GPS Antenna GS25The Simrad GS25 GPS antenna is the ideal GPS for any navigator that requires extremely accurate and rapid vessel position and speed updates. Unlike other position-only antennas, the GS25 provides magnetic heading for accurate boat direction at any speed and for radar/chart overlay. The GS25 easily connects to any Simrad NS Series multifunction display or any NMEA 2000 network. It is fully waterproof and can be pole or surface mounted on any vessel. *Please note this product is not suitable for use with MARPA or autopilot systems which require a rate compass such as the RC42.Features:High-Speed Position UpdateRapid Signal AcquisitionConsistent Position AccuracyIntegrated Magnetic HeadingGPS, WAAS, EGNOS and MoreCompact DesignFully WaterproofNMEA 2000 ConnectivitySimrad Yachting ConstructionWhat’s in the Box?N2KEXT-15RD 15ft Network Extension CablePole Mount GS25/ZG100/POINT-1N2K-T-RD Network T-Connector Specifications:Type: AntennasBox Dimensions: 4″H x 8″W x 11″L WT: 1.55 lbsUPC: 9420064118694
