Limitations of Handheld Marine GPS Units
While many handheld GPS units offer a wide range of features and benefits, they do have some limitations. These include:
- Screen Size: Due to their compact size, the screens on portable marine GPS units tend to be smaller. This can make it challenging to view detailed maps or charts.
- Battery Life: This is another concern, as the compact size of these units means they have smaller batteries. Heavy usage or extended trips may require extra batteries or a power source.
- Accuracy: While portable marine GPS devices are generally accurate, their precision can be affected by atmospheric conditions, satellite visibility, and obstructions.
Despite these limitations, handheld marine GPS units remain an essential tool for any water-based activity.
Now, let’s see what you should look for before buying.
Key Features to Look for in a Handheld Marine GPS Unit
When choosing a handheld marine GPS unit, especially from Garmin devices, there are several key features to consider. These include:
Durability and Waterproofing
When navigating marine environments, your GPS unit will inevitably be exposed to harsh conditions, such as saltwater and physical shocks. As such, durability becomes a critical factor in ensuring the longevity of your device.
Furthermore, given that water-based activities inherently involve the risk of getting wet, your marine GPS handheld must be waterproof. This not only protects the device from potential water damage but also guarantees consistent performance, regardless of weather conditions or accidental drops in the water.
Accuracy and Signal Strength
The primary function of a GPS unit is to provide accurate location data. As such, it’s essential to look for units with high accuracy ratings. Additionally, the signal strength of your device is crucial, as this affects its ability to receive satellite signals in real-time. A digital compass integrated into the GPS can further enhance navigational accuracy.
High Sensitivity GPS Receiver
A high-sensitivity GPS receiver is a crucial feature when choosing a handheld GPS unit. This type of receiver is designed to pick up GPS signals more efficiently and effectively, even in challenging environments such as vast bodies of water like the ocean, where signal obstruction is minimal.
Battery Life and Power Options
Battery life is a crucial consideration for handheld GPS devices, especially when you are out in the water for extended periods. Units with longer lasting batteries ensure continuous operation and reduce the need for frequent recharging or battery replacement. Some GPS units even come with a USB port to facilitate versatile charging.
Power options are another factor to consider; some units can be charged through a standard USB port, AC power, DC power, or even solar power. A unit with multiple power options provides added flexibility, particularly in situations where one power source may not be available.
Additionally, a USB port for charging and data transfer can be vital,
Map and Chart Compatibility
Having the ability to view maps and charts on your GPS unit is vital, particularly when navigating unfamiliar waters. It’s essential to ensure compatibility with electronic marine charts or maps from reputable brands like Navionics or C-MAP. Some advanced units also have a worldwide basemap for broader navigational contexts.

Ease of Use and Readability
When selecting a handheld GPS unit, it’s essential to consider its ease of use and readability. The unit should have a user-friendly interface, touchscreen control, and convenient access to frequently used features. Moreover, it should provide smart notifications, linking to cell phones for seamless connectivity on the go.
Additionally, it is paramount that the display possesses optimal clarity and effortless legibility, regardless of whether it is subjected to intense sunlight or dimly lit environments. Consider devices with backlit or LED screens for better visibility. These factors will ensure that you can operate the device successfully and access vital information promptly when on the water.
For an added layer of safety during your marine activities, consider equipping yourself with one of the best personal locator beacons fitted with a barometric altimeter.
