Magnetic Locator GA-92XTi & GA-92XTd

A Magnetic Locator that will single handedly
change the way you work in the field.

* One hand operation
* Operates in both retracted and extended modes
* Fingertip control of volume and sensitivity
* Quick change battery compartment
* Battery indicator on both models

…and best of all, it’s a SCHONSTEDT Rugged, reliable and a 7-year warranty



The locator that's always by your side, whenever you need it. You've never seen a Magnetic Locator like the XT, and once you use it, you'll never use another. When we asked our most demanding customers what they look for in a Magnetic Locator, they told us:

Accuracy Reliability Ease of Use

Fifteen months of research, design, and testing has produced the new Schonstedt XT, the most portable Magnetic Locator ever made. One hand operation makes finding faster, providing both audio and visual (XTd model) indication of ferrous objects up to 16 feet underground. And the new XT follows the Schonstedt tradition of ruggedness and reliability. So go ahead, make your move to the new Schonstedt GA-92XT.


Two models to choose from

XTd Model faceplate XTI Model faceplate

XTd Model
with LCD gain,
battery and signal strength/polarity display

XTi Model
with LCD gain and
battery display



Detect the magnetic fields of all ferromagnetic objects property markers, manholes, septic tanks, well casings, valve boxes, cast iron pipes, steel drums, unexploded ordnance up to sixteen feet below the surface.

When you have your hands full on the job site, carry the XT on your hip. You're a highly trained, experienced professional but carrying heavy tools is still part of the job. When a new product comes on the market that allows you to lessen your load and increase productivity, it deserves some attention.

Locating Tips: Magnetic

Magnetic Locators and Circuits
Magnetic locators such as the GA-52Cx and GA-72Cd can be used to determine if a circuit is active, such as an automobile rear window defogger grid, or a radiant heat panel. Set the sensitivity of the locator on high, and place the instrument sensor (the tip) near the window grid, ceiling panel, etc. Listen for a change in the output tone when the circuit is activated by its on/off control.

Searching Near a Fence
Searching in the vicinity of a chain link fence requires a reduced sensitivity setting and also some control over the orientation of the locator. As illustrated in Figure 13, position the locator horizontally, with its long axis perpendicular to the fence. This ensures that the upper sensor is kept away from the fence.

Perform the search by slowly moving the locator forward along the fence while also moving it in to the right and to the left. This technique allows you to search an area several feet wide as you move forward. Listen for an abrupt drop in the signal, (as shown by the null in Figure 14.) that will occur when the lower sensor, located 1-5/8 inches from the end of the locator, is directly over the stake. Any variation in the position of the locator will produce an abrupt rise in the frequency of the signal.

Energized Power Lines
A burbling sound on the GA-52Cx or GA-72Cd indicates the presence of an energized power line.

Determining Target Depth by Triangulation with the MAC-51Bx
The receiver can be used for the traditional triangulation method to determine the approximate depth of a target as illustrated in below. However, when using this method it is necessary to take into account the fact that the center of the cable-sensor is located 11 inches up the receiver tube from the black tip. When the position of the target has been determined by the null, mark the spot (#1) on the ground. Hold the receiver tip on the ground at this spot, slant the instrument at a 45o angle and slowly move directly back, to one side, from the target until a second null is obtained. Now mark a spot (#2) on the ground that is directly below a point 11 inches up the receiver tube from the black tip. Measure the distance between spot #1 and spot #2. This measurement indicates the approximate depth of the target.

NOTE
You should always take a depth reading on both sides of the line. If the measured distances between spots #1 and #2 on both sides of the line are not the same, there is a good chance that a nearby line is causing the two measurements to be different. Move further along the line and repeat the depth reading procedure until the measurements are the same on both sides of the line. Once two very similar measurements are obtained, the calculated depth of the cable will always be within 4 to 6 inches of its actual depth.

GA-72Cd Audio Response
Tired of the continuous tone of the locator? Remove the cover and move the slide switch to the other position. The locator sound will now change in volume as the presence of the target becomes stronger (instead of changing frequency).
