The small, hand-held and self contained GSR2 is a Galvanic Skin Response monitoring device for home biofeedback. The GSR2 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.

Features:

• Uses a 9V battery (included)
• Ergonomically shaped for a most comfortable and natural grip
• Provides tonal feedback through speaker or earphones
