But don’t bother, these is some components that could indicate you to a perfect fish finder. Like the power, frequency, screen resolution, etc. Here you will find all the important elements need to know before going to Fishing with Spinning Reels.

Choose a Fish Finder Frequency:

Fishfinders come with single, dual or multiple frequencies. Lower frequency like small 50 kHz transducers works fine in deep water whereas higher frequencies, like 192 and 200 kHz work best in shallow water. The higher frequency gives you more details than the lowest one.


Same thing goes to power also; the more power is greater for faster riding. The power measurement unit of a fish finder is wattage. So, if you have low wattage fishfinder then the display reading could be slower and sometimes fuzzier. However, low powered fish finding device could be ok for shallow water. If you are planning to fish in deep water chose the highest power you can. For example,

- 50kHz and 100 watts of power- max reading 400ft.
- 50kHz and 200 watts of power- max reading 800ft.
- 83kHz and 100 watts of power- max reading 240ft.
- 83kHz and 200 watts of power- max reading 480ft.

Screen Resolution:

Screen resolution and screen size an important factor of the display of a fishfinder. Usually, inexpensive units have the smaller screen with fewer pixels. For the crisp and definite view, there is no alternative of high pixels. Start with the 640 x 640 pixel and up if your budget is high and want the best quality of the display.
Moreover, you will found a color or black and white screened fishfinder as well. For any kind of weather/light, colored screen is best to choose.


The transducer sends and receives signal to detect details of the particular area of underwater. Maximum fishfinders unit come with transom mount transducer which requires very easy mount and installation. For advanced one check out thru-hull or others.

Cone Angles & Beams:

Cones are available for transducers in the range of 9 to greater than 60 degrees, but the most units are between 16-20 degrees. The 20-degree cone is ideal for starting for different depth of water. Many standard transducers have a single, dual or double beam. More beams will cover more area which is the great option for lake fish. 

Transducer Material:

There are many kinds of material made transducer are available in the market. Plastic are suitable for almost all type of hull except pontoons. Use-
1.       Fiberglass or wood hulls use bronze housing
2.       Metal or fiberglass use plastic housing
3.       Steel or aluminum use stainless steel housing for in-hull or thru-hull transducers.

These are primary things to consider before buy your ultimate fishfinder. Besides, when you are going to choice, a fish finder look into the size, brand, warranty, services and cost too including above all.
