- Real-time signal strength readout to guide fast, precise locates.
TEMPO 521E Wire And Sprinkler Valve Locator
The TEMPO 521E wire locator focuses on accurate tracing of buried wires and irrigation valves. It includes a 45-degree angle indicator to help determine depth before digging and a large LCD display for easy readability in bright daylight. The upgraded transmitter is removable to simplify operation in tight spaces.
- Accurate location of buried wires and irrigation valves.
- Depth determination using a 45-degree angle indicator.
- Sunlight-friendly LCD and removable transmitter for tight spaces.
RIDGID SeekTech SR-20 Locator
The RIDGID SeekTech SR-20 Locator supports tracing for pipes and cables across a broad frequency range from 10 Hz to 35 kHz. It features a large LCD screen that presents a graphic target and guidance arrows, helping map difficult locates. The omni-directional antenna and compact folding mast enhance portability for challenging job sites.
- Frequency range 10 Hz to 35 kHz for various locate tasks.
- Omni-directional antenna improves signal capture from all angles.
- Large LCD and folding mast for portable field use.
Buying Guide
Key purchase considerations include site type, required depth, and environmental conditions. For urban and industrial sites with ambient electrical noise, dual-frequency options and noise rejection are valuable. If you routinely work with irrigation systems, valve tracing, or narrow spaces, a model with a clear depth indicator and removable transmitter can save time. Durability and weather resistance matter for outdoor use, while kit contents and compatibility with other tools influence long-term value. A device with multi-directional tracing and robust signal strength helps map complex underground networks more efficiently.
