New in the 3D viewer: slice the measured field open with a movable cross-section, scrub the pulse to any moment, and set a full-scale person on the mat to see depth and coverage.

Every example report now includes an interactive 3D viewer of the measured field: a field dome for reach, a new topographic map for strength, and the device's real pulse.

A PEMF field does not stop at one line. It fades from the center, and two boundaries, the strong core and the usable edge, describe what you actually get.

Frequency is one of the few PEMF specs you can actually use, once you read the band name for what it is: a pulse rate, separate from strength and from the pulse edge. Here's what it tells you, what the devices we've measured actually run, and how to use it.

Rise time, fall time, and slew rate describe what a PEMF pulse does in its few microseconds. Here is what each one means, measured on a real device.

We bought a Sota Magnetic Pulser and put it on our instruments. Here is its real measured output: peak field, slew rate, field reach, and pulse rate, at each setting.

You're comparing two devices. One lists 20,000 Gauss, the other lists 800, and the first looks twenty-five times stronger. It might be. It might also be weaker. Until you know what each maker measured, the two values can't be compared at all. This month we read the public product and testing pages of PEMF makers across the industry, from high-intensity coils to low-intensity mats, and logged how each one states its field strength. There is no shared convention. Most publish a single Gauss figure without saying how it was measured. A few publish a time-averaged value. At least one publishes…

When your buyer reads the peak Gauss value on your spec sheet, they imagine that's for the entire surface of the accessory. They don't know that it's measured at one point, at one setting, directly on the accessory surface. Additional measurements let you show more of the accessory's characteristics in your documentation. A side-by-side diagram titled 'Peak Gauss alone doesn't provide the clarity needed to make an educated purchase.' On the left, under the heading 'On the spec sheet,' a gold block displays '7,000 G' as the Peak Gauss reading, called out as the highest reading at one point on…
