Fish Finders & Chartplotters

Shop Garmin fish finders, GPS chartplotters, marine displays and compatible cartography. Start with the job the unit must perform—navigation, sonar, or both—then confirm the exact transducer, chart and network compatibility for your boat.

Fish finder, chartplotter or combination unit?

  • Chartplotters provide GPS navigation and marine-chart functions. Some models have no built-in sonar and need a compatible sounder module before they can display sonar.
  • Sonar-capable units use a compatible transducer to show depth, fish and structure. Traditional CHIRP, ClearVü, SideVü and live-sonar support varies by model.
  • Combination units integrate chartplotting and sonar, but a transducer may be included, optional or sold separately.

Check compatibility before ordering

Match the display to the available helm space and viewing distance, then check power requirements, connector type and networking needs. For sonar, confirm the transducer connector, frequency, mounting style, hull material and deadrise compatibility. For navigation, confirm that the selected South African or regional chart format is supported by the exact device generation; Garmin Navionics+, BlueChart g3 and third-party Navionics cards are not interchangeable on every unit.

Read the individual product specification carefully, especially where otherwise similar models are offered with or without sonar or a transducer.
