Combination Fishfinders & Chartplotters

Combination Fishfinders integrate fishfinding sonar with chartplotter GPS, radar, VHF, and more—all on a single multi-function display (MFD). This saves space, centralizes control, and delivers more insight in real time.

These systems use active sonar to detect underwater objects and structure, while simultaneously plotting your course, communicating weather or emergencies, and providing navigation overlays.

PSI offers top brand combo units from Furuno, Garmin, Lowrance, Raymarine, Si-Tex, Simrad, and Standard Horizon—ideal for commercial vessels, sportfishing, and offshore navigation.

History and Innovation

Fishfinders have evolved since the 1950s when analog echo sounders were first adapted for marine use. By the early 2000s, integrated GPS and sonar chartplotters became common, replacing multiple standalone instruments. Today’s combo units feature advanced CHIRP sonar, radar overlays, and wireless networking.

Leading innovations include real-time scanning sonar, touchscreen MFDs with custom views, built-in Wi-Fi for remote viewing, and AI-driven fish detection. Multi-band sonar, auto-routing navigation, and 3D bathymetry maps provide deeper insight for every mission.
