The 5 Best Fishing Fish Finder For The Money Reviews of 2018

Fish finders are the latest technology available that ensures you always find fish.  In this review, we will talk about our five favorite fish finders including the best portable fishfinder for ice fishing. Before that, however, let’s first understand why you would want to use a fish finder and how it can help you no matter what kind of fishing you do.

What is a fish finder?

Simply put, a fish finder is a device that is used to locate fish in the water. SONAR ( Sound Navigation and Ranging) is used to do this. Whenever anything makes a noise or moves (including fish) it sends a wave around it which bounces off objects and return back to the object that released the echo. This is how whales are able to locate fish up to 50 feet (15 meters) away.

On a fish finder, the location of the fish is displayed on a digital screen usually using a ‘fish’ symbol. As the boat approaches the fish, the screen will display arches on the screen to indicate that you are nearing the location of the fish. The best ice fishing fish finder will allow you to adjust the sensitivity which is called peaking the transducer.

In order to function, a transmitter is placed on the boat which is responsible for sending signals through the water. This transmitter sends echoes which reflect back and give you an idea of what is under the boat. The screen displays different colors and symbols for different things-for fish, corals, stones, and others. This way, you won’t’ get confused whether what you are seeing is a school of fish or not.

Is it the same as a flasher?

One thing that both a fish finder and a flasher have in common is that they both use SONAR technology to locate fish. Since flashers are very portable, they are a favorite tool for ice fishing.  You can think of it as an ice fishing GPS. There are three main differences between a fish finder and a flasher:

1.  The way images are displayed

One thing that differentiates a fish finder and a flasher is the way images are displayed on the screen. A flasher makes use of colors that change from green to yellow to red. The sediment may appear as green then turn to a thick red line while a bait fish would appear as a thin green line.

2. The way they are used

While you will need to attach a transmitter to your boat if you are using a fish finder, you will need to drop the transducer down your ice hole for ice fishing. Then, you set the range according to the deepest range setting to the actual depth.

After this, adjust the gain or the amount of power the transducer emits. Once the screen is clear, zoom into the section of water that has high chances of having fish. Finally, you will be able to drop your lure which you will see as a bar on your screen.

Tips for choosing ice sonar fish finder

Whether to purchase a fish-finder or a flasher is a matter of perspective. Here are some tips to help you make the right choice:

  • The type of fish finder you want. Do you want a device specifically for ice fishing or an all-season package? Ice fishing flashers are not designed to be used in the summer so remember this when you make your decision.
  • The depth of your fishing. Fishfinders often come in three frequencies namely 50 kHz, 83 kHz and 200 kHz which are designed for different water depths. Fishfinders that only function for a specific depth is cheaper than those who can work on different frequencies.
  • How portable do you need it to be? You will need a 12 V marine battery on your boat if you are to work so if you don’t already have that, you will need to make additional purchases.
  • Understand the different features and select which fits your needs. Some of the most common features include: (5)
    • CHIRP- Compressed High-Intensity Radar Pulse which uses a spectrum of frequencies instead of just one. This covers a larger area.
    • Broadband Sounder-uses a single frequency. It can either be 200kHz (for shallow depths), 83 kHz ( mid-range depths) and 50kHz (for very deep water).
    • StructureScan HD-these finders emit a high frequency which translates into charts or pictures.
    • SpotlightScan- enables horizontal scanning of the surrounding area which boosts fish-location capabilities.

Once you fully understand the different types of fish finders brand, you can compare this to what you are looking for. For example, if you are targeting fish in deep water, you would need either a 50 kHz finder or one that has CHIRP capacity. However, if you want to be more versatile, always make sure that your fish finder uses CHIRP technology.
