Can I use 2 A9’s at the same time if using on different body parts? My SI joints get really mad if I don’t sleep w the 4x4 on them for a few days, and I’m trying to put off injections as long as possible. But there ARE other things that it is easier to treat while sleeping…like my dominant hand.
I was unsure if they would interfere with each other.
If OK on different body parts, how about the same area? Will they cancel each other out?
That should be fine. They should not interfere.


and extra nonsense to make 20 chars!
I have done this many times. I have had absolutely zero issues using multiple ICES PEMF devices concurrently on different joints.
I saw somewhere that it is not a good idea to use a cable splitter with the A9, sending signals to 2 pairs of coils for use in 2 places. I tried it and tested them all with the chip tester, with setting on high and they showed it working fine. If this is not a good idea, perhaps you can give a brief explanation? I could see not having them all close together, but if they were somewhat apart, it would be great to fully utilize the power potential. Thanks.
its OK, but the limit is the Conservation of Energy, an inviolable physical law. If you split the signal into half to go to an additional set of coils, then the energy delivered to each set of coils will be half. In addition, every electrical connector is at least slightly inefficient, so some energy is lost at each electrical connector.
What you end up with from an energetic point of view is a little bit less, spread over a larger area. If that is what you want, then it is fine.
Thank you, Bob. That is very helpful.
I was just realizing that I usually have the power on low or medium based on what I seem to read, that longer at lower intensity is often more effective. So I might increase the intensity to highest setting with the split into 2 pairs, while making sure the chip tester shows that all are putting out enough energy to register as a functioning coil. I’ll report back if I learn anything meaningful.
