Voltage sag

If you use an HDR one problem is voltage sag. This usually occurs when a long extension cord is in use. The hyper dimensional resonator works best at 120 volts and efficiency decreases as voltage goes down in power. Less voltage means less magnetic flux is being generated by the HDR you own. This is a problem with Steven Gibbs HDR. It is important to maintain accuracy. Lower voltage will make it mess up. Steven Gibbs rarely addresses this issue.
