SCOUT is a tiny device that can record and analyze data about your pulse transit time, heart rate, electrical activity of the heart, oxygen saturation and temperature in less than 10 seconds. All you have to do is hold it up to your temple. You can then see the results as well as store and track the data. For this device straight out of the future, you will only pay about $150.
