Buying Guide: Choosing the Right Chartplotter for Your Small Boat

Selecting the best chartplotters for small boats requires understanding your specific needs and how different features translate to real-world performance on the water. After testing multiple units across various boat sizes and applications, I’ve identified the key factors that should guide your decision-making process.

Screen Size Considerations

Screen size directly impacts usability and should match both your boat’s console space and typical viewing distance. For boats under 16 feet, 5-inch displays provide adequate visibility when mounted close to the helm. Boats in the 16-20 foot range work well with 7-inch screens that balance detail with compact footprint. Larger boats 20 feet and above can accommodate 9-inch or larger displays that support comfortable split-screen viewing.

Keep in mind that screen size affects more than just visibility. Larger screens consume more power, cost significantly more, and may not fit compact console layouts. Measure your available dash space carefully before purchasing, remembering to account for the mounting bracket and any protective covers.

Touchscreen vs. Button Interface

The choice between touchscreen and button interfaces involves trading convenience for reliability. Touchscreens provide intuitive operation and quick access to features through menu systems, but they become frustrating to use with wet hands or in rough water when steady contact is difficult. Keyed interfaces with physical buttons deliver reliable operation in all conditions but require learning menu navigation patterns.

Many modern units, including Garmin’s keyed-assist models, offer hybrid designs that combine touchscreen convenience with critical physical buttons. This approach provides the best of both worlds for small boat operators who encounter varied conditions. Consider how and where you typically boat when choosing between interface types.

Transducer Compatibility

The transducer is arguably more important than the display unit itself, as it determines the quality of sonar returns. CHIRP technology has largely replaced traditional single-frequency sonar, providing better target separation and bottom detail. Transducer type should match your fishing style: transom-mount for most small boats, through-hull for larger vessels, and trolling motor-mount for bow-mounted installations.

Consider transducer cable length when planning your installation. Many small boats require cable extensions to reach from the transom to the console. Transducer material also matters: plastic transducers work for most aluminum and wood hulls, while bronze or stainless steel is required for through-hull installations on fiberglass boats.

Chart Options and Coverage

Chart quality varies significantly between manufacturers and coverage areas. Garmin units typically include Navionics data, while Lowrance and Simrad favor C-MAP products. Humminbird uses their own mapping system but offers compatibility with LakeMaster for inland applications. Consider your primary boating area when choosing chart coverage.

Coastal anglers should prioritize detailed nearshore charts with navigation aids, depth contours, and tide information. Freshwater fishermen need inland lake coverage with depth contours and shoreline features. Many units require additional map card purchases for complete coverage, so factor this cost into your budget when comparing models.

Small Boat Mounting Solutions

Mounting options become critical on small boats with limited console space. Bail mounts provide quick removal for security and are ideal for boats stored on trailers. Flush mounts create a clean appearance but require cutting dashboard space and make unit removal more difficult. Tilt mounts allow angle adjustment for optimal viewing but may be less stable in rough water.

Consider RAM mounting systems for portable installations on boats without dedicated console space. These adjustable mounts allow temporary placement and removal, making them popular for kayaks, jon boats, and other small craft. Whatever mounting system you choose, ensure it provides stable viewing and protects the unit from impact and vibration.

Budget Tiers Explained

Chartplotters generally fall into three price categories, each suited to different needs and budgets. Budget units under $400 provide essential GPS and basic sonar functionality, perfect for casual boaters and those new to electronics. Mid-range units from $400-800 offer improved screens, better sonar, and more detailed maps, suiting most small boat applications. Premium units above $800 deliver large screens, advanced imaging, and networking capability for serious anglers.

When determining your budget, consider total cost including installation accessories, additional map cards, and transducer upgrades if needed. Remember that spending slightly more initially often provides better value than upgrading piecemeal later, as feature sets and compatibility improve significantly at each price tier.
