Bio Tuner BT8

Item # 41154
* Standard Delivery | Contiguous U.S.

The Sota BT8 (bio tuner, formerly brain tuner and BT7) has been helping people relax for over 20 years. Bio Tuner is an experimental, battery powered electronic instrument that delivers minute levels of relaxing energy to the body through electrodes. These micro-current energy pulses appear to stimulate and re-balance certain brain neurotransmitter chemicals such as endorphins, serotonin, dopamine, etc. that may be involved in many stress related conditions and for CES.

Some of these neurotransmitters are also thought to be linked to memory, creativity, learning, and intelligence. Compared to other relaxation programs, the Bio Tuner requires no special effort, training or exotic equipment. Most individuals describe the experience as being one of focused deep relaxation, even when high stress or anxiety have been present.

Over twenty years of research in the U.S. and Europe have demonstrated numerous benefits from electro-stimulation instruments like Bio Tuner. Furthermore, you never have to worry about any unpleasant pharmaceutical side-effects when using this remarkable product.

Bio Tuner includes a Quartz crystal frequency controller, digitally-controlled 20 minute automatic shut-off timer, 6 different Mode selections, and a Low Battery warning light. The BT8 is microchip controlled and includes a quartz crystal timer to ensure stable and precise frequencies. It also has two extra pulse output modes-an interrupted pulse (on 1 second, off 1 second, etc.) and a 111 Hz. voltage modulated pulse. Bio Tuner is microprocessor controlled and includes a crystal timer to ensure stable and precise frequencies, and outputs a modified rectilinear waveform with over 500 frequencies in each pulse.

The many reported benefits of the Bio Tuner tend to be cumulative in nature, gently unfolding over 23 weeks. 9-Volt DC Alkaline battery (included).


A push-button switch easily changes the output through each of six different pulse modes. Two of the modes contain the 7.83 Hz Schumann (Earth resonance) frequency, which is used by many for meditation. Colored led lights indicate each of the different modes.
