Navigate Smarter and Fish Harder with Fishfinders, GPS & Chartplotters
Whether you're chasing bass on an inland lake or trolling for tuna offshore, having the right marine electronics on your helm can be the difference between a great day on the water and coming home empty-handed. Fishfinders, GPS units, and chartplotters have evolved from simple depth gauges into sophisticated, multi-function displays that combine sonar imaging, satellite navigation, real-time mapping, and even wireless networking — all in one rugged, waterproof unit.
What Do Fishfinders and Chartplotters Actually Do?
A fishfinder uses sonar transducer technology to send sound waves through the water column and interpret the returning echoes. This translates into a visual display of fish, baitfish schools, submerged structure, vegetation, and bottom composition. Modern units use CHIRP sonar — Compressed High-Intensity Radiated Pulse — which transmits across a range of frequencies simultaneously, producing far more detailed, high-resolution returns than traditional single-frequency sonar. Many units also incorporate Side Imaging and Down Imaging, which paint a nearly photographic picture of the underwater terrain on either side of and directly beneath the boat.
A chartplotter integrates GPS satellite positioning with digital nautical charts, allowing you to track your vessel's position, plot waypoints, mark fishing spots, and navigate safely through shallow or hazard-filled waters. Combo units — which pair a fishfinder and chartplotter in a single multi-function display — are the standard choice for most modern anglers and boaters, eliminating clutter at the helm while delivering the full suite of navigation and fish-finding capabilities.
Key Features to Consider When Shopping
- Screen Size & Resolution: Larger screens make it easier to read split-screen views. Look for full-color, high-resolution displays with strong sunlight readability.
- Sonar Technology: CHIRP delivers superior target separation. Side Imaging and Down Imaging provide a wider, more detailed underwater picture.
- Chart Compatibility: Ensure your unit supports the cartography you prefer — C-MAP, Navionics, LakeMaster, or proprietary mapping options.
- GPS Accuracy: Internal GPS antennas are convenient; external antennas can provide faster acquisition and better accuracy in some conditions.
- Networking: NMEA 2000 compatibility, Ethernet ports, and Wi-Fi/Bluetooth allow you to connect autopilots, radar, trolling motors, and other onboard electronics into a seamless system.
- Freshwater vs. Saltwater Use: Consider your primary environment — some units are optimized for inland lake fishing while others are built for offshore coastal navigation.
