The Mas mat is a pemf mat that many practitioners use. I do not recommend this for residential use.
The MAS MAT is a pemf mat that stands alone over all the other mats. It is 17 Pounds, it has 17 coils unlike the Bemer which has 6 coils. This one is sold more to doctors but the mat must be programmed. It is not a plug and play like the Bemer, QRS and IMRS which is more for the end user. I have never sold a MAS mat to an end user. It is not user friendly as you have to manually set the frequencies up to .01 Hz up to 9999Hz. It is not for the end user is my best advice for an end user researching this mat. You also have to manually set the polarity to south or north.
The MAS mat is very powerful. The more copper it has in the coils the more gauss it can deliver. Most pemf mats with copper coils weigh about 4 pounds and have very little copper compared to the MAS pemf mat. This mat is focused more on power while just say the QRS and Imrs are focused more on frequencies, not as much focused on how much electricity they can push through the coils.
This mat is most popular among practitioners who deal with injuries, not really microcirculation where someone is going to use it for an hour at a time to slowly ramp up their voltage in their body.
I do not recommend this mat for those who are sensitive to high voltage or trying to get a home use mat. If you are a practitioner and are interested in this mat, please take my pemf quiz first to see if this is the right mat for you.
