Even if you are highly skilled at old-school marine navigation techniques, you should still have a marine GPS system to help you stay oriented when you are sailing in open waters. Traditional navigation methods take time and are subject to human error. So, it is easy to become disoriented or find yourself in a shipping lane or other unfortunate spot if you do not have a reliable and accurate form of GPS on board your vessel.
Plus, marine navigation aids offer additional benefits, such as chartplotter GPS to track your journey and fishfinder features. If you want to catch a lot of fish, a portable fishfinder certainly makes it easier to hook the next big one. These features, among others, set your marine GPS system apart from other GPS models, like portable GPS devices designed for finding driving or cycling routes or handheld GPS devices for hiking and backcountry activities.
