Can you use more than one metal sensing probe on the Mier, Winland or Dakota vehicle detection systems?

Yes, up to two probes may be wired in series to protect two areas by wiring them in series (wire the black wire from one probe to the red wire of the other probe and then use the two remaining wires to connect to the controller.. However, there will be a reduction in sensitivity so it is often better to use two controllers or transmitters if two areas are to be protected.
