Yahoo! I got the fish!!! That’s the wish line to utter by every angler from ages.
Some time ago, anglers used to ask from the pro and veterans about the area in the water where the significant number of fish is present.
People are a firm believer of the fact that the honesty of old anglers is almost of the same level as that of politician, insurance agents and estate agents have.
With the intervention of technology, this old school methodology for the sake of confirmation of the presence of fish is now outdated.
Nowadays, people use portable fish finder sonars and fishfinder HD cameras with display units to verify the actual location of fish and the exact structure of the under-water surface.

Buyer’s Guide: Choosing the Best Portable Fish Finder in 2021
There is a wide range of fish finders based on sonar system, and price varies depending upon their features.
For the selection of the best fish finder, some factors are the basics that an intended buyer should consider. It will help to make a well-informed decision that will value of money spent.
Price is the primary essential factor when you are going to buy a fish finder. While finalizing one for yourself, you consider whether is it under budget and meeting all my requirements.
Of course, no one will like to go for the product that is economical and lesser than the budgetS you have for this but do not meet the requirements.
On the contrary, you will not buy a product with features, but of price beyond your budget extreme, as you will not like to pay for the elements, you are not going to use.
The transducer is another basic unit which is the backbone of every fish finder. It sends signals to find out the fish and structure of underwater earth.
Transducer part can be either mounted on the boat’s transom or with a motor of fish. Installing with trolling motor may affect cause interference.
Sometimes transducer thing can be connected with the hull of the fish. However, portable transducers are the best option where you don’t want to install them just cast them in water and then you need to wait and watch.
Angle of Sonar:
The angle of transducers with which sonar goes down is another decisive factor in the selection of fish finder. Angle ranges from 9 to 60 degrees.
There is a conceptual trick while taking the angle of the sonar as a critical factor. The sharp angle will go deeper in the water, and it will give the crispier results, but it will cover a lesser area under the water.
On the other hand, a wider angle includes more space, but it provides blurry information and does not go deeper in the water.
Multiple conical angles are sent down the water in modern fish finders.
The signal frequency ranges from very low of 50 kHz to a high frequency of 200 kHz. The higher the level of frequency is associated with sharp angles beam that can go more in-depth and gives precise results.
While in the case of low-frequency transducers produce the wide-angle sonar beam that covers more area but does not go deeper in the water.
Transducers do not send signals straight downwards in the water. It may be directional, provided messages are powerful, and water is shallow.
Power of Signals:
Wattage is the measuring unit with which transducers send a signal into the water. The more be the wattage deeper be the penetration of signals down into the water.
For a shallow water fishing watts of 200units will be good enough, 500watts shall be good to go for coastal fishing. If you are angler of deep blue waters, at least 1000 watts are required to start the game.
To read the signals received from the transducer display unit shall be required, which is another countable factor. Options of the grey scaled screen and hi.res screen in variable sizes are the option for output unit.
These output units come with different features regarding output presentation, which angler has to decide which is useful.
Some fish finders come with alarm beep which gives its audio whenever sonar waves strike with fish. However, this feature becomes annoying if it gives you a lot of false signals, without correctly differentiating between fish and non-fish items down the water.
Some advanced fish finders also offering GPS, which helps you in a boat fishing and mark the waypoints for future reference.
Durability is the characteristic feature for every kind of product which you purchase. In the case of fish finders, it will be considered as durable, if the product is waterproof and weather-resistant.
For the anglers of blue waters or salty waters, the corrosion-resistant fish finder will be the choice of course.
The warranty period should be count in a while, deciding on the purchase of anything.
Different well-known brands are in the business of manufacturing of fish finder. A brand is well known or of good to go with if it keeps updating its product with better features.
In the comparison of the two fishfinders selection should be of the well-known brand as some level of user’s trust is higher in such cases.
Still, you are no need to get confused with so many numbers of factors to be considered.
What all you have to do is, to consider your available budget on the first instance. Secondly must know the brand you are going to purchase.
Then, focus on the features you need and match with available items and then boom.
You are good to go with your selected product.
Best of luck and have fun. Stay blessed and blessed with fish as well.
