Locating Near a Steel Fence ......14 Specifications, Warranty & Service ....15 Introduction The Magna-Trak 102 magnetic locator is a flux-gate type of magnetometer which incorporates a unique patented tech- nology that enables the factory to balance the magnetic sensing coils to a finite condition. -
Page 3: Theory Of Operation
Theory of Operation The Magna-Trak 102 locator finds ferromagnetic objects by sensing the magnetic field radiated by the object. The lo- cator contains two sensor coil assemblies that are precisely spaced and electronically balanced to achieve a near magnetic balanced operating condition. In a uniform magnetic field, such as the earth’s field, the two sensor coils maintain a magnetic... -

Page 6: Basic Operation And Description
Basic Operation and Descriptions Power On Button: Press once to activate the locator circuitry. Simultaneously, the circuitry is automatically set to the proper audio tone. Power Off Button: Press once to turn the battery power off. Volume Control: Rotate the knob to the desired audio sound level. - Page 7 Analog Bar-Graph Signal Indicator–the bar graph corresponds directly to audio frequency by expand- ing outward from the center “diamond” as the signal increases due to magnetic metals. Low Battery Indicator–Although not visible under normal conditions the LCD will display a flashing “Low Battery” warning when the batteries fall below a predetermined voltage.
- Page 8 The new Magna-Trak 102 and its “Erase” feature solves this problem by providing an Erase button; simply press this button when the interference is annoying and the metal struc- ture is electronically erased.

Page 10: Field Operation
Field Operation The recommended search position is a 45 degree angle from the earth’s surface. Scan the locator pole from side-to-side in a slow sweeping motion while walking in a uniform direction. Once the object being searched is located, pinpointing the objects location can be accomplished by holding the locator vertical and sweeping it in an “X”... -
Page 11: Signal Responses
Signal Response Below is an example of audio and LCD visual signal responses to (1) no object, (2) one small deeper metal target and (3) a second larger and shallower metal object. The LCD display in- dicates both the numeric digital and analog bar-graph response as the locator passes over the ground. -
Page 12: Typical Signal Responses
Typical Signal Responses The metal handles on the septic tank cover will provide a us- able signal to determine the location of the actual cover. Signal Response The metal handles on a septic tank cover Large metal objects may cause double signals as indicated. The center of the cover is found by sweeping the locator back and forth to create a ring pattern response. -

Typical Signal Responses Water Locations: The locator can be submerged into water with the pole sec- tion to just under the plastic case. Hold the locator in a vertical position while searching to pro- duce the best results. The joints, elbows and ends will create the strongest signals. Cast iron pipe, joints, elbows, etc. -
