Detailed Sedona Pro Comparison Analysis
Based on the 13 critical parameters from our comprehensive PEMF buyers guide
Evaluation Criteria
Science-backed parameters that determine PEMF effectiveness
Spectra Apex HSR
Research-optimized PEMF system with 24 T/s slew rate
Recommended Choice
Sedona Pro
Medium Intensity, but poorly performing low slew rate signal
Less Effective
#1
Research-Proven Slew Rates
The most critical PEMF parameter, which determines energy transfer. Research proves a range between 10-30 T/s is optimal, but you need at least 2.5 T/s.

Sedona Pro
Poor
0.4 (surface) · 0.01 (5 inches up)

#2
Optimal Rise Time
(80-300 us)
Research shows you want a rise time between 80–300 µs for optimal induction and cellular response.
Spectra Apex HSR
Excellent
100 µs (microseconds)
Sedona Pro
Poor
7 ms (millisecond)
#3
Full Body Coverage
(coil area)
Coils are the second most important spec of a PEMF. The area of the average person is around 750 in², so you want a device with a large area to cover.
Spectra Apex HSR
Excellent
990 in²
Total Coil Area
Sedona Pro
Poor
172 in²
Total Coil Area
#4
Full Body Penetration (penetration depth)
The 2nd aspect that coils dictate is penetration depth. Because the average person is 7-12 thick, you need a device with coils that penetrate.
Spectra Apex HSR
Excellent
7.46 inches
Penetration Depth
Sedona Pro
Poor
0.75 inches
Penetration Depth
#5
Optimal Intensity Range
A meta-analysis of 3249 PEMF
studies show Medium intensity (1-10mT = 10-100 Gauss) is most research used & effective intensity for healing & regeneration.
Spectra Apex HSR
Excellent
2.4 mT = 24 Gauss

Sedona Pro
Excellent
2.5 mT= 25 Gauss

#6
Frequency (brain entrainment & programmability)
A PEMF device should
have quality brain entrainment fast start programs, and 1-100 Hz programmability to match research. Also, it should be easy to use.
Spectra Apex HSR
Excellent
0-100 Hz Programable
4 Brain Entrainment*
Sedona Pro
Good

#7
Broad Spectral Content
The spectral content or bandwidth of a PEMF device is the range of frequencies the signal contains. You want a wide spectrum which acts like an energetic multivitamin.
Spectra Apex HSR
Excellent
20-16,000 Hz
Broad Spectral Content
Sedona Pro
Good
20-6,000 Hz

#8
True PEMF vs Multitherapy Mats
Genuine PEMF system vs cheap
gemstone mats with ineffective add-ons. These are the worst examples of PEMF. One manufacturer in China makes these for 300 companies.
Spectra Apex HSR
Excellent
Purpose Built PEMF w/ Proper Signal Generation.
Sedona Pro
Good
Quality European PEMF Device.
#9
Full Body Mat and Local Applicators
Having a well-made full body
mat & proper local applicators are essential. Make sure the mat is large enough & the local applicators have different sizes & a Helmholz option.
Spectra Apex HSR
Excellent
Sectional & versatile w/FIR.
Good Local w/ Helmholtz.
Sedona Pro
OK
Heavy/bulky mat & local. Comfort just OK.
#10
Price and Value Proposition
Best value/dollar - not cheapest, but optimal price-to-performance ratio. Examination of the PEMF market reveals numerous ultra-cheap(and ineffective options (i.e., Chinese gemstone mats).

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.
