1.It's good for targeting localized issues...I used a PEMF mat to speed my hubby's overall healing (and lessening of pain) after his heel surgery several years ago. It's also used a lot for sports injuries I think, for that reason.
2.The PEMF frequency and the settings are fixed within Spooky2 Central.Spooky2 PEMF Coil connected to a generator allows you to change waveforms and other settings that you can experiment with.
The PEMF coil has upper frequency limitations and produces more power (magnetic flux - guass) at lower frequencies.
