Spooky Coil can be used with both Spooky Central and a Spooky XM generator. The differences are itemized below.
| Characteristic | Spooky Central | XM Generator |
| Power | High | Low |
| Frequency | Fixed 100 Hz | 0 - 20 MHz |
| Amplitude | Fixed at 30V | Variable |
| Waveform | Square Wave | User Definable |
The most powerful feature of Spooky Central is plasma. PEMF coil in Spooky Central helps induce electroporation at a fixed frequency.
When PEMF coil is used with Spooky2-xm generator, the power is reduced. But the coil can be used for entrainment. This usually requires variable frequencies.
