Construction & Excavation

Making Locating Easier for the Construction & Excavation Industry

Are you responsible for avoiding damage (hits) to buried underground utilities or need to identify unmarked private facilities? Schonstedt offers both magnetic locators and pipe and cable locators to fit every need for the Underground Construction, Installation and Excavation Contractor.

Magnetic Locators detect buried steel objects including enclosures, vaults, pipe joints, valve or curb boxes up to 18′ deep. Magnetic locators react to the outline of a ferrous metal object to pinpoint its location with precision.

We offer a choice of five models: MAGGIE (pistol grip w/audio & display), Spot (“stick” w/audio), GA-52Cx (audio), GA-72Cd (most rugged w/audio & display) and GA-92XTd (extendable w/audio & display). For over 50 years, the GA-52Cx has been the preferred choice of surveyors around the world. The ultralight-weight Spot represents the “Next Generation Stick Locator”. The GA-92XTd allows for easier portability (expands and retracts). And MAGGIE blends the best of the GA-52Cx and GA-92XTd. All are backed with a Schonstedt 7-year warranty.

Pipe & Cable Locators detect the path and depth of electrical cables, low-voltage traffic light signals and loops, fiber optic (FO) with metal shield, armor jacket or tracer-wire. Able to detect cables or metallic pipes through any road surface at a maximum depth of 20 feet. Cables can be energized or de-energized.  All Schonstedt models can detect the circuit or pipe by means of conductive (directly connected) and inductive (in-direct) modes. An Inductive Clamp is the quickest and easiest method to trace cables in hand-hold enclosures.

Combination Kits

Magnetic and Pipe & Cable Locator Kits – MPC kits combine the best of both worlds while saving time & effort — all in one convenient hard-case for limited storage areas. Consisting of an Rex LITE Pipe & Cable Locator and GA-92XTd magnetic locator, these kits detect and locate all objects described above, as well as those transmitting at 512 Hz.

The MPC-Rex Combo Kit is truly the one kit that finds it all, designed for utility locating professionals in Water • Sewer • Gas • Electric • Telecomm industries. The Kit includes a GA-92XTd Magnetic Locator and a Rex Multi-Frequency Pipe & Cable Locator and accessories. The entire system fits easily into a custom shoulder bag.


Schonstedt also offers a range of sondes (aka mini-transmitters; moles or beacons) that work with our pipe and cable locators for even greater accuracy through non-metal (clay tile, cement, transcite, HDPE, PVC) empty pipes.
