Schonstedt’s GA 72: The professional’s choice
Building on the successful GA 52 model, Schonstedt's GA 72 magnetic locator offers enhanced signaling features for professional operators.
With two audio modes, users can monitor signal strength through either volume or tone variations, and the LCD screen displays both the polarity and relative intensity of magnetic fields.
The GA 72 offers both nulling and peaking functions and features a compact design making it easier to use in high vegetation or tight working conditions.
"I am an absolute fan of the Schonstedt. I try to get every surveyor I know to buy one. Mine has given me absolute stellar performance. I only wish all of the instruments and products I have purchased through the years for surveying actually lived up to my needs and expectations the way the Schonstedt does. Thanks again for a fine product, and for great customer service to boot!"
