Things To Consider When Buying a Fish Finder


Not all fish finders work at the same frequencies. Some work in just one frequency, while others work in multiple frequencies.

Most fish finders operate only in just one frequency. They detect the presence of a specific type of fish and don’t have many capabilities for detecting other types of fish.

The most advanced models will have two or more frequencies, allowing them to cover a broader range. This also allows the user to look for other fish species.

The breakthrough of CHIRP technology allows you to scan a broader water area and interpret individual signal returns. This results in more detail in a produced sonar image, allowing you to scan larger bodies of water.

Different frequencies can be used to scan different depths of water. The lower frequencies, such as 50kHz and 83kHz, are good at scanning shallow waters. The higher frequencies, such as 192kHz and 200kHz, are better at scanning deep waters.

Opting for a GPS fish finder with dual-frequency capability will allow you to see more detailed information on the screen. This determines the location and size of the fish.


Most fish finders vary in split-screen sizes. Larger screens will not only reduce the amount of time it takes to read information, but they will also be easier to use.

Furthermore, you want to consider how much power the display will use. A device with a larger screen size will require more power than one with a smaller screen size.

This is why you must also take into account how you will be powering the device.

It’s also essential to consider the resolution. The higher the resolution, the more information is collected. This is important when differentiating fish from other underwater elements. However, the higher the resolution, the higher the price.


A fish finder with SD card slots is an excellent choice for anyone who needs to save waypoints and record sonar features.


Wi-Fi or Bluetooth connectivity allows you to sync your device with the fish finder GPS. You can access different features through an app on your smartphone.

Additionally, this will make viewing your phone notifications on the screen easier.

Waterproof Design

All electronic devices are sensitive to water. Some are more sensitive than others. Waterproofing your device is part of the protection it offers when in the water.

With IPX7, you can submerge your device for up to 30 minutes. With IPX8, it will be more resistant to water up to 1 meter deep for 30 minutes.

Power Output

A GPS fishfinder with high wattage will perform better than a unit that uses lower. The higher the voltage, the faster the unit will display the sonar readings.

If you plan to fish in deeper waters or in areas where the water is very turbid and muddy, then the one with more wattage will allow you to see more fish.

You’ll also have a clearer view of your surroundings on the screen of your fish finder.


The chart view is the most optimal way to view the map information, helping you plot your course and visualize your current position.

A fishing chart contains detailed data, including the depth capability, vertical resolution, and quality of the bathymetric profile. This chart is best for offshore deep-sea fishing hotspots.

A navigation chart has a plotter that shows you the part of the ocean you are in and various charts and information about it.

The information includes a display of detailed buoy markers, spot soundings, safe water passages, marine services, exposed wrecks, and light beacons, among others.


A fish finder GPS is one of the essential tools you can use to help you catch fish. If you’re not careful, it could also become an expensive mistake.

These devices are expensive, but many anglers consider them a must-have when going on the water.

When looking for the best fish finder GPS combo, the right idea is to find all the features you need. Hopefully, this fish-finding guide will help you narrow your options and choose the right one.
