I will add that a lot of my decisions about what to use come from reading PubMed articles or Dr. Pawluk’s pages.
That is how I choose which part of my brain to put it on or whether to do Vagal Nerve Stimulation or prefrontal cortex or try to reach the hippocampus.
Those studies also help me choose when to use deep coils. I did most of the things with the M-1 and got so many results with that, but for trying to reach some parts of the brain, I need to stack coils and I ended up buying a C-5 for that and because I wanted to treat my knees and hips and the C-5 treats more sites at the same time.
The M-1 could do everything else and most of my healings I got with that.
For things like hips and knees - try to go at least 3 hours. That is based on a study where people who used it 3 hours or more were much, much more likely to see healing than those who used it shorter.
Though go shorter if you treat your brain and your eyes. That is where the TMS setting helps because it shuts off in a half hour and that prevents what happened with me where I meant to treat my eyes for 10 minutes based on a study and woke up in the morning with it still on my eyes. It didn’t hurt my eyes, but when I first took them off, the room felt so ridiculously bright that I was afraid for a few minutes. Nothing bad happened from the error, but we are supposed to be careful with our brains and our eyes.
I say that and, yes, I have treated my brain so often that I don’t think you could call me careful, but you have to start off careful with those areas and see how your brain and eyes respond.
