The GSR2 instrument is small and simple and does the same things as the Relaxometers; it is quieter, and good for one person to use on their own, but less useful when two people want to hear it. Its size and its little earpieces make it easy to carry around and use in everyday situations at work, or flying, or playing sports, or whenever you feel you are under pressure. It has a loudspeaker, a pair of earpieces and a Frequency adjustment control. Optional accessories (illustrated) are a Probe for Temperature Feedback and the Meter which makes changes in the user's arousal visible instead of audible,
