Buying Guide – How to Choose the Best Handheld GPS for Boating

Selecting the right handheld GPS for boating requires understanding key features that impact safety and usability on the water.

Water Resistance Rating

Water resistance is critical for marine devices. Look for ratings like IPX6 or IPX7 to ensure the unit can withstand splashes or temporary immersion.

A high water resistance rating ensures your device survives accidental drops or heavy rain without failing.

Floating Design

Some handheld GPS units are designed to float if they fall overboard. This feature prevents the loss of an expensive device during rough weather.

Always check if the device floats or requires a lanyard to secure it to your vessel.

Check if the device supports sharing location data with family or crew members via apps.

Price and Warranty

Prices vary significantly based on features. Set a budget that aligns with your needs, balancing cost with necessary safety features.

Review warranty terms carefully, especially for renewed or refurbished units, to ensure future support.

How to Use and Care for Your Handheld GPS for Boating

Before heading out, charge the battery fully and verify the map data is current. Test the device in a familiar area to ensure it functions correctly.
