User FAQs

To what depths do your locators find objects?

It all depends on the size and material of the object, but some examples are:

  • Magnetic Locators:
    • Survey marker up to 9 feet
    • 1-1/4" PK nail up to 12 inches
    • 4" Cast-Iron pipe up to 10 feet
    • Well casting up to 18 feet
    • Manhole cover up to 10 feet

  • Pipe & Cable Locators:
    • Buried utilities up to 20 feet maximum
Does your Pipe and Cable Locator work on Plastic Pipes?

Yes, if the pipe is fitted with a tracer wire or a sonde (a miniature transmitter) can be inserted inside the pipe.

Will your magnetic locators find old coins, brass, gold and such?

No, our magnetic locators will only locate ferromagnetic metals (i.e. iron, steel). Coins, gold and brass do not contain ferromagnetic materials.

What are the differences among the GA-72Cd, GA-52Cx, GA-92XT and GA-72Cd?

The GA-52Cx is an easy to use, reliable, magnetic locator. The GA-72Cd is basically the same as the GA-52Cx but has an LCD meter display reflecting the relative signal strength and polarity of the magnetic field detected. The GA-92XT is a portable, retractable version of the GA-72Cd, providing one-handed operation and easily removable battery.

What is the difference between metal detectors and magnetic locators?

Magnetic locators find objects with ferrous or iron content. They do not react to other metals such as copper, brass, or aluminum, as metal detectors do. Therefore they are less subject to interference from surface debris. Magnetic locators work deeper, measuring a magnetic field originating from the buried target, whereas a metal detector can only detect shallow objects, typically 9 to 12" inches maximum.

How accurate is the depth reading on a pipe & cable locator?

Depth accuracy varies, as it is dependent on the method of connection to the target utility, the operating frequency, the placement of the ground stake, and the presence of other nearby utilities. As a general rule the conductive mode, lower frequencies, and less congested areas yield more accurate depth measurements. Always interpret the depth measurement as an approximate measurement and proceed with caution before digging to that depth.

What frequency should I use?

If you will be locating various types of utilities (power, water, sewer, etc.), or will be working on various types of soil (clay, sand, very wet, very dry, etc.), then you will most likely need to use different frequencies. In that case a multiple frequency locator is the best choice. Otherwise a single frequency locator may be sufficient. Lower frequencies travel longer distances and are less likely to �jump� to adjacent utilities, but don�t do well on poor conductors. Higher frequencies do better on poor conductors, but will travel shorter distances and have a tendency to jump to adjacent utilities. Always start with the lowest frequency possible and go up if necessary.

How easy are your pipe & cable locators to use?

Although our locators are user-friendly and simple to operate, learning the locating techniques and tricks of the trade require some basic training. Our manuals and training video are great sources of information to achieve that training. In addition, factory support is always one phone call away. Over time, experience will provide the best advantage in the use of your locator.

Repair Department FAQs

Do I need a "Return Number" before sending in my repair?

No you do not need a return number. Just fill out the repair form (download it here), print and enclose with your unit.

What is the repair warranty on Schonstedt locators?

Repair warranties are for six months. If your repaired locator fails for any reason during that time, Schonstedt will repair it at no charge to you.

How long does it take to have my locator repaired?

We will have your locator repaired and on its way back to you within 48 hours from receipt of your approval to Schonstedt for the GA-52Cx, GA-72Cd, GA-52B and GA-52C and within 72 hours from receipt of your approval to Schonstedt for the MAC-51B, MAC-51Bx, Tracemaster and XTPC. GA-52 locators are usually turned around within 1 week of your approval to Schonstedt.

How much does it cost to have my locator repaired at Schonstedt?

Our standard minimum repair charge for the GA-52Cx and the GA-72Cd is $290.00, older GA models-$320 MAC-51Bx -$340.00, and MAC-51B-$400. These prices include a new base and tube, can/cover assembly, tuning, aligning and calibration to its original manufactured specifications. These locators are returned to the customer looking and functioning like brand new. For the Tracemaster and XTPC we will provide an estimate for the repair within 24 hours of receiving it.

Is the trade in program still available?

Yes, you may contact Schonstedt or any Authorized Schonstedt Dealer and we will be glad to assist you.

Can I get my older locator models such as the GA-22, GA-32, GA-52 and GA-72Cv repaired at Schonstedt?

We do still repair some GA-52, 52B, 52C, and 72CV locators. We have most of the mechanical parts (switches, pots, battery boxes, etc) for them but do not have any of the electronics. In this case we would be happy to offer you a trade-in toward the purchase of a new Schonstedt locator.

How do I find my instrument's serial number?

If your unit is a GA series (not including the GA-92 series) or a MAC series, your serial number will be located beside the batteries (you will need to remove the cover of your unit to access the batteries). On older GA series units the serial number will be stamped in white ink on the side of the battery box. MAC series units also have the serial number on the side of the black transmitter box which is located inside the lid of the orange carrying case.

If you unit is a GA-92 series, XTpc series or XT512, the serial number is located on the left side of the unit while holding the receiver in your hand. If your unit is an XTpc series, the transmitter also has the serial number located on the side end opposite the connector side end.

If your unit is a TraceMaster the serial number is located at the top of the panel on the back of the receiver above the instructions and also on the outside of the transmitter case (lower right corner).
