NICKiNAV is a GPS Speedometer/Speed Control System that is operated using an android interface, replacing expensive Instrument Gauges with your Android Phone or Tablet. NICKiNAV increases your overall driving experience by maintaining pre-programable/adjustable speeds for all types of watersports. This affordable upgrade will improve overall speed control performance and is sure to impress anyone who enjoys wakeboarding, water skiing, wake surfing and more. Not only is the NICKiNAV designed to accurately maintain your desired speed, offering a more enjoyable experience for both the driver and rider, it also integrates volume control when retrieving a fallen rider. As the speed decreases, so does the level of the volume.
