines with a single, portable locator that adapts to existing on-site setups.

What’s in the kit

The complete portable kit includes a transmitter assembly, a receiver assembly, an inductive coupler (clamp), a built-in inductive antenna, two 8-foot test leads with heavy-duty clips, and a sturdy polyethylene case. This thoughtful bundle is designed for quick setup and reliable performance in the field.

• Transmitter and receiver provide complementary feedback to confirm a path and depth.
• Inductive clamp and built-in antenna offer versatile locating options for different site layouts.
• Test leads and clips ensure dependable connections when tracing or verifying routes.

Why it matters for field work

Efficiently tracing buried lines can save hours, reduce unnecessary digging, and help you avoid unintended encounters with buried utilities. The inductive signaling approach supports locating on active lines or dead systems, enabling you to map a path with greater confidence and fewer surprises.

Use cases and real-life scenarios

• Prepare for outdoor installations by locating and mapping wires for landscape lighting, irrigation controls, or security systems.
• Verify the route of an existing buried run, such as coax or power lines, before excavation or re-routing.
• Investigate unknown underground lines on a worksite and mark the path for safe future work.
