Are you a beginner or a seasonal fisherman who have probably heard of fish finders or maybe you have used these fancy fishing accessories in the past but not really sure about how does a fish finder work? Well, then let’s go into details about how you can apply these devices in modern fishing processes to locate the fishes in the water.
A fish finder works on SONAR (Sound Navigation and Ranging) technology and it includes systems like GPS, electronic compass, radar, etc which makes the device more useful. This is one of the best ways to increase the number of fishes you catch and it makes your fishing experience more enjoyable with the information and knowledge of how does a fish finder work.
#1, Understanding the Nature of a Fish Finder
Let’s try to analyze the basics first before we go in depth and you’ll be happy to know that it isn’t a lot that you will need to know in order to master how does a fish finder work. A fish finder typically consists of mainly two parts: a display and a transducer.
- The display has the basic computing power and it takes the raw data from the transducer and then processes it in easily readable manner. It is generally placed in the boat or if it is a portable one, it may be placed on angler kayak.
- The transducer is the main component which sends the sonar waves down the water and returns information when it hits something. It also estimates the size and depth of the object to make sure it’s a fish and not any rocks or logs in the water.
#2, Insight Into the Working Principle of How Does a Fish Finder Work
Now we move to the detailed description of how does a fish finder work to help you with your next fishing experience.
The display, as the name suggests, is a simple display screen which has the basic power of converting raw data into user readable format. It collects the data from the transducer and then processes it for easy understanding and interpretation of how does a fish finder work.
The transducer is used to send sonar waves or sound waves into the water for the purpose of screening. When the waves hit something in the water, the transducer tries to guess the nature of the object by estimating its size and depth. It then sends the information back to the display.
#5, Depth Finder
Every fish finder which is available on the market has a depth finder feature which helps you to determine the depth of the water while fishing. The depth finder is mostly associated with the transducer component and both together helps to find the depth of the water easily. The depth of the water is useful because you can determine what types of fishes can be found in that environment and thus what all possible varieties of fishes are there right beneath your boat.
The depth finder is located in the top right corner of the display screen on most of the fish finders. The total depth of the water will be measured in meters rather than in feet and the measurements are pretty clear and accurate which makes it easy to read and understand how does a fish finder work.
#6, Water Temperature
While fishing, one important parameter that you must find out is the temperature of the water. The temperature of the water which is displayed on your fish finder is very useful because it is used to determine where a specific species of fish might be living in water. Some types of fishes prefer to live in warm water, while other types of fishes prefer cold water to live in. Thus you’ll have no problem to find the right water spot to search for the particular fishes you are looking for. You can also find out which types of fishes are living in any particular water temperature in case you don’t know.
#7, Speed Sensor
The speed sensor determines how fast you are moving in the water on the boat. You can consider it as a speedometer of the fish finder of your boat. Many would not consider this factor, but the speed of the boat certainly plays an important role to determine how does a fish finder work. So make sure to use this feature of the fish finder to the fullest.
#8, Colour and Echo Return Strength
Few of the fish finders supports only gray scale or black and white image screens while others can support coloured images. Colour is an important parameter to determine how strong the echoes are returned to the unit. The density and hardness of the object also help to estimate how quickly the echo will return back. When the strength of the returning echo is strong, it produces a darker coloured image and if the strength is not as strong the image thus produced will be of lighter colour.
The bottom of the water where you are fishing is represented by a dark or light line. When the line is dark, it signifies that the bottom is harder and less porous and when the line is a lighter line, the bottom is likely to be made of soft material like clay.
#9, Pro Tip
With a little experience of using the fish finder, you will be easily able to recognize a school of fish under the water and identify the types of fishes, and if they are likely to be caught or not with the help of this gadget. Once you are used to sighting fishes on the display, you can easily identify how easy or difficult it is to catch them.
Learning about how does a fish finder work is relatively easy as you can see. There are plenty of fish finders available on the market ranging from $50 to several thousand. The basic models weigh a bit more, give rough estimates than the intermediate ones which provide much more accurate estimates and quicker updates. The advanced models are very accurate and can even differentiate between the types of fishes while providing information about their size, depth, and trajectory.
The more advanced ones use GPS where you can save the GPS coordinates of places having more fishes.
