Fishfinder and Navigation Combined

A fishfinder GPS combo incorporates a Global Positioning System (GPS), a satellite-based navigation made up of at least 24 satellites.

Each satellite transmits a signal and orbital parameters that allow devices with GPS to compute the exact location of the satellites, and then measure the distances by the amount of time it takes to receive the signal.

This translates to the receiver being able to determine the user’s location and electronically display it in the fishfinder.

Advantages of A Fishfinder GPS Combo

A fishfinder GPS combo offers anglers several advantages compared to purchasing the two units separately. Combining the two devices in one provides you the essentials for fishing and navigational needs while saving you money and simplifying your life.

You will only need to install one combined device and conveniently view the different data on one device. Having a combined fishfinder and GPS in one unit will also result in having less overall clutter in your boat.

For anglers and fishermen who fish on deep and open waters, a GPS unit is a must-have. Navigation becomes tricky in the middle of the ocean. Even for experiences fishermen and professional anglers, it may be very difficult to get back to your favorite fishing spots without a GPS unit.

When using a fishfinder GPS combo unit, not only will you be able to accurately navigate and locate great fishing spots, but you will also be able to save multiple fishing locations for future use.

With a fishfinder GPS combo, you can always head back to your precise favorite fishing spots. Some fishfinder GPS combo units include additional features that allow gathering of data about water depth and other conditions, in relation to location.

Choosing a Fishfinder GPS Combo

1. Screen Display

Because the screen of a fishfinder GPS combo displays both readings for finding fish and for navigating, of course, you would want a unit that has quality screen display.

It is important to take into consideration the size and the resolution of the screen. Go for the largest and highest resolution screen that would suit your budget. With this, you would be able to locate, navigate, mark, and read fishing spots and information on the screen.

2. Frequency

When scanning and locating objects and fishes underwater, fishfinders operate under a range of frequencies. The range of frequencies is important because it dictates the quantity of sonar waves being sent out and received. The higher the frequency, the more information will be transmitted. 

Although higher frequency provide greater details, it may fail to work in deep waters. On the other hand, lower frequencies carry further, but may yield less details on the screen.

Because of this, many advanced fish finder GPS combo units use multiple frequencies at the same time, which allows them to switch between narrow and more detailed views, and broader and more general views.

3. Power

Higher power output means better and deeper readings. Generally, fishfinders can display readings of up to 400 feet for every 100 watts. The combination of the frequency and the power of a fishfinder GPS combo unit gives a better understanding of the device’s ability.

Choosing the best fishfinder GPS combo that is right for you is a balance among your fishing needs for details, coverage (depth and width), power, and image clarity.

The Verdict

With the advancement of technology nowadays, fishfinders have been constantly upgraded and modernized with amazingly helpful features. Among the reviewed top fishfinder GPS combos, we believe that the Simrad GO7 XSE Chartplotter is currently the best in the market.

Its 7-inch multi-touch display is very easy and convenient to use because of its intuitive and familiar controls and personalized homescreen. It also has a split-screen view, which is great in simultaneously viewing information from both fishfinder and GPS.

The 2D and 3D maps and the built-in different sonars also allow real-time depth tracking and provides a holistic view of what are underwater.

With Simrad GO7 XSE, navigation becomes more precise because it updates position ten times per second. You can also mark and record waypoints, which would be very helpful in navigating back more confidently to favorite spots in the water.
