Fish finder is one of the most modern and innovative devices which could your fishing sessions much more enjoyable. There are many types of fish finders with different features, options and prices. In order to buy the best fish finder, you must have spent a lot of time and money.
However, even if you have found the best fish finder in the market, there are certain things that you know about this device in order to maximize its use. The most important thing is you know how to use this innovative device.
For some people who have just bought this finder, it takes some time to understand the meaning behind all the dots and lines. Unlike what you might think at first that the fish finder will show you where the fish are and show the images of fish on the screen.
How It Work:
In fact, fish finders work as sounder- they send waves through transducers and bounce back when the waves meet obstacles which will show as echoes on the screen. So basically, what they show on screen would be dots and wavy lines.
Although they may sound confusing and complicated at first, if you know how to learn them, you will get the most out of it quickly.
Here Are Some Tips On Reading The Fish Finder Screen:
First, all the waves’ echoes will appear from right to left on the screen therefore, the latest result will be shown on the right hand side of the screen.
When you are moving, remember to look at the right hand side of the screen to look for what you just passed by.
When you stay still, although the screen seems to be moving, what you see on the screen is the same reading over and over again. If you cast a line and follow the line from the top, you will see the line follow to the bottom of another line on the screen.
For different types of fish finder, there will be different techniques to read the results on the screen. 3 types of fish finders include fish finder with traditional transducers, fish finder with high frequency and down image ( or down scan) and fish finder combing with chart plotter.
Fish finder with traditional transducer
This kind of fish finder is very basic and is one of the oldest models of fish finders. It has very little additional features. That is why this one is the easiest to read.
On the top left or right of the screen, you will see a number showing the current depth of the water. There will be a number showing the water temperature if your fish finder has a temperature sensor add in, or the speed you are currently run in some models.
In most of the fish finder, on the screen you will see a thick or thin red way showing the bottom. If there are some green dots above the red wave, it means that some sonar waves could be able to penetrate through the bottom- showing how soft the bottom is.
If the bottom is hard, you can just see the red wave but nothing above that.
Below the red line, you could see some little things attaching to the bottom. It could mean any kind of structure where fish are likely to hang around. This is where you can stop to find fish.
Fish finder with high frequency and down imaging
The way the result of the sonar waves showing in the screen is like the traditional fish finder, from right to left. But unlike the traditional fish finder which shows the bottom on top, in this case, the boat will appear on top and everything below it is what you just came crossed.
On the screen, the numbers showing the depth of the water, the temperatures as well as the speed are also available.
The higher the frequency is, the clearer the image will be shown on the screen.
In a typical screen of a down imaging fish finder, there will be a line to divide the screen into 2 sides, with the areas near the line is the water and the areas on the left and right sides are bottoms.
With this device, you can see the shadows of trees as well as small dots. Based on the sizes of the dots you can guess the real sizes of the fish and hence, guess the types of fish.
Be careful as small dots you see could be fish or some debris.
Fish finder combining with chart plotter
On the screen of this type, you can both view the sonar reading like what you see on these other two types as well as the navigation charts.
With this feature, you can see where the boat is heading to as well as the obstacles and the underwater where it passes by.
Here are some general details on how you should read the screen in a fish finder device. Understanding how the lines and dots work in each type of fish finder will help you to have a better view of the underneath as well as searching for fish more easily.
I hope that this article is interesting and informative so that you will be able to understand how to use your fish finder and have a very interesting and pleasant fish hunting session.
