Conventional resistivity systems require the operator to lay out a profile in an S, or snake, shape, in order to collect 3D resistivity data. With the new Switch Plus concept this is now much more efficient, with easy roll along capability. At the heart of the system is the Syscal Junior Switch 48 resistivity meter. This unit incorporates a 100W resistivity meter with 48 nodes (switches) built into the console. By adding up to three additional Switch Plus Boxes of 48 nodes each we can create a system with 192 nodes, and possible line layouts as shown below.

The 100 W power delivered by the SYSCAL Jr Switch-48 allow to obtain good signal-to-noise ratios for dipole-dipole measurements even in suburban areas.

Application

Two types of line layouts are possible, as shown below. At the left are shown eight lines of 24 electrodes each, with the system set to roll to additional lines. Standard seismic type cable is used, with a typical spacing of up to 5m between nodes, and up to 50m between lines.

Here we show the ability of the system to roll along the line, running 4 sets of 48 nodes per line. For practical ease the recommended array is a combination of in-line colinear dipole-dipole, and broadside equatorial dipole-dipole, the latter having a greater depth of investigation.
