The method used will determine whether it is a good method. Using the three and four-point method, I came up with my analysis. In general, the 4 point method provides the most accurate result. In this regard, the measurement of depth in the ground directly relates to the distance A 1 for 1 exchange is essentially taking place. In general, there are one meter of depth in the ground for every meter in separation between probes. Using the cables provided and the three point method, you are allowed a maximum separation of 10 meters which equates to a depth of 10 meters (32 feet. It measures 6.2 6 ft and 65') which are equal. The distance between them is approximately 6 meters 65 feet) Nevertheless, if you get longer cables (not supplied) you can go up to the maximum distance of 30 m It is recommended to keep a distance of 42 feet (98 feet) from each other. 42 feet)
