The 521E® transmitter is built for field durability and ease of use. Housed in a ruggedized body that’s completely removable from the carry case, it’s designed for the daily demands of irrigation work. A modern LCD display, shared across the receiver and transmitter, keeps readings easy to see even in direct sunlight.

Used from the controller as part of the 521E® Wire and Valve Locator system, the transmitter supports technicians in quickly and accurately finding buried wires, irrigation valve solenoids, and faults in control cables on both traditional and modern two-wire systems. Working with the system’s improved noise rejection from triple-stage filtration, it helps make tracking along other nearby utilities easier as you follow the path of the wires to the valve.
