Classic Instruments GPS Speedometer Sending Unit - SN81V

Classic Instruments GPS speed sensor. This is a basic, directional (rather than omnidirectional like the SkyDrive unit), GPS sending unit; outputting 16000 ppm or 8000ppm. It is a budget friendly time-proven GPS speed sending unit. Consider this option while the Classic Instrument's SkyDrive unit is being redesigned.
