Each fish, as well as every fishing ground, have their unique necessities and requirements. As a result, there is no one product that is the best fish finder for all situations. This is a buying guide of the best fishfinder GPS combo, helping you find that which will perfectly suit your needs.

What is a Fish Finder?
Points To Keep In Mind While Choosing the Best Fish Finder
The main factors that are used in the choice of the best fish finders are dependent upon the design, development, and ultimately the production of the products. Below are some of the categories used by savvy fishermen to make comparisons between different products before making an apt decision:
- Transducers: This is the fish finder’s part designed to send out and in return receive the sonar signals underwater. Different fishing types require different appropriately corresponding transducers. The deep signal sending transducers are needed for ocean fishing whereas anglers on ponds and other small water bodies would prefer a wider angle of sound wave transmission from their transducers.
- Frequency: Higher fish finder frequency results in the reception of more details on your fish finder’s screen. Deep-sea trawlers will need the low-frequency transducers while the high-frequency versions work best for the shallow angling. The most common frequencies range between 50 and 200 kHz.
- Cone Angle: This is an angle representing the width of the “net” caught by the signal when deployed from the boat’s bottom into the water. Typical cone angles range between 15 and 20 degrees with other extreme cases going to about 9 and 60 degrees. Advanced anglers prefer products coming with different cone angles hence versatility
- Display Screen: It will be prudent for you to consider the modern full-color screens, rather than the traditional black/white screens. It’s fortunate that these clearer color screens are fast becoming more and more popular hence almost certain that your choice of the product would anyway feature a color screen.
- GPS Capabilities: GPS is a must-have feature of any reliable fish finder; no wonder our buying guide specifically narrows down to the GPS combos and no other. You will need a GPS product when you go fishing. Why buy a separate GPS apparatus when you can have one product that has all you need?
- Power: The power of a fish finder is the determinant of the sonar’s operation speed, with fast units featuring higher wattage ratings.
- Scanning Capabilities: There are two main ways used by fish finders to do the scanning. These include down scanning and side-scanning. The former is a very powerful, focused, and effective method that only focuses on the fish that is directly underneath the boat. The side scan on the other side covers a wider area but isn’t as precise as the down scan method.
- Others: Other features to consider include design & durability, portability, manufacturer, and price among others. Price comes last on the list as it is never a prudent idea to buy your fish finder based on the price factor alone.
Why Do You Need a Fish Finder?
This buying guide of the best fishfinder GPS combo helps you to choose the best product. With the most appropriate product, you will end up with the most out of your fishing expeditions. What is the need of aimlessly floating on water and going home after several hours without anything to show for the time spent on the waters? A fish finder will optimize your efforts of putting food on the table.
Types of Fish Finders
There are three main types. These are:
- The standalone Fish Finder: They are the most affordable and economical and the best choice to be considered by those looking for a product that goes for less than $200. The models display elements found beneath the boat, with most of them featuring larger screens. The GPS feature isn’t found in these products. They are the best options for small boats floating on inland lakes.
- Combination/Chartplotter Fish Finder: This product comes with the GPS functions and a split-screen for viewing surroundings. It works best for those owning mid-sized boats, they do fishing on larger water bodies and they also have a little more cash to spend. The combination fish finders are also referred to as combo fish finders
- Networked System: These are the most advanced products for the experienced or rather big boys and big girls. There is nothing found in a fish finder that isn’t found in these ones. Be it vector GPS charts access, access to SiriusXM satellite radio, raster or radar, you will have all these at your disposal. Wi-Fi/Bluetooth options can also be made available. They are thus the best product found on the market

FAQ’s
How Does a Fish Finder Work?
Electrical pulses are sent to the underwater transducers by the fish finders. The pulses are transmitted as sound waves, with resultant reverberations back to the transducer whenever the sound waves hit something. The reverberations are then captured and relayed back to the finder, which in turn translates the information into compositions, shapes as well as sizes.
Is it possible to Sync a fish finder with a mobile device?
Yes. Provided your finder comes with such capabilities and your mobile phone can also allow for app installation
What’s the step to take when a transducer breaks?
In most cases, you may be compelled to buy and install a new model but consulting your owner’s manual or manufacturer before taking any step would be prudent
What Do I Do if my Fish Finder Stopped Working?
You need to determine the source of the problem. Try charging the device, and plug it into an Internet-connected computer to see if the computer recognizes the device. If the screen freezes or is slow to respond, try powering the device down and restarting it. You might also want to try downloading updated firmware for your model. If you suspect water damage, consult your owner’s manual for warranty information and instructions on contacting their customer service department.
What step do I take if my fish finder isn’t working?
Start by separately running your transducer cables from other independent wirings so as to minimize interference. If it doesn’t work, consult the manufacturer.
