What the IDC Spirit Web Does: Detects changes in polarity in the ambient air, detects EMF, detects DC MF, detects any kind of static charge, all in one web. Its flexible and weatherproof. These are a combination of the IDC Indicator and the IDC EMF Detector and are very similar to Rem Pods and the Mel-meter.These are stand alone devices however they can be used in conjunction with the 3 light frequencies/laser grids that I have incorporated into my latest 2k Series InterComm box builds. Of the 2 prototypes that I have built so far One has purple and blue and the second has blue and blue, however I can do several different color frequency combinations.
