Magnetic Locators 
GA-72Cd  
 Unmatched sensitivity allows 
  you to find what you're looking for quickly, without the risk of passing over 
  your target.
  
  Our locators last 100% to 250% longer than others, making your investment a 
  solid one.
  
  Audio signal and 3-digit LCD readout
  
  85% of the Surveyor market can’t be wrong.
  
  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. 
  In fact, the Model GA-72Cd is backed by a 5-year warranty.

  The GA-72Cd Locator detects the magnetic field of iron and steel objects and 
  energized power lines. It provides 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
No. 1 Around the 
  World
  in Performance and Reliability.
  
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".
