Every Angler Should Try These 5 Best Fish Finder GPS Combo 2018

Every angler knows that it’s difficult to catch fish if you don’t know where they are. You have to spend some time locating them and finding the perfect spot to catch them.

I’ve been an angler for quite a while now, and just like you, I’ve spent a lot of time trying to find where the fishes are.

I’d go out fishing two times a week - especially during the weekend - but never got a single catch because I was fishing blindly in the water.

There was a time when I no longer enjoyed it and thought of quitting.

But then something came up. My friend Garret invited me to a local boat show. Garret took me inside his boat and showed me the fish finder GPS Combo.

He had a Garmin model, and he showed me how the unit could show all these topographical maps, thermal images and be used to locate fish.

I was blown away by the experience. The solution to my problem was right in front of me.

I knew I had to get one, but Garret said there are different models in the market and I should choose one that will work best for me.

And so I did my research and came up with the list of top 5 best fish finder GPS Combo that every angler should try.

So keep reading until the end...

II. Important Features to Consider in Choosing the Right GPS Combo

1. Screen Display. GPS comes with display screens. The interface or display is decisive in allowing you to see through bodies of water and process the information displayed on the monitor. It is important that you understand what is displayed on the screen so you can quickly and safely navigate through waters and find fish with ease. Thus, readability must be one of the features of the display that you wish to purchase.

You can find different designs available in the market that will suit your preference. Displays come in various colors and sharp details. But they also come in black and white displays that allow you to differentiate objects through contrasts in color.

Here are initial features that can help you select the right display for your GPS and fish finder:

  • check
    Readability of the Graphs
  • check
    User-friendly interface
  • check
    Display size

2. Device Size. The overall device size is critical in your choice. A larger device can probably give you larger displays but it will also be bulky and space-consuming affecting its portability.

The appropriate size that we endorse is the mid-sized device. It is the right size that will allow you to store or keep it without losing it easily (too small) or to transport it without having problems (too large). The device also comes with the right cases for storage and transport.

Screen size can also vary from the 3 1/3 inch Lowrance echo to the 5 inch Lowerance displays, to a 7 inch Garmin, or even larger. Mind size would be somewhere between 5-6 inches. Such size would give you enough screen space.

3. Technology Highlights. If you want to get the best, you will definitely get the fish finder with the latest upgrades including the latest GPS. The latest models are often the most efficient in fish finding.

Here are some highlight features to look for when choosing the best fish finder and GPS before you go on your next fishing expedition. These features have very important use if you want to find fish with accuracy and speed. These include the following.

  • check
    Temperature Readings – Temperature readings done by built-in sonar.
  • check
    Depth Reading – The ability to go down deeply in salt and fresh water and give accurate readings of the water’s depth.
  • check
    GPS Reading Speed – The GPS’ ability to pin point your location fast in proportion to your boat’s speed.
  • check
    Frequency of Sonar – Different models will give you different frequencies like 50 kilohertz and 200 kilohertz. Higher frequency usually work better is shallower water; lower frequencies work better in deeper water. By choosing a dual frequency model, you get the best of both worlds.
  • check
    Accuracy of Target – The ability to get target separation and accurate results at different depths.

4. Resolution of the Screen. The resolution of the screen is one crucial feature in choosing a fish finder. The resolution is the measure of how obvious the display on the screens is. A high resolution equates to clear images displayed on the screen allowing you better and more accurate readings.

5. Frequency. The frequency of the fish finder is equivalent to the number of ultrasound or sonar pulses the transducer emits. These frequencies range from 15 kHz to 200 kHz. You can adjust your frequencies to locate fish depending on the depth of the water. A lower frequency is usually used in looking for fish in a wider area.

A higher frequency is usually used in a narrower area. Higher frequency shows clearer images on the display monitor. The usual frequencies used are 50 kHz and 200 kHz. In dual transducers, the device uses two cones or two sonar beams.

The use of the appropriate frequency in the proper time is crucial in efficiently tracking down fish and catching them.

If you want to catch fish in shallow waters, you can adjust your frequency to high which emits sonar beams at a smaller area and narrower cones. If you're going to catch fishes from deep water, you can adjust the frequency to low allowing you to search for a wider area and deeper depth.

6. Transducer. A transducer is a critical part of the fish finder. It is the part that emits the signals of sonar waves into the water and receives signals that bounce back to the fish finder monitor which interprets the signals into actual graphs, shapes, and images. It is important that your transducer is functional and reliable.

An example of a transducer is a transom mount. This transducer is convenient to install or easy to mount.

7. Power. Fish finder, as with other devices, consumes power. It is imperative that you check the power consumption of your device. The power consumption is computed in watts. A high wattage gives more power and thus, good device function and display. A low wattage gives you low power and thus, poor device function and display.

Your consumption will also depend on the extent of use of your device. If you use the device to fish in shallow waters and where fish can easily be tracked, you can do with low wattage. If you use the device for deep-water fishing and where fish is often difficult to see, you can opt for high wattage.
