The Garmin GPS 17N, designed primarily for use in marine applications, delivers exceptional accuracy while standing up to the harshest environment. This pole-mount GPS sensor has an integrated antenna housed in a rugged, water resistant design. The 12-channel receiver allows for continuous tracking of all visible satellites. And it's WAAS capable, which means it can provide position accuracy of less than 3 meters on average. This incredible accuracy is possible without the use of an external DGPS beacon receiver. The GPS 17N also offers excellent EMI/RFI performance for easy integration into systems that will be operated near mobile computing devices and wireless communications equipment. The 30 ft. cable is terminated in loose wires.
