Multifunction Displays (MFDs) for boats, yachts, and sailboats can range from a few hundred dollars to several thousand, depending on size, features, and brand. Basic models start around $300, while high-end units with advanced navigation, radar capabilities, and touchscreens can exceed $3,000. When budgeting for an MFD, consider what features you truly need. If you're a casual boater, a simpler model may suffice, but serious anglers or cruisers might want to invest in a more robust system that integrates with other onboard electronics for a seamless experience.
