The Ultimate Buying Guide for Chartplotter Fishfinders
Choosing the right chartplotter fishfinder can make your time on the water much more successful and enjoyable. This device combines a GPS map (chartplotter) with sonar technology (fishfinder) to help you navigate and locate fish. Here is what you need to know before you buy.
1. Key Features to Look For
The best units offer a mix of navigation power and excellent fish-finding capabilities. Always check for these essential features:
Display Size and Type
- Screen Size: Bigger screens (7 inches and up) make it easier to see maps and sonar data at a glance. Small boats might use 5-inch screens, but larger vessels benefit from 9 to 12 inches.
- Brightness: Look for high-nit ratings. A bright screen is crucial for seeing clearly in direct sunlight.
Sonar Technology
- Transducer Type: The transducer sends and receives the sonar signal. Check if the unit comes bundled with a transducer or if you need to buy one separately.
- Frequency: Lower frequencies (like 50kHz) penetrate deeper water. Higher frequencies (like 200kHz or 455kHz) offer better detail in shallower water. CHIRP sonar is the best modern technology because it sweeps a range of frequencies, giving clearer images of fish arches.
Mapping and GPS
- Base Maps: Ensure the unit includes detailed, pre-loaded maps for the area you fish in most often.
- Networking: Modern units should connect easily to other marine electronics (like radar or autopilots) using NMEA 2000 or Ethernet.
2. Important Materials and Durability
Your fishfinder will face harsh conditions. The materials used directly impact its lifespan.
Casing and Build Quality
- Waterproofing: Always check the IP rating. An IPX7 rating means the unit can survive accidental immersion in water, which is a must-have.
- Screen Material: A tough, scratch-resistant glass lens protects the display better than plastic screens.
Transducer Material
Transducers are usually made of durable plastic or bronze. Bronze is generally better for in-hull mounting on larger boats but costs more.
3. Factors That Improve or Reduce Quality
Quality is not just about price; it’s about performance under stress.
Improving Quality (What to Seek Out)
- High Processor Speed: A fast processor allows the screen to refresh sonar images quickly and switch between map and sonar views without lag.
- Touchscreen Interface: Modern touchscreens often make menu navigation much faster and more intuitive than traditional button controls.
- Side Imaging/Down Imaging: These features greatly improve the quality of what you see below and to the sides of your boat, helping you identify structure.
Reducing Quality (What to Avoid)
- Low Resolution: A small number of pixels results in blurry maps and indistinct sonar returns. Low-resolution screens make it hard to differentiate between a rock pile and a school of baitfish.
- Proprietary Cables: If the unit requires expensive, specific cables for networking, it limits your upgrade path later on.
4. User Experience and Use Cases
How you plan to use the device dictates which model you should purchase.
Ease of Use
A good user interface should let you customize screen layouts easily. If you are new to this technology, look for brands known for simple, intuitive menus.
Use Cases
- Freshwater Bass Fishing: Focus on high-frequency sonar (like 455kHz or 800kHz) for detailed views of submerged logs and docks, often requiring a transom-mount transducer.
- Offshore Trolling: You need deep-penetrating sonar (like 50kHz CHIRP) and excellent GPS accuracy for marking waypoints far from shore.
- Kayaking/Small Boat: Look for portable units with built-in batteries or models that use less power, as charging options are limited.
10 Frequently Asked Questions (FAQ)
Q: What is the main difference between a chartplotter and a fishfinder?
A: The chartplotter uses GPS to show your boat’s position on digital maps. The fishfinder uses sonar to show what is under the water, like fish and bottom structure.
Q: Do I need CHIRP sonar?
A: Yes, CHIRP sonar is highly recommended. It sends out many frequencies at once, which gives you much clearer, more detailed images than older sonar types.
Q: Can I use my chartplotter fishfinder in saltwater?
A: Most modern units work well in both fresh and saltwater. However, you must ensure the transducer is rated correctly for the salinity and depth you plan to reach.
Q: How important is screen resolution?
A: Resolution is very important. Higher resolution means crisper lines on your map and clearer separation between fish and weeds on your sonar screen.
Q: What is an IPX7 rating?
A: The IPX7 rating means the unit can be submerged in up to one meter of water for 30 minutes without being damaged. This is standard protection for marine electronics.
Q: Should I buy a unit with networking capabilities?
A: Yes, if you plan to expand your electronics later. Networking (usually NMEA 2000 or Ethernet) lets different devices share data, like GPS coordinates or radar images.
Q: Does the unit come with a transducer?
A: Sometimes it does, and sometimes it does not. Always check the box contents carefully, especially on higher-end models, as you might need to buy a specialized transducer separately.
Q: How do I mount the transducer?
A: Most common mounts are transom mounts (attached to the back of the boat). Some specialized setups require an in-hull or trolling motor mount.
Q: How much battery power do these devices use?
A: Larger, brighter screens use more power. Always check the wattage draw, especially if you rely on a small battery bank on a small vessel.
Q: Can I download custom maps?
A: Many advanced chartplotters allow you to download or create your own detailed maps using data from other sources or by using built-in mapping software features.
