Buying Guide – How to Choose the Best Chartplotters for Offshore Fishing

Choosing the right chartplotter involves considering several factors to ensure you get the performance you need for safe and successful offshore trips.

Display Size and Quality

Larger displays provide better visibility of charts and sonar which is crucial when you are away from shore. Look for sunlight-readable screens with high resolution to ensure clarity under harsh conditions.

Choose a size that fits your dashboard but allows you to see all important details without straining your eyes during long trips.

Sonar Performance

Effective sonar is essential for locating fish and structure in deep water. Features like CHIRP and Side Imaging provide clearer images than traditional sonar systems.

Prioritize units with high-resolution imaging and broad frequency support to ensure you can detect fish at various depths and distances.

Mapping and Navigation

Detailed maps are vital for navigating offshore waters safely. Look for units with preloaded coastal charts or support for premium map cards.

Ensure the chartplotter supports updates so your maps remain current for accurate route planning and hazard avoidance.

Connectivity Options

Connectivity allows you to integrate the chartplotter with other devices like radar autopilots and fish finders. Check for Wi-Fi Ethernet and NMEA 2000 support.

Robust connectivity ensures your electronics work together seamlessly to provide a comprehensive view of your vessel and surroundings.

Durability and Build Quality

Offshore conditions can be tough on electronics so durability is key. Look for units rated for marine environments with resistance to salt spray and impact.

A solid build ensures your device lasts longer and performs reliably even in rough weather conditions.

Ease of Use

An intuitive interface allows you to access features quickly without distracting from fishing. Touchscreens and keypads should be easy to operate.

Test the user interface to ensure menus are logical and controls are responsive to your inputs.

Budget and Value

Set a realistic budget that balances features with cost. Sometimes paying more for better sonar or mapping pays off in productivity.

Evaluate the long-term value of features like software updates and warranties to ensure you get the most for your investment.

Frequently Asked Questions

What is the best size for an offshore chartplotter?

For offshore fishing a screen size of 9 to 12 inches is generally recommended as it provides a good balance between visibility and space. Larger 16-inch units are ideal if you have enough dashboard real estate for detailed navigation data.

Do I need a separate GPS if I have a chartplotter?

Most modern chartplotters have built-in GPS receivers so you do not need a separate unit. However some models allow you to connect external GPS antennas for improved accuracy in signal-poor areas.

What is the difference between traditional and CHIRP sonar?

CHIRP sonar sends a continuous range of frequencies while traditional sonar sends a single frequency. This results in clearer images and better target separation with CHIRP systems making them preferred for offshore fishing.

Can I use my chartplotter in freshwater?

Yes most chartplotters work in both freshwater and saltwater environments. Just ensure you select the appropriate map card or software license for the region where you plan to fish.

How do I update the maps on my chartplotter?

You can usually update maps via Wi-Fi or by connecting the unit to a computer with a map card. Check the manufacturer's app or website for detailed instructions on software and map updates.

Is a touchscreen or keypad better for offshore fishing?

Touchscreens offer intuitive control but keypads are often more reliable in wet conditions. Many units offer both allowing you to choose the input method that suits your needs best.

Do chartplotters come with fishing features?

Yes modern chartplotters include advanced fishing features like sonar imaging and structure scanning. Some also support third-party apps for temperature monitoring and fish finding analytics.

How do I protect my chartplotter from saltwater corrosion?

Rinse the unit with fresh water after use and keep it covered when not in use. Regular cleaning helps prevent corrosion and extends the life of the electronic components.
