The strength of a magnet is measured in units called 'Gauss'.
All Bioflow products (excluding the Classic) measure in excess of 2000 gauss on the main magnet module. The Classic measures in excess of 1750 gauss.
The magnets in the Pulsar wristbands have a surface rating of 2000 gauss.
Studies show that idealy between 1000 to 2000 surface Gauss (max) works best.
