What You Need To Know About GPS Systems

The word GPS is simply a short form of global positioning system. It, therefore, goes without saying that marine GPS is the special kind of gear designed to operate in marine conditions.

Whether you are a fisherman or navigator, you’ll need these systems. They can help you find your way around large water bodies. Most importantly, they can help you store important fishing routes so you can maximize your fortunes with each trip made.

Talking about fortunes, the following now are the guidelines on how to maximize your fortunes when buying an affordable marine GPS system.

Different Types of Marine GPS Systems

There are many types of marine GPS systems out there in the world. Of these, the most common ones for most people are the handheld, chartplotters, and computer-connected ones.

The handheld systems are quite popular and that’s because they are easy to carry around. On the flipside, though, they tend to have screens that are quite small in size.

In that regard, the chartplotters provide you with the better option. These, however, need to be mounted on fixed surfaces e.g. on your fishing kayak.

Lastly, the computer-connected systems also exist. They are the most powerful GPS units out there in the world. They provide a great variety of detail and some are even 3D enabled. They, however, don’t come cheap.

Maps

The key thing that makes GPS systems effective is the maps they come with. So, in that case, you want to ensure that the unit you settle for comes with the preloaded maps for your target fishing spots. For instance, they should have the maps of all the great lakes within the US if that’s the country you’re planning to fish in.

Connectivity

Besides having all the right maps for the job, they should also have the capability to communicate. Ideally, this should be accomplished through Bluetooth and WiFi system. The main benefit of this connectivity is that it makes it easy to share valuable information across any two devices e.g. waypoints.

Power Source

While GPS systems are designed to be bad boys, they have to rely on battery power. So, it’s important to ensure that the one you settle for has just enough power to sustain you throughout the trips. And if in case the batteries are worn out, it’s comforting to know that a replacement can always be found.

Worth noting is that GPS systems are designed to either use disposable batteries or rechargeable ones. So, keep that in mind before ordering for a cheap marine GPS.

Which One Is The Best?

Our top favorite marine GPS system is none other than the Garmin 64st GPSMAP. We like it because it’s highly portable and interesting to carry around. What’s more? It has a dual-battery system which makes it quite reliable in terms of power.

It’s a solid, water-proof unit that you can bank on; any day. On the flipside, though, it doesn’t come cheap.

Final Thoughts 

Going to fish without your best marine GPS system is like making shots in the dark. You’re more or less going to come back home empty-handed if you don’t have a proper mapping system with you. So, don’t take chances, we hope that the guidelines above will come in handy in helping you make an informed choice.
