The GCG unit is a 2 probe system, but different than other 2 probes systems on the market today. There are two modes of operation for the GCG. One is normal and the other scaled. Normal Mode: This mode is used when searching for large changes in ground anomalies like caves. Scaled Mode: This is the mode that makes the GCG stand out from other 2 probe systems! Here's how it works. The GCG takes a sample of the average ground value determine by a number of probe samples in the area. Once you are sure the data values are constant, during a sample in Normal mode the mode switch is switched to scaled. The unit now knows the background value and all readings sampled will show above and below that value! This increases the resolution of the standard 2-probe system! The GCG has a micro-controller that handles all the data. The unit was designed to be used with the logger. There is an output that connects to the logger via the cable that come with the logger. The unit also has the standard 4-probe 6-sample selection switch if you are used to using that method. The method for this unit with the logger is placing your probe in the ground at selected points in the grid with one probe back out from the center of the grid about 30 feet. You move the probes the same way you do when you log using a metal detector! If you want to use the unit alone you can by connecting a digital volt meter with a cable supplied with the GCG unit. Mark each value down and the position and later place in software to view the plot! The GCG can be used with either the Arc-Geo or Arc-Geo Mini!
