The Apex HSR vs. The Apex HSR Pro

Both mats provide the same slew rate, penetration depth, and full-body coverage. Each uses three 24" x 24" cushions that combine to create a 72" full-body mat. The main difference with the Pro is the added functionality.

The Pro includes an additional channel, allowing you to connect a fourth cushion if needed. It also includes 5 programmable custom modes. This is especially useful for clinics, allowing staff to quickly switch between custom protocols for different customers.

What is a PEMF mat?

Copper coils, a controller, and a field your body registers.

PEMF mats are typically low to medium intensity PEMF therapy devices that are designed to provide full body coverage. They usually consist of coils enclosed in some sort of cushioning material. An electric current passes through the coils, generating pulsed electromagnetic fields.

The changing electromagnetic fields generate a tiny amount of electricity in our cells through cellular induction. Where targeted, localized PEMF application is designed to support specific limbs or muscle groups, full-body PEMF supports whole-body wellness. Research has shown PEMF therapy to help reduce inflammation, relieve pain, improve circulation, improve mental focus, support sleep, and more.

Spectra PEMF mats consist of three individual cushions (each with their own coil) and a controller. Frequency and power level are set on the controller, which is connected to each individual cushion via a cable. This modular design allows you to use the system in a variety of ways! Our mats are also designed for everyday, regular use; perfect for commercial environments.

What is slew rate in PEMF therapy?

Slew rate: the number that really matters

Holding a big magnet next to you doesn't do anything. A changing magnetic field, on the other hand, induces an electrical microcurrent in your cells. The faster the change, the more the microcurrent is induced.

That rate of change is called slew rate, and is often measured in Tesla/second (T/s). According to Faraday's law, T/s determines how much energy is transferred to the body's conductive tissue.

Here's what studies have shown:

Below 2 T/s

Fail to produce noticeable biological response.

Between 15-30 T/s

The therapeutic sweet spot.

Beyond 200 T/s

May be more harmful than beneficial.

Spectra PEMF mat slew rate vs other brands

How does the Spectra PEMF mat compare?

The visualizations below show how the Spectra mat's slew rate compares to popular competitors.

The comparisons below are based on more than 7,500 real measurements taken directly from PEMF mats using an accurate Hall Effect probe. That data was processed using MIT-developed software to create the 3D visualizations below, giving you a picture of what the testing actually measured.

Based on Real, Accurate Measurements

Every measurement, score, and 3D visualization is based on a rigorous testing methodology designed to produce accurate, objective, and repeatable results. Learn more about the testing process: 

The Rigorous Testing Process

3D Magnetic X-ray Plots

Measurements to create 3D PEMF Plots of intensity and slew rate come from over 7500 measurements using an accurate Hall Effect Probe. The data was put into an MIT software program to create an accurate visualization based on actual measurements. This is the first time a detailed test like this has been performed, and it provides a clear picture of the actual pulsed magnetic fields above a PEMF mat.

Statistical Methodology Used to Calculate Final Scores

These final score numbers are not just arbitrary, as many review pages use. We used a multi-method statistical analysis of 14 popular PEMF full-body mats. By combining two independent evaluations across 15 categories (30 data points in total), this analysis eliminated single-test bias and yielded a statistically robust score for each PEMF mat. The scores reveal their statistical weight compared to the industry. For example, if a mat has a score of 50%, it outperforms 50% of PEMF mats on the market (which is average, like getting a "C" grade on a bell curve). The Spectra Apex HSR final score of 99.2% means the Spectra outperforms 99.2% of the global PEMF industry (like getting an A+ grade). Scoring +2.41 standard deviations above the market average, the device crosses the statistically vital "two-sigma" threshold, meaning its massive performance advantage is a highly repeatable reality rather than a minor variance. With a near-perfect statistical correlation between the two testing methods (p < 0.0001), these data-driven results completely reject the idea that standard mats are functionally equivalent to the Spectra in either power delivery or manufacturing design.
