    Factors To Consider When Looking For The Best Fish Finder GPS Combo

    There are only a few things to consider to find the best fish finder GPS combo. Other features will just be determined by your personal preferences and budget.

    • envira
      Screen Display
      The quality of a unit’s screen display is important because you need clear readings for fish finding and navigating. Consider the size and resolution of the screen that will make it comfortable for you to see.
      Go for the fish finder with the most massive screen and highest resolution that will fit within your budget. This will help you locate fishing spots and read information. 
    • envira
      Frequency
      The frequency range of a sonar device determines the amount of information it can give. A wide range of frequency provides you with an accurate image of the objects, fish, and landscape underwater. More information and details can be transmitted with a higher frequency.
      However, higher frequencies do not work as well in deeper waters while lower frequencies give you fewer details. Therefore, choose something that has multiple frequency options that allow you to shift and adjust depending on your needs. 
    • envira
      Power
      Deeper and better readings are provided by higher power inputs. Fish finders can generally display 400 feet readings for every 100 watts. The combination of the power and frequency also determines a device’s image clarity, detail transmission, and width and depth of coverage. 

    Conclusion

    Choosing a Fish Finder GPS combo depends on your particular needs as a fisherman. However, I have chosen the Dragonfly 4 Pro Navionics+ by Raymarine because it delivers the essential features for me at a reasonable price point.

    It has a nice display, reading power, a practical frequency range, and many other useful features. If that’s also what you need and the price seems logical for you, then give it a shot. Otherwise, the other four options are also great.
