Buying Guide for the Best Chartplotter
Choosing the right chartplotter for your boating needs can significantly enhance your navigation experience. A chartplotter is an essential tool that helps you plot your course, track your position, and avoid hazards while on the water. To make an informed decision, it's important to understand the key specifications and how they align with your specific needs. Here are the main specs to consider when selecting a chartplotter.Screen SizeThe screen size of a chartplotter is crucial as it determines how much information you can see at once and how easy it is to read the display. Screen sizes typically range from 5 inches to over 12 inches. Smaller screens (5-7 inches) are more compact and suitable for smaller boats or limited dashboard space. Medium screens (8-10 inches) offer a good balance between visibility and space, making them ideal for mid-sized boats. Larger screens (11 inches and above) provide the best visibility and are perfect for larger vessels or those who need to see detailed charts and multiple data inputs simultaneously. Choose a screen size that fits your boat's space and your need for visibility.
ResolutionResolution refers to the clarity and detail of the display. Higher resolution means sharper and more detailed images, which can be particularly important for reading charts and identifying features. Resolutions can range from 480 x 272 pixels in smaller, basic models to 1280 x 800 pixels or higher in premium models. If you need to see fine details and use the chartplotter in bright sunlight, opt for a higher resolution. For casual use or smaller screens, a lower resolution may suffice.
GPS ReceiverThe GPS receiver in a chartplotter determines how accurately and quickly it can pinpoint your location. A high-quality GPS receiver will provide more accurate positioning and faster updates, which is crucial for safe navigation. Some chartplotters come with built-in GPS, while others may require an external antenna. For most users, a built-in GPS with good accuracy (within a few meters) is sufficient. If you navigate in challenging environments or need the highest precision, consider a chartplotter with an advanced GPS receiver or the option to connect an external antenna.
Chart CompatibilityChart compatibility refers to the types of nautical charts the chartplotter can use. Different chartplotters support different chart formats, such as Navionics, C-MAP, or proprietary charts. It's important to choose a chartplotter that supports the charts you prefer or need for your region. Some chartplotters come with preloaded charts, while others require you to purchase them separately. Ensure the chartplotter you choose is compatible with the charts that cover your boating areas and provide the level of detail you need.
ConnectivityConnectivity options in a chartplotter can include Wi-Fi, Bluetooth, NMEA 2000, and Ethernet. These connections allow the chartplotter to communicate with other devices, such as fish finders, radar, autopilot systems, and smartphones. Wi-Fi and Bluetooth enable wireless updates and data sharing, while NMEA 2000 and Ethernet provide robust connections for integrating with other marine electronics. Consider your current and future needs for connectivity and choose a chartplotter that offers the necessary ports and wireless capabilities.
User InterfaceThe user interface (UI) of a chartplotter affects how easy it is to use. A well-designed UI with intuitive menus, touchscreens, and customizable displays can make navigation simpler and more efficient. Some chartplotters offer touchscreens, while others use buttons or a combination of both. If you prefer a more modern, smartphone-like experience, a touchscreen may be ideal. For rough conditions or when wearing gloves, physical buttons might be more practical. Choose a chartplotter with a UI that you find easy to navigate and operate.
Durability and WaterproofingDurability and waterproofing are important for ensuring your chartplotter can withstand the marine environment. Look for chartplotters with high waterproof ratings (such as IPX7 or IPX8) to ensure they can handle splashes, rain, and even brief submersion. Additionally, consider the build quality and materials used, as these will affect the chartplotter's longevity and resistance to corrosion. If you frequently boat in harsh conditions, prioritize a chartplotter with robust durability and waterproofing features.
