Criteria for Choosing the Best Handheld GPS for Boating
Choosing the best handheld GPS for boating involves several key considerations to ensure safety, reliability, and ease of navigation on the water.
Accuracy
First, consider accuracy. This is critical when navigating on water because even small errors can lead to running aground or getting lost in open waters. Look for handheld GPS units that support augmentation systems like WAAS, EGNOS, or DGPS, which improve location precision to within a few meters. High-accuracy devices are especially important in narrow channels, near docks, or when marking waypoints for fishing spots.
Durability and Waterproofing
Boating exposes devices to splashes, rain, sunlight, and accidental drops, so durability is a must. A rugged GPS with an IPX7 or higher rating will survive immersion in water and withstand harsh marine conditions. Shock-resistant casing and corrosion-resistant materials also extend the lifespan of the device, especially in saltwater environments.
