Spooky Boost v2 has a Colloidal Silver output with a current limiting resistor. This output is also suitable for safe contact mode treatments.
Research has found that less than one milliamp is the ideal current flow for successful contact mode treatments. A higher current can cause unpleasant sensations and will most likely make the treatment less effective. It can also harm the body.
The colloidal silver output from Spooky Boost v2.0 ensures the optimum current flow is maintained at all times. The user may not be able to feel the frequencies, but this does not make the treatment less effective.
