How To Find the Right Fish Finder

The most crucial as well as the overlooked part of top rated fish finder is a component called transducer. It is a major part of fishfinding system that you rarely check after you install it and probably you won’t focus on it more unless it stops working. However, it deserves some serious attention when you wish to obtain the best performance of your fishfinder. A few considerations, including particular qualities and mounting location of the transducer, determine how efficiently your sounder performed its work. There are few significant factors to consider while buying a finder


The sensor transmits sonar (sound waves) to illustrate what is under the water surface. The highly important consideration while choosing a sensor is how wider a beam transmitted by the sensor or the cone angle. The greater the angle degree on the cone, the larger your view of what exists beneath. As moving deeper, the angle of cone gets widened. However, sensitivity starts to decrease. Transducers are available in cone angles ranging from nine to sixty degrees, but most units are in between 16 to 20 degrees. A cone angle of twenty degrees is considered as the ideal angle for those fishermen who fish in a range of water depths.

Display resolution

GPS units and fishfinders come in several distinct display resolutions. The more the resolution much better the image is. Color screens are considered better particularly for direct sunlight as you can view them better. High-definition screens are newly introduced to the market, similar to television that offers better image and worth the investment when you can afford it. Display with black and white resolution are yet available and useful when the budget is a restraint. Black and white fishfinder preferable than no other fishfinder.


Size of the display

Display size ranges from 4 to 7 inches and more. As with other marine electronics, try getting the largest screen size that you can afford. For bigger size, you can go with wireless fish finder which will help you to find the fish more efficiently.

Fixed or portable

Fishfinders can be attached either permanently on your boat or can be taken from the ship with ease. Those that rent boats, a handy fishfinder is a right solution. They come in compact size and also with carrying case. Very importantly, they function as efficiently as a fixed unit. Fishfinders in fixed type are probably the best option for boat owners. They can be easily mounted where you want, and the wires can be stored below the floor boards or bow. The transducer can be attached safely to the trolling motor, stem or hull. Portable units make use of suction cup for mounting the sensor.

Ease of use

This is an important characteristic, which is overlooked while buying a fishfinder. Users are focused on the price and making sure their fishfinder comes with all necessary features they need, that they frequently miss considering when the product is easy to use. The best finder that is highly cumbersome or complex will go unused, and you would find that you do not have the time to notice all features that you paid a huge dollar for.
