It's a fact that most road accidents are caused by distracted drivers and road conditions can change in the blink of an eye while the driver is looking down at something. Now you don't have to take your eyes off the road to look at your speed for even an instant when you have a handy standalone GPS speedometer The easy to read 2" LCD screen can be mounted to the windscreen in seconds with the suction cup. This keeps it right in your field of vision. The LCD screen is backlit so it is highly visible at any time of the day. It displays speed in mph or km/hr and since it determines speed using GPS (Global Positioning System) instead of a mechanical device on the vehicle itself, it is more accurate than a car's inbuilt speedometer. Being a standalone speedometer unit also means that you can use this device to measure speed in any kind of moving vehicle from a boat, to an ATV to a bike. The universal speedometer has a rechargeable battery built-in and can be recharged using a car's cigarette lighter port or a USB port. It will be a very welcome addition to any driver's toolkit and is an especially useful gift for older drivers Order one today for your husband or dad for Father's Day or his birthday 2″ Large digit display Rechargeable via USB, 5V/500mA Screen Type : LCD Screen Screen Backlit : LED Backlit Diagonal Screen Size : 2.0in Width : 67.0mm Depth : 25.0mm Speed : Km/H, MPH
