The Car-O-Liner handEye for Android is a free software application compatible with the Car-O-Tronic Vision X3 wireless electronic measuring system and software. The mobile solution communicates with a PC via wireless network technology, eliminating the need to move back and forth between the vehicle and computer screen. What the software is displaying on the PC screen is visible on an Android smart phone in real time. The Android version can be downloaded through Google Play, and handEye is also available for iOS and may be downloaded from the iTunes/Apple online store.
