Garmin GPSMAP® 1623xsv Combo GPS/Fishfinder

Transform Your Boating Experience with Advanced Chartplotting and Sonar

Picture this: you're out on the water, scanning for the perfect fishing spot or navigating tricky coastal waters. The Garmin GPSMAP 1623xsv steps in as your command center, blending razor-sharp GPS charting with powerful fishfinding tools. Its 16-inch IPS display delivers crystal-clear visuals even under the harshest sunlight, while built-in sonar keeps you locked on targets below. Boat owners rave about how this unit simplifies helm setups, turning complex systems into intuitive controls.

Ultra High-Definition Sonar: See More, Catch More

Dive deeper into the water column with Ultra High-Definition SideVü and ClearVü scanning sonars. These aren't your basic echoes—these paint vivid, high-contrast images that separate fish from weeds, rocks, and drop-offs effortlessly. Pair it with 1 kW CHIRP traditional sonar for broad coverage on big-water hunts. Anglers often highlight how this clarity turns frustrating blank screens into productive outings, especially in murky bays or deep offshore runs.

For live action, connect compatible Panoptix or LiveScope transducers (sold separately) and watch baitfish school around structure in real-time. It's like having eyes underwater, giving you the edge to drop lines precisely where it counts.

Sleek Design Meets Serious Power

Slender profile with edge-to-edge glass fits seamlessly into tight dashboards or expansive consoles. The upgraded processor handles multiple data streams without lag, whether you're overlaying radar, engine data, or IP cameras. Visibility shines from any angle thanks to the IPS panel—say goodbye to squinting side-by-side with crewmates.

Seamless System Building and Integrations

Building a full marine network? This chartplotter plays nice with NMEA 2000 and 0183 setups, linking autopilots, VHF radios, AIS, and Fusion audio. Engine data from various brands, including Yamaha, flows right to your screen for at-a-glance monitoring.

Take trolling to pro levels with Force trolling motor support—steer, adjust speed, and anchor from one display. Power-Pole shallow water anchors add smart features like auto-deployment and drag alerts, while CHARGE integration optimizes battery life across banks. Digital switching via OneHelm consolidates third-party controls, reducing clutter and boosting efficiency.

Sailors' Secret Weapons

Not just for powerboaters—Garmin SailAssist brings laylines, wind roses, polar tables, and tide sliders to optimize every tack. Check true wind angles, set and drift, and race-start guidance to trim sails perfectly. It's the data-driven edge competitive sailors need without overwhelming the casual cruiser.
