Buying Guide - Best Budget Fish Finders
To ensure you make your time on the water productive and successful you need to have the right and relevant equipment. It is crucial to purchase the appropriate fish finder and this involves looking carefully at a number of factors.
Type of water
Different water bodies have different types of water. Oceans contain salty water while there are some lakes that have fresh water and some others salty. It is important to identify the type of water you are fishing in as it will impact of your fish finder equipment.
Fresh water has a low density hence low wattage devices are convenient for such water. Salty water on the other hand has a high density hence you require high wattage devices that will be able to transmit sonar waves with ease.
Type of boat
Most fish finders use sonar technology which requires the installment of a transducer on the boat. Some boats lack a transom hence hindering the installment of the transducer.
Furthermore, it is also important to note that some fish finders are not water resistant hence are not good for open water vessels or kayaking and canoeing.
Portability and Time on Water
For short fishing periods it is advisable to use small fish finders that have decent battery life and that are rechargeable. For long fishing periods it is advisable to purchase fish finders that have long battery life and that are rechargeable. For hobbyist fishers who move around a lot then purchasing a portable fish finder will be ideal.
Screen resolution
One important element of fish finders is the display. For you to receive clear and high resolution images you require a display with a good resolution. It is advisable to get 240 × 160 pixels or higher resolutions.

It is important to note screen size also plays a huge role in the amount of pixels the display can accommodate. Good displays give you better detail and crisp images. It is important to note that black and white displays will not offer quality images.
Power and Frequency
Before buying any fish finder it is important to consider the depth of the waters you will be fishing in. for shallow waters, you require a low wattage device and high frequencies of 200 kHz. For deeper waters, it is advisable to buy high wattage devices with lower frequencies.
This is because for deep waters you require more energy for the sonar waves to be transmitted over a longer distance at a fast rate hence higher wattage requirements.
Water Resistance
Most fish finders are mounted on open vessels and this means they are prone to water contact. It is critical and important to consider water resistance so as to prevent damage of the equipment.
How We Tested Fish Finders
It is necessary to regularly check and test your equipment to ensure that it is still operating at optimum levels. You should always test your transducer first.
To test your transducer, install the fish finder on your boat and place the transducer in water so that you can check the transmission of sonar waves. Once you power up the device you will receive information on your screen.

If you are able to get depth numbers that indicates that your device is working. If you don’t receive any data or imagery it means that your device or transducer has a defect. This first step is done in shallow water and with your boat still.
If the first step in successful, you can now start moving. While gradually increasing speed, check your fish finder and see whether you are still receiving data i.e. depth levels and fish location. If it works well while moving at low speeds but not at high speeds then you should make adjustments and do this test again.
Make sure you read your user manual so as to know the location and angle of installment of your transducer so that the test is effective.
Conclusion
When choosing the right fish finder choose one that suits your fishing style. Make sure you consider all the variables such a water type, depth and range. This will help you buy the best budget fish finder that will give you maximum benefit and totally change your fishing experience.
