In these cases, they do not need highly upgraded fishing finders. The water is not so deep, and one can do with the ones who come at a lower price. In other cases, people may go out for fishing in the coastal regions, which need different criteria, according to the various situations they face. Fishing in deep seas is a different story after all, and one needs different features in the best fish finders. Before purchasing a perfect unit, it is wise to be specific of its use, so that the perfect degree of customization can be achieved. Broadly speaking, there are three different kinds of fish finders-:
Standalone
This is the cheapest one, which is used in lakes and small water bodies. These are not technically upgraded, and allow one to see what is just below the surface of the water. It is not rich in great features, and if the budget is low, this one serves ideally to the fishermen. Later on, one can always add a GPS to the system, which makes it more useful when it comes to finding the fish. It is used by the people who fish in shallow waters. These do not provide ideal services in deep waters.
Combo
These are more upgraded than the standalone wireless fish finders. They come handy when people go out fishing in medium sized boats and in comparatively greater depths of the seas. Fish finder combo is powered by the GPS system and come handy to fishermen in deeper areas. The chart plots of the combo units can be turned into combo units by the black box. Apart from that, it can be viewed on split screen as well. All these features make the device ideal for mid-range fishermen.
Network

Display
This is very important part of this device that is displayed. The user has to check the display while fishing because it can help you to see the location of the fish in the water and one more thing the size of the display must be good so that it helps the user to see clearly the location of the fish in the display. That is the reason this is one of the most important things which the user has to check while purchasing the depth finder.
Resolution
This is another thing which is also important for the display and that is the resolution of the display. If the resolution is not good then if the display is there it is useless for the user because the resolution is the only thing in the display which helps the user to see the clear location of the fish in the water. That is why the resolution is the second most important thing which the user has to check while purchasing the best selling fish finder.
Capability
This is the thing which is also important for the user to see the capability of it and it means how depth the sophisticated fishfinder can go. The user has to choose the best depth product so that he can easily see the fish in the very depth of the water. This is also one of the important things which the user has to see in the product while purchasing it.
Size and Weight

The Useful Fish Finder Guide
To select the right Fishfinder is not a child game. The anglers have to keep in mind various factors such as the size of the device’s footprint, resolution of the display, how much the transmitting power needed and many more factors before opting for the Fishfinder.
- Includes transducer for built-in Garmin CHIRP traditional sonar plus CHIRP clearer scanning sonar
- Built-in Garmin quickdraw contours mapping software lets you create and store maps with 1’ contours for up to 2 million acres
- Built-in GPS lets you mark waypoints, create routes and view boat’s speed
- Bright, Sunlight-readable 5” display and intuitive user interface
- Rugged design for every fishing environment
Colors, size, and pixel quality
The pixels, colors and size quality matters while buying the device. The higher the pixels in vertical direction leads to higher depth resolution and more horizontal pixels for how long duration the object will be displayed on the screen.
Diagonal dimension matters
Diagonal dimension of the screen size matters a lot in deciding the ground breaking fishing device. Big screen leads to the display of more substantial details.
Different Frequency amounts
The user must not overlook the frequency factor because the higher frequency rate leads to the display of more details onscreen. Frequencies come in various ranges such as dual, single and multiple. Higher frequencies such as 192 and 200 KHZ are not for deep water.
Power
Power also plays a significant role while choosing a fishfinder electronic device. The power of this tool measures regarding watts.
For the faster and the deeper display of the information, the amount of the watts must be higher. The low watts lead to the slow display of the readings.
The reason behind the slow reading is that if the power is low in watts the sonar waves will be slower and as a result, the reading will not be clear.
Transducers
Transducers are the backbone of the best fish finders; these are the primary source which releases and receives the sonar waves. The Transducers send the sonar waves into the water, which in turn when strikes the fish bounce back the substantial details, such as the size, composition, and shape of the fish. The information is received by the transducers, they send the picked data back to the main unit, which converts the language of signals into pictures for the easy understanding of the user.
The working of the Fish Finder For Fisherman
The main aim is to recognize the different objects such as rocks, fish, etc.; under the water. The technique that this smart, user-friendly instrument follows up is the sonar technology. The word “Sonar” stands for sound navigation and ranging. The primary principle that implied in the sonar technology is that noise in water or any other medium travels at a uniform speed, and when the sound reflects back from an object, the distance of the sound can be easily traced out with the help of the sound‘s speed.
- HOOK2 5 - 5-inch Fish Finder with TripleShot Transducer and US Inland Lake Maps Installed
- EASIEST TO USE: The Lowrance HOOK2 5 Fish Finder features auto-tuning sonar and phone-like menus giving you more time to spend fishing and less time dealing with settings.
- WIDER SONAR COVERAGE: The HOOK2 5 offers a wide-angle CHIRP sonar cone giving you double the coverage of traditional fish finders.
- EASY SETUP: A single transducer can be mounted on the transom, inside the hull, on the trolling motor or through a scupper hole. The HOOK2 5 is ideal for small fishing boats or kayaks with limited console space.
- MORE SONAR VIEWS: The Lowrance HOOK2 5 comes complete with a TripleShot transducer which gives you DownScan sonar (straight down), SideScan sonar (up to 300' to each side), and CHIRP sonar (fish arch) views.
Not only the distance, but even the nature of the object can also figure out by just calculating the variation in frequency in the reflected sound. In the same way, our very own fishfinder operates, the device releases the sound waves beneath the water and on striking any foreign object these waves transmits the signals back to the fishfinder unit. By the calculating the amount of time between when the sound wave was sent out and when it reflected back to the unit the user can find out the distance and shows it up on the display screen for the user’s conveyance.
It has two important sections namely the display screen and the transducer. Any superior quality fishing finder is worthless without a brilliant sensor. As far as the working of the transducer is concerned, the transducer receives the electrical signals from the transmitter and convert it into sound and releases it out and at the same time receives back the coming sound echoes and turns these echoes back into the signals. The transducers are connected with the help of a cable.
The selection of the transducer depends on its operating frequency, cone angle and kind of installation done. A transducer‘s cone angle calculates its coverage area beneath the water, hence broader the cone angle; the larger area does the transducer occupies underwater. The transducers with the frequency rate of 192 or 200KHZ come under the higher frequency category which is brilliant while navigating through the deep water. The higher the frequency rate, the more information is displayed on the screen which is of great help to the user as he can pick up the details of his use easily and fetch his fish effortlessly. There are different types of transducer installations such as Transom mount, shoot –thru-hull mount, Bolt-thru-hull mount and trolling motor mount.
- Includes transducer for built-in Garmin CHIRP traditional sonar plus CHIRP ClearVü and CHIRP SideVü scanning sonars

- Built-in GPS lets you mark waypoints, create routes and view boat’s speed. Transmit power - 500 W (RMS)
- Bright, sunlight-readable 7” display and intuitive user interface
The LCD screen of fish finder is the second most valuable component of the unit. The display screen shows up the sonar information. The LCD displays are calculated in “pixels”. The higher the pixels rate, the better resolution, and high-quality clear pictures do it provides to the user.
Apart from the above two parts the other factors that affect the working of this electronic device are
Cone angles
The cone angle as the name suggest is the angular measurement of the sonar beam in degrees. Different units have different cone angles most of these units come with single sonar beam except the hummingbird model having advanced multiple sonar beam feature.
Sonar beam coverage area- this is the area covered by the sonar beam.
Fish target
Fish targets can be shown up on the screen by opting for any one of the two methods namely “arch” which is an unprocessed sonar return or a fish ID symbol
Water quality
The intactness of the sonar signals depends on the quality of the underwater. High waves can disturb the signals, even the foreign particles such as algae and other microorganisms that come in the way of signals can have an adverse effect on the signals.
Thermocline
There are many fish Finder in the market which includes the thermocline trait. The primary function of the thermocline is to display on the screen the change in the water temperature and thus make the fisherman aware of the exact water temperature and help him to locate his targeted fish easily since some species of fish are found in hot water while others are available in cold water.
