Description
The lightweight, state-of-the-art TW-7700 utilizes advanced digital signal processing for precision locating performance, yet is extremely easy to use. The display is a large and easy to read LCD that gives the user all the necessary information to do the job. A digital keypad allows the user to set the volume level, check the battery level, or activate an LCD backlight. Depth measurement is done at the push of a button.
The transmitter allows the user to locate in either a conductive or inductive mode. A meter and switch make transmitter setup simple and quick.
In the Fisher tradition, the TW-7700 is affordable, tough, and simple to use, while providing maximum performance. A two-year limited warranty comes standard with the unit.
