Another great point about this baby is that it allows you to either use the SplitShot transducer that gives you a full scan of the place right below your boat or to use the CHIRP sonar technology that provides the fish arch right on the screen.

However, because this is a simple device, it does not come with a charger or a carrying case.

6. Garmin Striker Plus 5cv – Best Model For Beginners 

Garmin Striker Plus 5cv

Like the other models, this babe comes with a durable transducer; however, this transducer can be mounted in various ways. You can install it on your trolling motor and inside the hull. 

It is one of the most fabulous sonar GPS combos as it features CHIRP traditional sonar plus CHIRP ClearVü scanning sonar.

Moreover, you can use Bluetooth to share information like the weather conditions, your location, and so on. 

Sadly, I have to tell you that its sunlight-readable screen display that has a resolution of 800 x 480 pixels is very small at only 5″, so you will have to zoom in a lot to clearly see the fish displayed on the screen.

Pros:

  • Great for beginners

The built-in Dual Spectrum CHIRP sonar provides two ways of searching for fish: wide mode and narrow mode. The wide mode offers maximum coverage, while the narrow mode provides maximum detail. Moreover, the sonar identifies well-defined fish arches and provides the users with clear views of the fish-holding structure and the bottom.

How To Pick a Fishfinder GPS Combo

1. Display 

The thing you should seek is readability. You would not like it if you look at your display screen and understand nothing, will you? 

Look for a screen that allows you to quickly and easily understand the information it presents and know what to do with this information. 

There are also various screen sizes and types that vary from 4-inch monochrome display to 10-inch full-color display. For accurate, crisp details, go for 5-inch and 7-inch color screens. Also, you must put the resolution into your consideration. It varies from 320×240 to 640×480, depending on its manufacturer’s specifications.

As a rule of thumb, the more resolution, the better. However, this does not mean that less resolution is terribly bad because it would be okay if it’s a grayscale display. To sum up, if you have enough money, it is better to go for a higher resolution.  

You should also see the way the boxes are arranged, whether the graphs are easy or complicated to read, and the size of the texts and numbers on the screen. 

2. Transducer

This is the heart of your device. If you do not know what the transducer is, you might as well not get a fishfinder at all. A transducer is this part of the device that sends the sonar waves into the water. Since the sonar beam works at a particular frequency, the transducer has two types: a narrow range and a wider range.

Each type of these is used for a particular target. If you need it to work for large depths of water, go for the narrow range. However, it can only cover a limited area. In case you need to cover a wide area, go for the wide transducer, but you must know that it can’t see much more in-depth.

If you need both, you can! Just go for a fish finder that comes with dual-frequency. It covers broad areas and deep depth of water. 

3. Scanning Modes 

There are two types of scanning, namely, side-imaging scanning and down-imaging scanning.

Side-Imaging Scanning

The transducer scans the water that is directly under the boat using a single beam of sonar wave. This method results in a clear output; however, some objects cannot be easily identified. 

Down-Imaging Scanning

Unlike the Side-Imaging Scanning, this type of scanning uses two beams of sonar waves. It results in many clear images on the screen.

4. Operating Frequency

The transducer sends sonar sound waves that are measured in frequency. As we already know, higher frequency means a clear image. The frequency generally ranges between 50khz to 220khz, and it is directly proportional to the transducer’s two modes. Like I said before, it is better to get a dual-frequency fish finder. 

5. Power 

Like any device, power is a crucial aspect. The power of the device determines the level of depth of scanning, and it ranges from 400 watts to 1200 watts. The more the watts, the more you can see in the depth of the water. Moreover, higher power fish detectors are suitable for working at high speeds. 

However, the more power, the more the battery gets consumed, and therefore runs for a shorter time. So, the best thing to do is to choose the power that is most suitable for your needs. 

6. GPS Technology

The fact that there are fishfinders with built-in GPS blows my mind! It enables you to specify waypoints and mark them at your favorite points, so that the next time you go fishing, you know the sweet spot. Moreover, some devices have map pre-loaded for navigation that can be used as a navigation system to lead you to the perfect fishing spot.

Getting a fishfinder GPS combo will not be as expensive as you think; on the contrary, it will save you the amount of money that you would spend on buying two separate products. 

7. Portability 

There are portable and fixed fish finders. The portable one is great for those who want to remove the detector from their kayaks after fishing. They are easy to carry, and they take up less space than the fixed ones. 

However, if you own a kayak and you do not want to spend time fixing the portable detector on your kayak every time you go fishing, then go for the fixed models. 

What Are The Benefits of Using a Fishfinder GPS Combo, and Why Would You Use It 

Have Great Computing Performance in a Small Package 

Usually, commercial fishermen have a lot of space on their boats so they can accommodate a lot of equipment. However, amateurs and semi-professional fishermen do not usually enjoy this much space. This is no longer a problem for beginners because they can finally have one equipment that provides them with various functionalities. 

Save Data and Information, So You Don’t Start From Square One Next Time 

If you have gone fishing before, you definitely know what it feels like when you are leaving a perfect fishing spot. You keep wondering if you will be lucky to find it again. With a Fishfinder GPS Combo, you do not need luck. It will enable you to navigate quickly and successfully to your favorite fishing spot.

The reduction in the physical size is accompanied by increasing the computer memory so that you can save all the info of your top fishing spots in order to return to them no matter where you go. 

Moreover, they do not only save the locations, but they also save depth, water conditions, and schooling/fish behavior, so that you can return to the site even if you haven’t gone to it for months or even a year. 

All-in-one Equipment 

When you have all the equipment you need in just one device, this will lessen the stress because you will no longer need to check the battery of each device. Make sure they are all with you before you go fishing. 

Get a Better Idea of What Is Underwater 

With better screens and better imaging, you can see what you’re fishing for and where the fish are. 

Frequently Asked Questions:

What’s The Difference Between Chartplotter and GPS?

The main difference between them lies in the show of a map. The GPS provides your location without showing it on a map, but the Chartplotter takes your location and places it on a map. 

To sum up, all chart plotters use GPS and not vice versa. 

What is a GPS Plotter on a Fish Finder?

It is a device that helps fishermen know their exact location in the water, as well as the location of harbors and ports. It also finds and locates fish, so that the fishermen do not waste their time in an area with no fish at all.  

Are Fish Finders Waterproof? 

Yes, they are. However, some models are only water-resistant. Such models cannot be submerged, or else they will be destroyed. 

Final Thoughts 

I believe you have already found what you are looking for. If not, I will help you by recommending some of the best models so that you can easily find the best fish finder GPS Combo. 

If you need it for a beginner, you can go for Garmin Striker Plus 5cv or Humminbird Helix 7 SI. Each of them has its impressive features.

If you need to share your fishing spots and fishing experience with your friends, get Garmin Striker 4 or Garmin Striker Plus 5cv.

I understand that the variety from which you are allowed to choose can be a bit confusing, but if you re-read the article again, the image will be clearer.
