Have you ever experience fishing with the fish finders?

If yes, you definitely know how helpful are those devices. The best fish finder not only helps you to catch more fishes but also saves your lots of time.

The fish finder uses the sonar to send the radio waves (electromagnetic energy) into the water, and that waves reflect back to the sonar.

Based on these waves, the fish finder shows the internal structure of the water in the graphical and chart form. So, you get the idea about, where you can catch the more fishes.

Moreover, some devices provide some extra features like water temperature, 3D view, 360 Imaging, side imaging, dual beam, route plotting, wireless control and many more.

The Humminbird HELIX 9 fish finder is the best fish finder in our list, which features 9-inch color TFT display and the 800 x 480-pixel resolution.

This fish finder is having dual frequency supported sonar system and inbuilt GPS feature, which will show the real-time accurate data on the screen with chart plotting. The dual beam means you can use both frequencies at the same time, which will show you more detailed data.

This 1000-watt powerful unit can show the deeper data up to 1,500 ft. on the standard frequency, and 3,000 ft. on the 50Khz frequency. Which is quite impressive. But keep in mind that this deeper range can slightly decrease in the salt water.

Additionally, you can use these both at the same time.

On the latest upgrade, the Humminbird HELIX 9 can supports side imaging, which is also a plus point to consider. Additionally, this unit is also capable to support some advanced technologies like 360 imaging, but you have to purchase a compatible sonar system separately.

The Simrad GO7 XSE is the only fish finder that comes with 7″ multitouch display, but this is not the only feature which makes this unit special.

Then, what are the special things about this fish finder and GPS combo, which we like? Let’s find out.

First of all, as we said earlier this display of this fish finder is multitouch supported and very bright, which allows you to view in bright light as well as makes this unit very easy to use.

Next, this GPS depth finder combo comes with CHIRP sonar technology, which on the 50/83/200/455/800 kHz frequencies. And it supports dual beam mode too, which allows you to scan on both levels at the same time i.e. deeper and shallow.

Well, the deeper range of this unit is not too impressive, you can scan up to 1,000 ft. with CHIRP sonar, and 300 ft. with the standard. Moreover, the frequencies that are supported by the dual mode are 83 Hz and 200 Hz. The low frequency (83Hz) works best for deeper water, and the high frequency allows you to do the deeper level scan.

However, if you want the ForwardScan you have to purchase the different transducer.

When we think about the recording of the sonar, this unit allows you to record into its internal memory or you can use your own microSD card as well. Additionally, the sonar of this fish locator comes with a temperature sensor, that you can track the water temperature in real time.

As we said earlier this unit is having inbuilt GPS of 10Hz, which not only accurate but also very fast when we think about the update time. Because your data will be updated 10 times within a second and you can track the speed of your boat too.

Like Humminbird devices, this fish finder also comes with the insight charts of the USA, which provides 8,000 US lakes and rivers along with contour line and depth data. That is very useful and time saver for any fisherman.

The waypoints storage capacity of this depth finder is 10,000, so you can save your favorite location instantly with them. And, you can use that data for finding your favorite spot when you came back for fishing again.

Don’t worry, you don’t need to save the waypoint manually, this unit is set to automatically draw the movement and you have to need to just save them for reuse.

In the starting, we have discussed the display, that is of 7″ multi-touch. But here is the main point, this display is having LED backlights and the 800 x 480 resolution. Additionally, this unit is having IPX8 water resistance.

Apart from that, this fish finder also has built-in Wi-Fi, which allows you to map download or software updates. And, with Bluetooth audio integration you can stream music through this unit or listen the inbuilt FM/AM radio.

The Simrad GO7 XSE Chartplotter/Fish finder is another considerable option after Humminbird HELIX 9, which offer CHIRP sonar, inbuilt GPS, multitouch 7″ display and Wi-Fi and Bluetooth connectivity.

This unit is very easy to use with its clear interface and touch-enabled display, I think if you want a fish finder which having all ordinary features along with touch display, then this unit is recommended.

You have probably read our all different types of fish finder’s review above, but this unit is totally different from others.

First of all, the   fish finder is the cheapest Wi-Fi portable unit, which works with both Android and iOS devices. Moreover, this unit is rechargeable and which can last up to 10+ hours. I think this is sufficient backup when we consider the price of this portable fish finder.

Practically, the ReelSonar IBobber unit will not work like other expensive fish finders, that provides CHIRP sonar, deeper scanning and other stuff like that. But this fish finder really does his job and allows to scanning up to around 135 ft. deeper.

As you can see in the image, this unit doesn’t come with the GUI (Graphics User Interface), but the free app provided by the iBobber can turn your smartphone or tablet into a monitoring unit.

This apps works on the Bluetooth connection, that provides a reliable connection up to 100 ft. away. The app monitors the water temperature and weather condition also, that is very useful for fisherman. Apart from that, there is an inbuilt GPS feature is also included, that will make your fishing experience easier.

If you are a fishing enthusiastic and don’t want to spent more on the fish finder, then ReelSonar iBobber is a perfect choice. However, it is not the “best fish finder” but it really works well.

If you have the slightly higher budget, then you can check out our other recommendation i.e. Deeper PRO PLUS Smart Sonar, that is also a smartphone fish finder.

Pros
  • Rechargeable battery 10+ hours of backup time
  • Free app on iOS and Android
  • Light, portable and very easy to use
  • most affordable
Cons
  • Limited deep scan range (only 135 ft.)
  • The Bluetooth range could be better

Portable Fish Finder – Buyer’s Guide

Before choosing the best fish finder there are many factors that should be considered. Below we are providing some steps which will help you to find your best fish finder for the money.

What should consider before purchasing the best Fish Finder?

best fish finder power in watt

This shows the how powerful is your fish finder? The more wattage allows you to see the deeper into the water and find the more fish. Moreover, the low wattage power is useful for shallow water fishing, and better to see the surrounding area.

Frequency is one of the most important factors to be considered before purchasing any fish finder.

You have to understand the frequency range that best fit for your fishing style. There are mainly three types of frequency comes in fish finders, and they are single, dual and multiple.

And, amongst of three, they come in 50, 83, 192, or 200 kHz.

But what does means of these frequencies in the fish finder?

These frequencies define the characteristic of any fish finder. I mean, how much deeper you can analyze and how detailed data you will get?

You can understand like this, high-frequency (192 or 200 kHz) fish finders are ideal for shallow water fishing, and on the other hand low frequency (50 or 83) is useful for deep water.

But keep in mind that, the high frequency provides you much clearer data on your screen.
