The Ultimate Buying Guide for Fish Finder Chartplotters
Choosing the right fish finder chartplotter can change your time on the water. These devices combine two vital tools: a fish finder to see what’s below and a chartplotter to know exactly where you are. This guide helps you pick the best one for your needs.
Key Features to Look For
When shopping, focus on these main features. They decide how well the unit works.
1. Sonar Technology
- CHIRP (Compressed High-Intensity Radiated Pulse): This is the best sonar. It sends a range of frequencies. This gives you clearer images of fish and structure. Look for units offering CHIRP.
- Down Imaging and Side Imaging: Down imaging shows what is directly beneath you. Side imaging scans the water on both sides of the boat. These features give you a wider view of the underwater world.
2. Display and Screen
- Screen Size: Bigger screens are easier to read, especially when moving fast. For smaller boats, a 5-inch screen might work. Larger boats benefit from 9-inch or 12-inch displays.
- Brightness and Resolution: You need a bright screen. Direct sunlight can wash out dim displays. High resolution means sharper images for both charts and sonar.
3. GPS and Mapping Capabilities
- Built-in Maps: Most units come with basic worldwide maps. Check if the plotter includes detailed coastal or freshwater maps for your primary fishing spots.
- Transducer Type: The transducer sends and receives the sonar signal. Ensure the included transducer matches the depth and water type you usually fish in.
Important Materials and Build Quality
The materials used determine how long your unit lasts. You want something tough.
Durability and Water Resistance
- IP Rating: Look for a high Ingress Protection (IP) rating, like IPX7. This means the unit resists splashes and temporary submersion.
- Construction: Quality units use rugged, UV-resistant plastic casings. These materials handle constant sun exposure and rough boat movement well.
Factors That Improve or Reduce Quality
Some features boost performance, while others can slow you down.
Quality Boosters
- Networking Capability: If a unit can connect with radar, autopilot, or other displays (like NMEA 2000), its usefulness grows significantly.
- Processor Speed: A fast processor redraws the screen quickly. Slow redraws make it hard to track targets when the boat is moving.
Quality Reducers
- Proprietary Cables: Some brands force you to use only their specific cables. This makes repairs and upgrades harder and more expensive.
- Outdated Software: Ensure the model you buy supports the latest software updates. Old software often means missing new features or bug fixes.
User Experience and Use Cases
How easy is the device to use on the water matters a lot.
Ease of Use
Touchscreen interfaces are popular now. They allow quick zooming and menu access. However, some experienced boaters still prefer physical buttons, especially in rough conditions when gloves might be worn.
Use Cases
- Small Boat Angler: You need a compact unit with excellent CHIRP sonar for finding fish near structure. Portability is a plus.
- Coastal Cruiser: You need strong GPS, detailed navigation charts, and maybe radar integration for safety in fog or at night.
- Deep Sea Fisherman: High-power sonar and transducers capable of reaching depths over 1,000 feet are necessary.
10 Frequently Asked Questions (FAQ) about Fish Finder Chartplotters
Q: What is the main difference between a fish finder and a chartplotter?
A: A fish finder shows you underwater life and structure using sonar. A chartplotter uses GPS to show your boat’s position on detailed maps.
Q: Do I need CHIRP sonar?
A: Yes, CHIRP sonar is highly recommended. It provides much clearer separation between baitfish, game fish, and the bottom compared to older single-frequency sonar.
Q: Can I use my old transducer with a new unit?
A: Sometimes, but often no. Modern units use specific digital signals. You usually need a transducer matched to the specific brand and model of the new chartplotter.
Q: How important is screen brightness?
A: Screen brightness is very important. If the screen is not bright enough, glare from the sun makes it impossible to see your important navigation or sonar data.
Q: What does NMEA 2000 mean?
A: NMEA 2000 is a standard communication network. It lets your chartplotter share data, like engine speed or depth, with other marine electronics on your boat.
Q: Should I choose a touchscreen or buttons?
A: This is personal preference. Touchscreens offer fast access to many menus. Buttons are easier to use when the boat is bouncing or when you are wearing wet gloves.
Q: Do I have to buy extra maps?
A: Many units include good base maps. For detailed navigation in specific areas, like complex reef systems or inland lakes, you might need to purchase an upgrade card.
Q: What depth can most standard units read?
A: Most standard units work well down to about 500 to 1,000 feet. If you fish much deeper, you need a specialized, higher-powered transducer system.
Q: How do I keep the screen safe from the sun?
A: Always use the included protective cover when the unit is not in use. Sun exposure degrades the screen material over time.
Q: Is a unit with built-in GPS better than one that needs an external antenna?
A: For most recreational users, built-in GPS is fine. It keeps the installation simple. Only large vessels or those with complex metal structures might need an external antenna for better signal reception.
