The BT9 is our full-featured Bio Tuner. It has six comfort modes to choose from — three stronger and three gentler, with two of them including the 7.83 Hz Schumann Earth Frequency — plus a low battery warning so you always know where you stand.
$160.00 USD
An economy version of the Bio Tuner. You still get the automatic 20-minute timer and core frequency pulsing, with just one mode instead of six, fewer accessories, and a 1-year warranty.
Not sure? Most customers choose the BT9 for the added frequency modes.
