Buying Guide: How to Choose the Best Chartplotter for Your Small Boat
Choosing the right chartplotter for your small boat involves balancing several factors. Screen size, sonar capabilities, mapping options, and budget all play important roles in the decision. Let me break down the key considerations based on my experience testing these units across various boat types and fishing scenarios.
Screen Size Considerations
Screen size is the most critical factor for small boat owners with limited console space. The units in this guide range from 3.5 inches to 9 inches, and each size serves different needs. Compact screens under 5 inches work well for kayaks, canoes, and boats with extremely limited dash space. Mid-sized screens from 5 to 7 inches offer a good balance of visibility and compact footprint for most small boats. Large screens 9 inches and up provide the best visibility but require more mounting space.
Consider viewing distance when choosing screen size. If you’ll be viewing the unit from the bow or while standing, a larger screen makes a significant difference. Also think about split-screen capability, which allows you to view charts and sonar simultaneously. Split-screen is genuinely useful on 7-inch and larger displays, but challenging to read on smaller screens.
Sonar and CHIRP Capabilities
All modern chartplotters include sonar capabilities, but the type and quality vary significantly. Basic units offer traditional CHIRP sonar, which provides reliable fish arches and depth readings. Step up to ClearVü or ClearVu scanning sonar for photo-like down imaging that reveals structure and fish in incredible detail. For the most comprehensive view, look for units with SideVü or Side Imaging, which shows structure hundreds of feet to either side of your boat.
CHIRP technology has largely replaced traditional sonar, offering better target separation and clearer images. Most units in this guide use CHIRP technology, which sends multiple frequencies simultaneously for a more complete picture of the underwater environment. Higher-end units include multiple CHIRP channels for traditional, down, and side scanning.
Chart Compatibility and Mapping
Mapping capabilities vary dramatically between models. Basic fish finders with GPS may only include simple basemaps with limited detail. Mid-tier units often include Quickdraw Contours or similar mapping software that builds custom HD maps as you navigate. Premium chartplotters come preloaded with detailed coastal or inland charts from Navionics, C-MAP, or proprietary sources.
Consider your primary fishing grounds when choosing mapping options. If you mostly fish inland lakes, inland mapping coverage is essential. Coastal anglers need detailed charts showing depth contours, navigation aids, and tidal information. Some units allow you to purchase additional chart packages, so you can add coverage as needed.
Connectivity Options
Modern chartplotters offer various connectivity options to enhance functionality. Wi-Fi connectivity is increasingly common, allowing integration with smartphone apps like ActiveCaptain for software updates, chart downloads, and community content. Some units support networking between multiple chartplotters, allowing you to share sonar, waypoints, and routes.
Consider whether you need integration with other electronics. Some chartplotters connect to marine autopilot systems for automated navigation. Others integrate with trolling motors, radar, or marine VHF radios for complete boat electronics systems. For most small boat owners, basic Wi-Fi connectivity is sufficient.
Installation Considerations
Small boats present unique installation challenges. Consider whether you need a portable unit that can be removed when not in use, or a permanent installation with flush mounting. Portable units like the Striker series are ideal for kayaks, canoes, and boats without onboard electrical systems. Permanent installations offer a cleaner look but require more planning and installation effort.
Transducer placement is critical for optimal sonar performance. On small boats, finding a location with clean water flow at all speeds can be challenging. Some units include portable transducer options for temporary mounting. Consider whether you’ll mount the transducer on the transom, trolling motor, or through the hull.
Power requirements vary significantly between units. Basic fish finders draw minimal power and can run for extended periods on small batteries. Large chartplotters with bright displays and multiple sonar channels require substantial power. Ensure your boat’s electrical system can handle the demands of your chosen unit.
