Buying Guide – How to Choose the Best GPS for Sailing

Selecting the right GPS requires balancing portability, display size, and marine-specific features. Consider your sailing habits, budget, and whether you need handheld or mounted solutions.

Display Size and Visibility

Larger displays offer better map detail but take up more space. Look for sunlight-readable screens with anti-glare coatings to ensure visibility during bright days.

Choose a size that fits your cockpit space and viewing distance.

Waterproof and Durability Ratings

Marine environments are harsh so look for IPX7 or higher ratings. Floating designs are essential for handhelds to prevent loss overboard.

Ensure the device is rated for your expected exposure to rain and spray.

Chart and Map Compatibility

Some units include preloaded charts while others require SD cards. Verify that the map data covers your sailing regions.

Check for compatibility with your preferred chart provider.

Battery Life and Power Source

Long battery life is vital for extended trips. Some units use AA batteries for easy swaps while others have internal charging.

Prioritize devices that support standard batteries if you sail remotely.

Sailing Specific Features

Look for features like MOB alerts, depth data, and sailing polars. These specialized tools add significant value for performance sailors.

Ensure the unit offers the safety features you prioritize.

Connectivity and Integration

Modern units often connect to NMEA networks or smartphones. Check compatibility with your existing marine electronics or autopilot.

Integrated systems reduce clutter and improve data sharing across your boat.

Mounting and Portability

Decide between handhelds and fixed units. Handhelds offer flexibility while fixed plotters provide larger screens and stability.

Consider where you want to mount the unit before buying.

Price and Value

Prices vary widely based on features. Balance cost against the reliability and capabilities you need.

Remember that safety tools often justify higher investment.

How to Use and Care for Your GPS for Sailing

Always update your maps before heading out to ensure you have the latest coastal and depth data. Check battery levels or recharge the unit before each trip to avoid unexpected failures.

Keep the lens clean with a soft cloth to prevent scratches. Store the device in a dry case when not in use to protect it from salt and humidity.

Use the compass feature to set a fixed heading when winds are light. Regularly practice using the MOB function so you can react quickly in an emergency.

Frequently Asked Questions

Do I need a subscription for GPS charts?

Many devices come with preloaded charts that do not require subscriptions. However some advanced mapping services may have recurring fees. Check the specific model details before purchasing to confirm included content.

Can a handheld GPS replace a chartplotter?

Handhelds are excellent for safety and backup but lack large screens and engine integration. For primary navigation, especially offshore, a chartplotter is recommended for better visibility and data depth.

What is the typical battery life for these devices?

Most handhelds offer between 16 to 25 hours on standard batteries. Expedition models can last weeks in standby mode. Always carry spare batteries for extended sailing trips.

Are these devices compatible with NMEA networks?

Fixed chartplotters often support NMEA for data sharing with other boat systems. Handhelds typically connect via Bluetooth or Wi-Fi to smartphone apps.

How do I protect the device from salt damage?

Rinse the unit with fresh water after exposure to salt spray. Store it in a dry place and avoid leaving it exposed to direct sun or humidity.

What is the difference between GPS and GLONASS?

Both are satellite navigation systems. Devices supporting multiple systems like GPS and GLONASS offer better accuracy and reliability in challenging environments.

Can I install marine maps on a handheld?

Some handhelds support SD card expansion for adding detailed charts. Check if your specific model has an SD slot before attempting to load new maps.

Do these units provide depth readings?

Only units designed for marine navigation with fishfinder integration typically show depth. Standard handhelds may not support depth sensors unless paired with external equipment.
