The Garmin GPSMAP 1623 chartplotter ensures connectivity, clarity, and excellent control. The advanced MFD device supports the same user-friendly features as the GPSMAP x3 series but with a larger 16-inch HD IPS touchscreen. To the delight of fishermen, it supports the entire LiveScope and Panoptix sonar ranges. Once you’ve found your catch, you’ll stay in pace with it thanks to the support and integration of the Force trolling motor. Enjoy easy navigation with Garmin Navionics+ charts and Auto Guidance+ technology, and by upgrading to Garmin Navionics Vision+ premium charts, you’ll gain access to features such as depth shading (Auto Guidance+ is intended for planning only and does not replace safe navigation). You can connect multiple chartplotters, radars, and cameras through Garmin Marine Network for seamless vessel integration. For sailors, the chartplotter offers premium features like sailing polar data, and with Garmin SailAssist features, you can see laylines and race start line guidance, for example.
