Built for irrigation professionals, the Tempo 521E Wire and Valve Locator combines reliable signal tracing with rugged field-ready design. It locates buried control wires, valve solenoids and cable faults quickly so you can troubleshoot systems with confidence.

  • Accurate detection: Transmitter operates at 1750 Hz with up to 2500 mW into 1 kΩ, enabling reliable tracing of buried wires, solenoids and cable faults across typical irrigation systems.
  • Advanced noise rejection: Triple-stage filtering and adjustable output levels cut through electromagnetic interference near other utilities and decoders.
  • Depth measurement: Built-in 45° angle detector and depth mode let you estimate wire depth (triangulation accuracy typically within 10%), reducing digging errors.
  • Ergonomic, field-ready construction: Carbon-fiber-reinforced antenna, balanced receiver and lightweight transmitter minimize operator fatigue and withstand daily jobsite use.
  • Clear controls and audio: Sunlight-readable LCDs on both transmitter and receiver, headset jack, and a high-output audio option (96±3 dBA) for noisy environments.
  • Long runtime and accessories: Transmitter uses 6×D cells, receiver uses 4×AA cells with typical runtimes around 50 hours; includes ground stake, test leads and a padded carrying case.

Whether you’re locating a single valve or tracing long cable runs, the 521E delivers durable, precise performance. Backed by Tempo’s one-year limited warranty, it’s built to handle routine maintenance and demanding troubleshooting in irrigation systems.
