The GSR 2, home biofeedback device precisely monitors your stress levels by translating tiny tension-related changes in skin pores into a rising or falling tone.

By resting two fingers on the sensing plates you learn to lower the pitch and your stress level. Cordless finger-rest sensor - with built-in-tonal feedback - automatically measures Galvanic Skin Response (GSR).
