Max intensity varies based on voltage strength (intensity level setting) and resistance/size of application coils, so you get a good choice of intensities with 4 different applicators. In all models, the waveform is a classic pulse type that is the most penetrative and strongest in nature. The controllers are solid-state-digital, no more “spark chambers” unlike most other high-intensity clinical level PEMF machines. Think of TeslaFit PEMF devices as the latest standard in high-definition audio in your city’s best cinema. All PEMF machine orders also come with one free consultation with a PEMF doctor and continued product related support via user manuals, videos, phone and email. You’ll have 30 days to try our PEMF therapy devices. All PEMF therapy devices come with a 3 year international warranty on the controller and 1 year on applicators. The desk-top PEMF machines are shipped only in the United States. The TeslaFit portable PEMF systems are shipped worldwide and have the same features as the corresponding desk-top version except that they come in a pelican case. Free shipping in United States.
