Buying Guide: How to Choose the Best Marine Chartplotter

Selecting the right marine chartplotter requires balancing several factors specific to your boat, budget, and fishing style. This guide walks through the key considerations our team used during testing.

Screen Size and Display Quality

Larger screens improve visibility and enable split-screen views showing sonar and charts simultaneously. However, physical constraints matter. Measure your available dash space before shopping. We found 7-inch displays work well on most fishing boats while 9-inch units suit larger helm configurations.

Sunlight readability varies significantly between models. IPS and SolarMAX display technologies consistently outperformed standard LCD panels in bright conditions. If you fish primarily during midday, prioritize display brightness specifications.

Sonar Technology: CHIRP, ClearVu, SideVu, and HyperVision

CHIRP (Compressed High-Intensity Radiated Pulse) sonar transmits continuous frequency sweeps rather than individual pulses. This produces clearer fish arches and better target separation compared to traditional sonar. Most modern chartplotters include CHIRP as standard.

ClearVu (Garmin), DownScan (Lowrance/Humminbird), and Down Imaging provide photograph-quality cross-sectional views beneath your boat. SideVu and SideScan extend imaging outward to reveal structure and fish holding near cover. HyperVision (Raymarine) pushes resolution to 1.2 megahertz for unmatched clarity.

Consider which imaging modes match your fishing style. Offshore anglers benefit more from ClearVu for locating bait and structure. Inland fishermen often prefer SideScan for searching expansive flats and weed beds.

Chart Compatibility and Coverage

Garmin units typically use Navionics+ or BlueChart g3 cards. Simrad and Lowrance favor C-MAPdiscover and Genesis Live. Raymarine develops LightHouse charts independently. Verify your intended cruising grounds fall within available coverage before purchasing.

Subscription costs vary. Navionics requires annual fees for map updates on some models. C-MAP offers lifetime updates on Discover cards. Factor ongoing subscription costs into long-term ownership expenses.

Connectivity and Networking

NMEA 2000 connectivity enables integration with engine monitoring systems, digital switching, and additional displays. This matters for Yamaha Helm Master, Mercury SmartCraft, and similar engine integration options.

Wi-Fi connectivity allows wireless data sharing between compatible units and smartphone apps. Bluetooth enables quick wireless updates and peripheral connections.

Touchscreen vs Button Controls

Touchscreen interfaces feel intuitive for users accustomed to smartphones. However, wet hands, gloves, and rough water conditions can make touch operation frustrating. Button controls provide tactile feedback and reliable operation in challenging conditions. Some users prefer button interfaces for primary navigation functions regardless of environment.

Transducer Installation and Mounting

Transducer placement affects sonar performance significantly. Transom mounts work well for most outboard applications. Through-hull transducers provide cleaner readings but require hull modification. In-hull (inside the hull) mounting works only on non-metallic hulls and reduces maximum depth capability.

Cable length matters for larger boats. Standard 20-foot cables may require extensions on cabin cruisers and larger fishing vessels. Factor installation complexity into your purchase decision.
