Instead of gifting flowers this Christmas, how about gifting something that teaches someone the importance of fuel conservation? The ScanGauge II is just like an energy-monitoring device for cars, which can be mounted on the dashboard of most car models. The device shows how efficiently you’re driving, in a way helping you to improve your car’s mileage with good driving skills. The device displays fuel economy, fuel rate, battery voltage and vehicle speed. The data allows the driver to adjust his driving to get the most out of the precious drops of fuel. The device is a must for all car lovers and can be purchased from Terrapass for $159.95.371102
