The state-of-the-art TW-7700 utilizes advanced digital signal processing for precision locating performance yet is extremely easy to use.

The lightweight receiver is simple 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 colume level, check the battery level, or activate an LCD backlight. Depth measurement is done at the push of a button.

The tranmitter allows the user to locate in either a conductive or inductive mode. A meter and switch make transmitter set up 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.
