Physical size is 170 x 90 x 50 mm (6.7 x 3.5 x 2 in.) and weight is 200 g (7 oz.).\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eNMEA 2000 heading sensor with fast 10 Hz vessel heading output and +\/-2 degrees heading accuracy\u003c\/li\u003e\n\u003cli\u003eRate of turn output at 10 Hz plus attitude data at 1 Hz for systems that use heel and trim information\u003c\/li\u003e\n\u003cli\u003eTransmits NMEA 2000 PGNs 127250 (vessel heading), 127251 (rate of turn), and 127257 (attitude data); receives 127258 (magnetic variation)\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 input voltage range from 9 to 16 Vdc; LEN 4 (200 mA at 9 Vdc) for network load planning\u003c\/li\u003e\n\u003cli\u003eIPX7 water resistance and a housing that is gasketed and sealed for damp locations on board\u003c\/li\u003e\n\u003cli\u003eTemperature range from -15 to 70 C for typical coastal and offshore operating conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e9-axis heading sensor\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 T-connector\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 drop cable\u003c\/li\u003e\n\u003cli\u003eMounting screws\u003c\/li\u003e\n\u003cli\u003eDocumentation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThis sensor does not need a view of the sky. Placement matters more than anything else: keep it away from strong magnets (speakers are a common culprit) and from ferrous metal that can skew the compass. A handheld compass is a quick way to sanity-check a spot before you drill.\u003c\/p\u003e\u003cp\u003eFor best results, mount it horizontally on a rigid surface and orient it so the cable faces toward the bow. If you use alternate fasteners, use stainless or brass hardware and avoid anything that shows magnetic pull when tested with a handheld compass.\u003c\/p\u003e\u003ch6\u003eCalibration and heading alignment\u003c\/h6\u003e\u003cp\u003eAfter it is on the NMEA 2000 backbone, run calibration so the sensor can learn the magnetic environment on your boat. When a compatible Garmin chartplotter is on the same network, calibration can be done through the chartplotter menus. On mixed-brand networks, basic calibration can be completed using a connected display that can show the sensor’s heading data.\u003c\/p\u003e\u003cp\u003eHeading alignment can be set automatically when a GPS source is present on the NMEA 2000 network. Some alignment steps require the boat to reach at least 6.4 km\/h (4 mph), so plan to do the final checks in open water.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis is a strong fit for boats that rely on stable heading for radar overlay, MARPA, autopilot steering, or for sailboats where consistent heading helps when the boat is heeled. It is also useful on fishing and cruising boats that spend time at low speed, where GPS course-over-ground can lag behind what the bow is actually doing.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269166133429,"sku":"QBP191285","price":649.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1299059_qbp191285.jpg?v=1771542302","url":"https:\/\/www.qualityboatparts.com\/products\/qbp191285","provider":"Quality Boat Parts","version":"1.0","type":"link"}
