The info about fish finder transducers can be both overwhelming and hard to understand. This article lays out your different aspects of transducers while offering some suggestions on the kind of model you may need. These recommendations can be used for both set mount and portable seafood finders.
Transducers come in Lower and High frequencies. Low generally range from 50 in order to 100 kHz. High frequency versions generally range from 180 to be able to 200 kHz. Lower rate of recurrence sound waves can journey greater distances. They permeate further in the water. Reduced Frequency. You need to also remember that fish finder gps combo under $300 are generally made to work with specific frequencies (or a couple of frequencies). IMPORTANT: In case you purchase a transducer separately, or else you already have one, make sure your product will work with the frequency suggestions of your fish finder. This particular applies for portable species of fish finders as well as mounted types.
A transducer works by focusing a sound wave into a ray and emitting this column into the water. This stream is emitted in a small arch(measured in degrees) through the transducer. As the beam moves deeper into the water, the actual arc covers a broader area. If you plot the region the becovers upon graph paper it will resemble a cone, thus the term “coneangle”. If you draw the line from the very suggestion of the cone down to the particular cone bottom you have recognized the center line of the cone. The emitted sound influx is strongest close to this particular center line and reduces as the distance from middle line increases. Cone Position becomes important because the higher the angle the bigger typically the coverage are and therefore the larger the area that the fish locater can “see”. As you shift further away from the center collection, the clarity of the picture decreases.
For shallow drinking water fishing, a high frequency (180 -200 kHz), thin cone angle (20 level – 30 degree) design may be a good choice.You will not be in a position to see great depths, however you’re in shallow water. The narrow cone position will allow you to see things much more crisply than a wide cone and will allow you to be able to differentiate the objects yous ee within the display easier. If you actually want to see a large area, after that think about a wide cone viewpoint instead.
