The Arc-Geo Logger is the most popular and allows you to use a metal detector to log the sound output signal from the headphone jack. Then the data can be downloaded to a PC and displayed in a grid fashion to show all target locations within the plotted area. The software ASLT is used for ground resistivity and shows the data from the logger similar to a ground resistivity grid. This is a first for a metal detector owner to log data and have a hard copy of a site for later reference. The poor man’s GPR!


The Arc-Geo Logger was designed around the TF-900 detector by Discovery and can be used with many detectors on the market today! Here is a list of detectors that has been tested so far with the Arc-Geo Logger: Whites, Garrett, Tesoro, Deepstar PI and most any detector with a headphone connection! Sense the detector is the sensor part of the unit depth, discrimination and other settings only add to the ability of the logger.
