Things To Consider When Buying An Offshore Fish Finder

None of us plan on buying products without having complete knowledge about it. It is better to have enough know-how about the product instead of purchasing a flawed one. There are a few things a buyer should know while purchasing a fish finder. Let us have a look:

Frequency is the main feature by which the device can track down fish under water. It is important to note that having a higher frequency will let you put hands on more fish. It means, the higher the frequency is, the better results you will get. Usually, you will find fish finders with a frequency range of 15, 22, 28, 38, 45, 50, 68, 75, 88, 107, 150 and 200 kHz. All the mentioned frequency ranges can make up a cone angle under water searching for fish. There are different frequencies that work best in varying depth of water. Low frequency works best in deep water, while high frequency is suitable for shallow water.


Power is another important feature to look for. When you go on buying a fish finder, make sure it has more wattage (unit of measuring power) so that it can give you readings as quickly as possible. As the process of locating fish schools is done through sonar waves, it requires continuous and greater power to display results quickly. Besides this fact, you may use a fish finder with less power when you are fishing in shallow water. A general calculation shows that 50 kHz of 100 watts of power can show readings of 400 feet and 200 kHz of 100 watts of power can show readings up to 100 feet. A complete frequency and wattage chart can help you find a suitable fish finder.

Pixels on display

It is in common knowledge to have some pixels on display so one can get a better view of what they are searching. Some pixels will give you more detail on what you are looking for. According to estimations, it is considered to go for a fish finder that has a minimum of 240(v) x 160(h) pixels. This is the least value to be considered otherwise you might not be able to locate fish underwater. The clearer your display is, the better your outcome will be. If you wish to use fish finder professionally, it is preferred to buy bigger screens with excelling screen resolution.


Transducers are the most important feature among all others as it sends and receives sonar waves. It helps in sending sonar waves underwater which is bounced back towards the transducer. It further translates the signals into a more readable content for fishermen. Transducers are to be selected after looking into its cone angle. The beams make up a cone underwater with its wider part reaching the bottom. It is better to go for a 20-degree cone angle that can be used in different depths of water. Also, transducers must be of plastic transom mount transducer material because it is suitable for different depths of water and different types of boats.

This is how you can choose the best fish finder for yourself!
