The combination of fishfinders and GPS offers anglers and fishermen a good number of advantages than purchasing these two units separately. Combining these two devices in one, provides you with everything for your fishing and navigational needs. Getting a combo, you also save money, as you pay for only a singly screen, single case and single component chassis. You are also simplifying your life, because you will need to install only one unit and then you will be able to conveniently view all the needed data on one device. For finding the best fishfinder GPS combo, you can use my reviews, in which I have picked the top products in this category of fishfinders.

Benefits of Fish Finder GPS Combos

  • Course charting. With the addition of the GPS function in your fish finder you will be able to figure out your current location and chart your way to any location. Most of the combo units come preloaded with chart information of lakes, rivers and coastal areas in the U.S.
  • Save locations. Most of the fish finder GPS devices include a feature for saving waypoints. It’s really helpful for fishermen to save their favorite fishing hotspots and then easily coursing their way back to them in the future. You can save multiple locations for future use.
  • Depth finder feature. A useful feature if you are looking for specific fish and you know that it’s attracted to underwater shelves or the opposite, looks for deeper pockets of water. This feature will give you an idea of the depth around you so you can point your boat in the right direction.
  • Water temperature sensor. On some of the more advanced models you will also find a feature that displays thermoclines, which is an area where cooler and warmer waters meet. It usually identifies deeper pockets of water.

Charting Packages for Fish Finders

Most fish finder GPS combo units have the GPS antenna built-in. Though there are exceptions that have an external antenna. Also, the GPS comes with pre-loaded charting packages. Usually, you can get a memory card and extend those charts for your specific needs. The most common charting packages include the following.

  • Basemap. Just as the name suggests it features the most basic map of the United States. They do not provide any contour, depth, or other additional data. On it you can just basically distinguish water from land.
  • ContourXD. This package is found on many Humminbird fish finders. It’s a more advanced version of a basemap and features depth, contour lines, lights/markers, and interstate highways.
  • Navionics Gold. This is one of the most popular charts used on Lowrance models. It provides a multitude of useful information, which includes currents, depth contours, tides, port plans, marsh areas, and marine services information. It covers the entire continent and allows zooming in up to 3 meters.
  • BlueChart g2 Vision. It’s Garmin’s version of the Navionics. It features auto-guidance technology, using which you can just enter a waypoint and the device will automatically find the safest and fastest route in accordance with your boat size. It gives 3D view of the land, satellite images of shoreline and ports, and the underwater view.
  • Lowrance Lake Insight. This package features incredibly detailed maps. It covers 6,300 U.S. lakes, rivers and Great lakes. It also provides over 200,000 points of interest, giving you popular fishing spots. It features high definition shaded relief and detailed contour lines.

Tips for Using a Fish Finder GPS Combo

  • Contour lines. Across the chart you will find scrawled contour lines that denote depth changes. They allow you to visualize the structure such as humps, drop-offs, ledges and flats. This all is important information for a fishermen, as it helps to discern which areas hold the fish. Between contour lines there’s a certain amount of spacing. Widely spaced contour lines show a gradual decline in depth, while closely stacked together ones indicate a sharper change in depth.
  • Buoys. Charts provide different information about the buoys, such as name color, name, and interval between flashes. Being able to locate a buoy is beneficial as the buoys are often popular fishing spots.
  • Wrecks. On nautical charts you also view the depth and GPS coordinates of wrecks. Wrecks often attract fish, though not always. Some have deteriorated too much over time, while others have been sanded over completely.
  • Seabed. If you are fishing for species like bluefish that mostly feed in the upper levels of the water, knowing the bottom changes might not be that important for you. However, if you fish for benthic fish like blackfish, cod, fluke or sea bass, this can make your fishing more successful. It’s also helpful in identifying areas where the bottom nature changes from hard to soft, which is the area where fluke and stripers often patrol. If you are using a good chart, it will provide you with information on the nature of the seabed and depth.

Bottom Line

A GPS is a must have unit for any boat. If you are also a fishing enthusiast, you will also need a fish finder that will aid you in catching fish. So needing both devices, why not get them combined into one. This will save you space, money and will make it more convenient having all the needed data right at hand. If you are looking for the best fishfinder GPS combo, I have listed above some of the top products in this category. I will also be adding GPS fishfinder reviews of each of these single products with more details on each one of them.
