Best Fish Finder 2023- Unbiased Reviews & Buyers Guide

by | Last updated Mar 27, 2023

How Fish Finder Works?

A fish finder does not have a complicated way of operation. An electrically compelling force from a transmitter is transformed into a sound wave by an underwater device that is used to convert energy from one form to another. This device is known as a hydrophone. Reflection of the wave is made when the wave strikes either a fish or debris and the reflected wave produces the size, composition, and shape of whatever it comes in contact with. The exact extent of what is obtained is dependent on the frequency and strength of the compelling force that is transmitted. To locate the precise position of fishes in the water, a fish finder has a high level of sensitivity of temperature and pressure. Modern fish finders have trackback that is capable of checking and changing movements with the aim of changing position while fishing. Better details are produced on the screen when the fish finder frequency is high. Commercial fishing involves the use of low frequency while modern fishfinders make use of high rates to view results.

What is a Fish Finder? 

A fish finder is an equipment used to find the location of fishes beneath the water by discovering reflected pulses of sound strength. A typical fish finder shows the measurement of sounds that are reflected graphically thereby allowing an operator to understand the information on locating underwater debris and fish schools. The fish finder equipment is used both in sporting and commercial activities. A modern fish finder can be linked with marine radar compasses and global positioning systems (GPS) as a result of advanced technology.

The word fish finder is derived from the phrase Fathometer, and a Fathometer is a device or equipment that is used to measure the depth of a water body. This equipment can display the water depth and can also keep a record of measurements automatically. Hence, since both the fathometer and fishfinder work similarly, both were merged.

Buyer’s Guide

Fishfinders vary in design and makeup. To make the best decision when looking for a fish finder, the following factors should be taken to heart. These factors are discussed extensively below.

2020 Guide to Choosing the Best Fish Finder Under Budget: 

  • Transducers: It is the part of a fish finder that releases and receives sonar signals from beneath the water. Each type of fishing requires a sensor, and the transducer for various fish finders differs in signal strength. When fishing in a sea, a fisherman would need a transducer that sends a signal to very great depth while if a fisherman is catching in a river or a smaller body of water, he would require a sensor that transmits sound waves to a wider angle. A purchaser should also give attention to the amount of frequency a transducer operates on. A transducer can be installed on a transom or the trolling motor depending on the boat. Although, portable transducer does not require mounting.
  • Cone Angle: The cone angle has to do with the range or depth a signal can get when deployed. The truth is the deeper the water, the wider the cone angle would get beneath the boat. A cone angle can range from fifteen to twenty degrees while some other cone angles can reach as full as sixty degrees. Most fishers usually use fish finder that has more than one cone which helps them cover large angles while remaining at a spot.
  • Frequency: When a fish finder produces a high frequency, there would be more information transmitted to the user’s screen. High frequencies produce better results in waters that are not deep, but fishers that are into commercial fishing makes use of low-frequency fish finders. A lot of fish finders have more than one frequency, and frequencies of 50 to 200 kHz are most common.
  • Display Screen: Newly produced Fishfinders make use of color screens which has a better advantage to the traditional black and white screen because it provides clear pictures. Colored screen fish finders are affordable because they are becoming the norm and are replacing the black and white screen fish finders. The screen resolution should also be taken into account. Screens that are large makes it easier to point out the exact location of areas and structures. The lowest recommended screen resolution should be 240 by 160 but to enjoy the reading on the screen, a person can decide to take it much higher.
  •  Power: For a sonar to operate effectively, the power must be high. A fish finder’s strength is measured in wattage, therefore the higher the wattage, the faster the relaying of results to the user. Generally, a fish finder can display readings that are up to 400ft per 100 watts at a frequency of 50 kHz. If working at a rate of 200 kHz, a person can be able to count on readings of a distance of 100ft for every 100 watts of power. Thus it is advisable to consider the wattage of a fish finder rather than the range based on frequency.
  • GPS Capability: For a fish finder to be regarded as the best, it must have GPS capabilities. It would not be wise to purchase equipment separately for navigation when a purchase can be made for stuff that has both fish finding and navigation together. Fishfinders with GPS help the user to save spots that are of interest to him or areas that have submerged factors.
  • Scanning: There are two ways a fish finders scan. Either down or side. The fish finder that does down-scanning is more powerful and useful, but they can miss things not passing directly beneath the user boat. The side-scanning fish finders can scan a significant amount of water but are not effective in deep water. So when purchasing a fish finder, consideration should be given to an area of concentration. So it is advisable to make use of or buy multiple fish finders.
  •  Portability: Due to certain conditions or situations, a portable fish finder is preferable. In recent times, this type of Fishfinder has become much popular. If fishing is done on a small boat, it is good to make use of portable fish finders. Using the portable fish finder is simpler. It is used by casting the transducer into the water, and the result would become visible on the users’ mobile device such as a smartphone or tablet. If fishing is done on a lake or pond, portable fish finder works better there but fishing in an ocean or a very vast body of water, it is advisable to stick with the traditional fish finders.
  • Design & Durability: Most people give negligence to the build and design of a fish finder. But the shape and the way the buttons are placed is essential. A durable fish finder should be rated as waterproof or water-resistant. Since salt is a very corrosive element, if a person would be fishing in saltwater, then Fishfinders that are built to prevent corrosion should be used.
  • Price: Although it is not advisable to buy anything just on the price alone, attention should also be given to the price tag. If a fish finder has all the needed and necessary features, then it should be more expensive than an entry-level model of a fish finder. Also, it is of no use to empty a wallet if only one requirement is needed for a fish finder to be purchased. Therefore, a buyer should buy what he or she needs because in most cases, those extra features found in a fish finder can be very complicated and frustrating. Always compare prices by visiting different outdoor suppliers and make comparisons by going online also. If a lower cost of a fish finder has been seen, then it is right for the person buying it to check if it is the right model and the same warranty.
