The
GA-72Cd Locators detect the magnetic field of iron and steel objects and
energized power lines. Both provide audio detection signals that peak in
frequency when the locator's tip is held directly over the target. The
GA-72Cd has the option of nulling or peaking.
Quality Is Our
Hallmark
Schonstedt's underground magnetic locators have been setting the standards
for reliability and dependability for over 30 years. They are designed to
withstand the rigors of daily on-site usage and a wide range of
environmental conditions. Model GA-72Cd is backed by a 5-year warranty.
Only two Controls
Designed for one-hand operations, the On/Off-Sensitivity and Volume
controls are located on the underside of the cover on both locators. This
provides easy access, protects the knobs and contributes to their overall
ruggedness and dependability.
The GA-72Cd also has
easy-to-read digital and bar graph which displays of signal strength and
polarity. Once you have located a target using the audio signal, the
digital readout and polarity indicators will help you to visually pinpoint
the target and, in some instances, even determine its orientation.
Signal Strength and
Polarity Indications
The GA-72Cd's audio signal and the 3-digit LCD readout will peak, and the
(+) or (-) bar graph will expand to full scale when its tip is directly
over a vertical iron pipe. One end of a horizontal target will be (+) and
the other will be (-). This difference is very significant because it
helps you to distinguish between vertical and horizontal pipes.
With the GA-72Cd you
can select any one of four sensitivity settings. The GA-72Cd's LCD bar
graph shows the selected gain and the battery status. The GA-72Cd's
headset jack can be connected to your data logger using a standard stereo
audio plug.
Choice of Two Audio
Modes
The GA-72Cd is configured initially to provide an audio signal that is
always present (Audio Output switch set to "B"). If you do not
want to hear a signal until the locator is within the detection range of a
target, you can set the Audio Output Switch to "A".
