If you spend much of time on water just like me, you might just need the best marine GPS. I do spend much of my time on waters. If not fishing, I am either kayaking or simply cruising through the sea with my wife. I am a huge fan of the calm sea waters, and even when they get ugly, I like being part of it as well. Having been in the navy for a better part of my youthful days, I still get those memories whenever I step into the 2007 Sea Ray Sun Deck 220 I purchased for my leisure after retiring from the navy.

When growing up, I pictured myself being a writer and even started jolting down several articles for the local newspaper. That dream seemed to have gotten lost with my recruitment into the navy. However, true to the old adage “old habits die hard,” I still create time to write on almost every topic related to sea life. Today, I just woke up in my writing mood and decided to write down a review of the best Marine GPS and Chartplotter. In this review, I will give my own understanding and experience based on a practical approach on every available marine GPS and Chartplotter.
