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

Choosing the right chartplotter involves weighing screen size, mapping tools, and sonar clarity against your budget.

Display Size and Quality

Larger screens allow for split-view mapping and sonar which is vital offshore. Look for sunlight-readable panels that remain visible in bright glare.

Prioritize high resolution and brightness to ensure clarity during long hours.

Sonar Technology

CHIRP and side imaging provide detailed structure views. High resolution helps distinguish fish from debris clearly.

Ensure the system supports your preferred sonar mode for accuracy.

Mapping and Navigation

Look for preloaded coastal charts with depth contours. AutoChart or custom mapping helps record new spots while fishing.

Choose systems that support map updates to stay current.

Network Connectivity

NMEA 2000 or Ethernet allows networking multiple devices. Wireless sharing helps share data between helm and cabin.

Verify compatibility with other boat electronics you own.

Power Requirements

Modern units with bright displays consume more power. Plan battery capacity for extended offshore trips.

Check power specs to ensure your electrical system handles the load.

User Interface

Touchscreens offer speed but gloves may hinder use. Keypads provide reliable control in rough weather.

Select a mix that suits your operational environment.

Expansion Options

Future proofing is key. Ensure the unit accepts radar, trolling motor, or audio integrations later.

Check if third-party tools are supported officially.

Transducer Inclusion

Bundles with transducers save upfront costs. Otherwise budget for buying a compatible unit separately.

Match the transducer to your hull type and sonar needs.

How to Use and Care for Your Chartplotter for Offshore Fishing

Start by mounting the unit securely near the helm. Protect it from direct rain exposure with a cover if not using a hard enclosure.

Regularly clean the display with a soft microfiber cloth to remove salt spray. Salt buildup can corrode buttons and screens over time.

Keep your maps updated and back up waypoints to a cloud or card. This ensures you never lose your favorite fishing spots.

Frequently Asked Questions

Which chartplotter is best for deep offshore waters?

For deep waters look for models with high power sonar like CHIRP and wide side imaging ranges. Units with multi-band GPS help ensure precise navigation in open ocean areas.

Do chartplotters work without a transducer?

Most chartplotters can display maps without a transducer but will lack sonar fish finding features. Some units offer built-in sonar but external transducers provide better clarity.

Can I upgrade maps on a chartplotter?

Yes most modern units allow map updates via SD cards or Wi-Fi. This ensures you have current data for changing coastal waters and structures.

Is a 12-inch screen worth the extra cost?

A 12-inch screen offers more detail for split views and complex navigation. If budget allows it improves visibility and usability during long offshore trips.

What does AutoChart Live do?

AutoChart Live maps depth contours and vegetation in real time as you fish. This creates custom charts of uncharted waters for future trips.

How do I protect my chartplotter from saltwater?

Use a protective cover when not in use and wipe down with fresh water. Regular cleaning prevents corrosion on connectors and displays over time.

What is the difference between CHIRP and standard sonar?

CHIRP sends multiple frequencies for better target separation and clarity. Standard sonar sends one frequency making fish look more like a simple arch.

Are touchscreen chartplotters reliable offshore?

Touchscreens are reliable but can be hard to use with gloves or in rough water. Look for models that also include physical keypad controls for backup.

Final Thoughts on Choosing the Best Chartplotters for Offshore Fishing

Our top picks range from the feature-rich Humminbird XPLORE Series to the affordable Helix 5. Each offers distinct strengths for different offshore fishing needs.

Focus on display quality and sonar range to ensure you locate structure and fish consistently. Connectivity options also play a vital role in modern marine setups.

Always verify current prices and bundle availability before buying. Prices change frequently so check the latest offers to secure the best value.
