Your Guide to Picking the Best Marine GPS Plotter

Navigating the water safely and confidently is easier with a good marine GPS plotter. This handy device shows you where you are on a map and helps you plan your routes. Let’s dive into what makes a great GPS plotter.

1. Key Features to Look For

When you’re shopping for a marine GPS plotter, keep these important features in mind:

  • Screen Size and Brightness: You’ll want a screen that’s easy to see, even in bright sunlight. Bigger screens show more detail, but make sure it fits your boat’s console.
  • Chart Compatibility: Different plotters use different types of maps, called charts. Make sure the plotter you choose can use the charts for the waters you’ll be sailing in.
  • GPS Accuracy: The better the GPS receiver, the more precise your location will be on the map.
  • Sonar/Fishfinder Capabilities: Many plotters can also show you what’s under the water, like fish or the seabed. This is great for fishing and understanding your surroundings.
  • Connectivity: Look for plotters that can connect to other devices on your boat, like autopilot systems or radios. Wi-Fi and Bluetooth are also useful.
  • Ease of Use: A good plotter has simple menus and controls that are easy to understand, even when you’re busy steering.
  • Durability: Boats are wet and bumpy places. Your plotter needs to be waterproof and tough.

2. Important Materials

The materials used in a GPS plotter affect how well it holds up to the marine environment.

  • Waterproof Casing: Most plotters are rated for water resistance. Look for IPX ratings, which tell you how well it protects against water. A higher number means better protection.
  • Durable Screen: The screen should be made of strong material that resists scratches and glare.
  • Corrosion-Resistant Components: Saltwater can cause corrosion. Good plotters use materials that won’t rust or degrade easily.

3. Factors That Improve or Reduce Quality

Several things can make a GPS plotter better or worse.

Quality Enhancers:
  • High-Resolution Display: A clear, sharp screen makes maps easier to read.
  • Fast Processor: A quick processor means maps load faster and the plotter responds quickly to your touch.
  • Advanced Chart Features: Features like satellite imagery or 3D views can greatly improve navigation.
  • Good User Interface: An intuitive layout makes using the plotter a breeze.
Quality Reducers:
  • Poor Sunlight Readability: If you can’t see the screen in the sun, it’s hard to use.
  • Slow Performance: A laggy plotter is frustrating and can be dangerous.
  • Limited Chart Options: If you can’t get the maps you need, the plotter isn’t very useful.
  • Fragile Construction: A plotter that breaks easily won’t last long on a boat.

4. User Experience and Use Cases

How you use your boat will determine the best GPS plotter for you.

  • Cruising: For long trips, you’ll want a plotter with detailed charts, good route planning, and perhaps even weather forecasting.
  • Fishing: Anglers will benefit from sonar, fishfinder features, and the ability to mark fishing spots.
  • Day Sailing: For shorter trips, a simpler, more affordable plotter might be perfect.
  • Racing: Racers might need advanced features like wind data and the ability to connect to other performance instruments.

A good GPS plotter takes the guesswork out of boating. By considering these features, materials, and how you plan to use it, you can find the perfect tool to enhance your time on the water.
