Types Of Portable Fish Finders

This the conventional style of fish finders consisting of a Nylon carry case to hold all the components of the kit together. This unit is best suited to small boat ice and shore fishing techniques.

Mountable Fish Finder

This portable finder unit allows being temporarily mounted on the side or transom of the boat and requires the use of a float tube as an essential.

Castable Fish Finder

How to Use a Portable Fish Finder:

The use of any portable fish finder varies from model to model. It is a known fact that technology can turn out to be quite complex if not explained in detail. Therefore, we briefly summarize how to use a portable fish finder below to help aid you in its working no matter what model you use and you can also read how to use a fish finders.

The first step is to turn on the scanner of the unit and connect it with your phone. Next, adjust the settings according to your preferences and desired fishery target and allow the device to identify selected hotspots.

Now, cast the fishing line or castable unit in the sea and wait as the results start to display on your screen. The fish indicating symbols and colors may vary based on the model you use and as stated in the manual provided.

How Does a Portable Fish Finder Work?

A portable fish finder works by using sonar waves to detect fish in the water. The sonar waves are sent out from the transducer, which is a small disk that is mounted on the back of the boat.

The transducer sends out these sound waves and then receives them back when they hit something solid, like a fish. The sound waves will bounce off of the fish and return to the transducer. The transducer then translates these sound waves into images on the screen of the portable fish finder.

These images will show you how deep the water is, what kind of bottom structure there is, and where the fish are swimming. All of this information is important when you are trying to catch fish!

Buying Guide Of Best Portable Fish Finders:

A portable fish finder is always an expensive investment and for a beginner, it can turn out to be confusing too. Before purchasing this device, numerous things have to be taken into consideration. These factors help determine the efficiency of any fish finder and are listed down below:

1. Power Output:

The first thing that you should look at is the power output. The power output is measured in watts and it will determine how far away from your boat the sonar waves can reach. If you are only going to be fishing in shallow waters with fish finder, then you will not need as much power as someone who wants to use their portable fish finder in deeper waters.

2. Black and White Screen or Colored Screen.

Although modern fish finders mostly offer colored screen displays, black and white ones are still offered. If you are on a tight budget, a black and white screen is the best for the time being otherwise a colored display is perfect for easy data viewing and understanding.

3. Screen Resolution.

The defined number of pixels contributes to image detailing and clarity. A portable fish finder should offer at least 240 × 160 screen resolution to display a moderately clear view. The higher this resolution is, the better the image quality but also the higher the price of the device.

4. Water Resistance.

The JIS and IPX rating of the transducer determines their resistivity towards the water. A rating of 5 and 6 bares low water resistivity whereas 7 is perfect for unit’s submersion for about thirty minutes. 8 is the highest rating and withstands resistivity to water for an incredibly long period.

5. Transducer Mount.

The transducer is the component responsible for scanning the view underneath. It comes in two different mounts to choose from being heavy-duty and ransom amount. While ransom mount is easier to install, the heavy-duty mount is complex but perfect for bigger boats.

6. Frequency

Another thing that you should look at is the frequency of the transducer. The frequency will determine how clear the images are on the screen of your portable fish finder. Higher frequencies will give you clearer images but they will not penetrate the water as well as lower frequencies will. This means that if you want to use your portable fish finder in deep waters, you should look for one with a lower frequency.
