FAQs About Marine GPS

Much in the way that your car GPS helps you navigate the expansive roads and motorways, a marine GPS allows you to more effectively navigate your way around rivers, canals, oceans, and other major bodies of water where boats are allowed.

Along with mapping your surroundings, they allow you to chart courses and map out bodies of water, vegetation, obstructions, and sea life through the use of sonar.

Marine GPS devices also tend to include live weather and tide updates, wind speeds, your vessel’s speed, and can identify ideal areas for fishing.

To optimise your marine adventures and be better prepared for anything it throws at you, a marine GPS device is an absolute must for any boating enthusiast.

While handheld and fixed-mount marine GPS devices aim to cover similar functions and use cases, differences do tend to exist in their feature sets.

Handheld GPS devices are typically better suited for smaller vessels, kayaks, and jet skis. Fixed-mount devices are designed for larger vessels - fishing boats, yachts, cruise ships, etc.

Mounted GPS systems tend to have more comprehensive charting features and are designed for constant use as they’re connected to a power source. Handheld marine GPS units can be a great backup to have along with a mounted device or if you simply want some more surface-level navigation solutions.

Yes. A key function for marine GPS chartplotters is to provide nautical charts and marine maps to help users more easily navigate the ocean and other bodies of water. You can track your journey and refer to your GPS to retrace your steps.
