Choosing Your Perfect Fish Finder Chartplotter: A Buyer’s Guide
A fish finder chartplotter is an amazing tool for any boater or angler. It combines two vital functions: finding fish and showing you exactly where you are on a map. Picking the right one can make your time on the water much better. This guide helps you understand what to look for.
Key Features to Look For
These features make the biggest difference in how well your unit works.
Display Size and Resolution
- Screen Size: Bigger screens (7 inches and up) are easier to read, especially when moving fast. Small boats might only need 5 inches.
- Brightness and Clarity: Look for high-brightness screens. You need to see the display clearly even in bright sunlight. Good resolution means the map lines and fish icons look sharp.
Sonar Technology
- Traditional Sonar (2D): This is standard. It shows you depth and if fish are below.
- Down Imaging: This gives you a near-photographic view straight below the boat. It helps you identify structure like rocks or sunken logs.
- Side Imaging: This scans wide areas to the left and right of your boat. It is great for finding fish holding near banks or drop-offs.
- CHIRP Technology: CHIRP sends a continuous sweep of frequencies. This gives much clearer images and better target separation than older sonar types.
GPS and Mapping Capabilities
- Built-in Maps: Most units come with basic world maps. Check if they include detailed, pre-loaded charts for your local waters.
- GPS Accuracy: A fast-updating GPS receiver helps you mark fishing spots (waypoints) accurately and navigate safely.
- Mapping Software: Can you upload custom maps or update the existing ones easily? Some brands let you create your own high-definition contour maps.
Important Materials and Build Quality
Your unit needs to survive water, sun, and bumps. Quality construction matters.
- Waterproofing Rating: Look for an IPX7 rating or better. This means the unit can handle splashes and brief submersion.
- Screen Material: A tough, scratch-resistant screen protects the display.
- Mounting Hardware: Sturdy, corrosion-resistant mounting brackets keep the unit secure against rough waves. Plastic mounts are cheaper but metal mounts last longer.
Factors That Improve or Reduce Quality
What makes one unit better than another?
- Processing Speed (Improves Quality): Faster processors update the map and sonar readings instantly. Slow units lag, making navigation frustrating.
- Networking Ability (Improves Quality): Modern units often connect via Ethernet or NMEA 2000. This lets you share sonar data or GPS information with other displays on your boat.
- Transducer Quality (Reduces Quality if Poor): The transducer sends and receives the sonar signal. A high-quality transducer is essential for deep-water performance and clear imaging. Cheap transducers often limit the performance of an expensive head unit.
User Experience and Use Cases
How you plan to use the chartplotter dictates what you should buy.
- For Small Boats/Kayaks: You need a smaller, more portable unit with simple controls. Focus on good basic sonar and GPS.
- For Trolling/Speed Fishing: You need excellent target separation (CHIRP) and fast screen refresh rates so you see structure clearly while moving quickly.
- For Deep Sea Fishing: High power output (wattage) and lower frequency sonar are required to penetrate deep water and still get a clear return signal.
Frequently Asked Questions (FAQ)
Q: Do I need both Down Imaging and Side Imaging?
A: Down Imaging shows what is directly beneath you, which is great for vertical jigging. Side Imaging shows a wide area left and right, which helps you scan large areas quickly to locate schools of fish or structure near the bottom.
Q: What is a transducer, and why is it important?
A: The transducer is the part that sits in the water and sends out the sound waves for the fish finder. A better transducer sends clearer signals, which results in clearer pictures on your screen. It is just as important as the screen unit itself.
Q: Can I use this unit in saltwater and freshwater?
A: Yes, most modern fish finder chartplotters work fine in both environments. However, saltwater requires more power for deep penetration. Ensure the unit has the necessary depth rating for the waters you fish most often.
Q: What does “waypoint” mean?
A: A waypoint is a saved location marked on your GPS map. You can mark where you caught a big fish, a safe channel marker, or a shallow hazard so you can easily return to that exact spot later.
Q: Does this device need an internet connection to work?
A: No. The basic GPS navigation and sonar functions do not require Wi-Fi or cellular data. You only need an internet connection if you plan to download map updates or weather overlays provided by the manufacturer.
Q: How difficult is the installation process?
A: Installing the display unit is usually straightforward, involving mounting it to the dash. The hardest part is installing the transducer, which often requires drilling a small hole in the hull or using a sturdy transom mount bracket.
Q: Is it worth buying a unit with networking capabilities?
A: If you have a larger boat with multiple displays or systems (like an autopilot or radar), networking is very helpful. It allows all devices to share GPS coordinates and sonar data seamlessly.
Q: How does CHIRP sonar differ from standard sonar?
A: Standard sonar sends one fixed ping. CHIRP sends many pings across a range of frequencies. This separation makes fish targets look much more defined, making it easier to tell the difference between a bait ball and a large fish.
Q: Will my old transducer work with a new chartplotter?
A: Sometimes, but usually not. New fish finders often use proprietary plugs and require specific transducers to utilize advanced features like CHIRP or Side Imaging. Always check compatibility before buying.
Q: What is the typical lifespan of one of these units?
A: With proper care, especially protecting the screen from constant harsh sun exposure, a quality fish finder chartplotter should last between 5 and 10 years before technology advances make an upgrade necessary.
