Collection: GPS - Fishfinder Combos

Combining GPS chartplotting and sonar into a single unit saves space at the helm and keeps your navigation and fish-finding data on one screen. The options here range from compact 7-inch displays like the Simrad NSX 3007 and Furuno GP1871F up to 12-inch units such as the Simrad NSX 3012, so screen size relative to your helm cutout or mounting bracket is the first thing to confirm. Transducer choice matters just as much: several Simrad models are available either bundled with a transducer or as display-only units, which suits buyers who already own a compatible transducer or want to upgrade separately. Frequencies vary across the range, from traditional 50/200 and 83/200 kHz to CHIRP and Active Imaging 3-in-1 configurations, each offering different target separation and depth performance.

Furuno units like the GP1871F and TZT10X tend to appeal to serious offshore anglers who prioritize sonar power and chart detail. Garmin's ECHOMAP series, including the remanufactured 94sv listed here, pairs well with Garmin's own transducer ecosystem. Simrad's GO XSE and NSX lines offer flexible networking and can be expanded with radar packages such as the HALO20. Before buying, verify transducer connector compatibility, available power at the helm, and whether your boat's transom or through-hull setup matches the transducer style included or intended.
