How Does Rex Stack Up?

A new slim and ultralight transmitter was designed specifically for Rex. Its thin and sleek profile combines with a retractable receiver to make Rex the most user-friendly and portable pipe & cable locator on the market. And best of all, Rex is a multi-frequency locator with a price tag comparable to single-frequency locators.

Rex pipe and cable locator is lighter than other locators on the market!
