A range of resistivity meters with varying power outputs and up to 10 simultaneous channels.
Single channel. 200V, 25W, 500mA. For very shallow-depth exploration.
2 channels. 400V, 100W, 1.25A. For shallow-depth exploration.
2 channels. 600V, 200W, 2.5A. For medium-depth exploration.
10 channels. 1000V, 250W, 2.5A. For deeper exploration.
