The Garmin GPSMAP 8612xsv Chartplotter gives serious anglers and sail racers a full-network helm with crisp sonar returns, detailed mapping, and fast touchscreen control in one 12-inch full HD IPS display. The wide viewing angles and superior clarity maintain sunlight readability-even with polarized sunglasses-so you can track walleye along Great Lakes structure, follow offshore temperature breaks for salmon, or monitor laylines during a regatta without losing screen detail. Built-in Garmin Navionics+ inland and coastal mapping supports confident navigation across reservoirs, rivers, and open water, while integrated sonar capabilities (transducers sold separately) let you see below and around your boat with traditional CHIRP, ClearVAoe, and SideVAoe scanning. SmartMode station controls place sonar, radar, engine data, and charts within one-touch reach, and robust networking-ANT technology, Wi-Fi, NMEA 2000, and more-lets you connect trolling motors, autopilots, radar, and additional displays into a unified marine electronics system that scales from bass boat to offshore center console. 12 in. full HD IPS touchscreen with wide viewing angles and polarized sunglass readability Built-in Garmin Navionics+ inland and coastal mapping for detailed navigation Integrated sonar support including CHIRP, ClearVAoe, and SideVAoe (transducer required) Advanced networking with SmartMode controls, ANT, Wi-Fi, and NMEA connectivity Specifications: 12 in. display size Weight: 6 lbs 11 9/10 x 8 1/2 x 3 in.
