Fish Finders - How To Find A Transducer

The data about fish finder transducers could be both overwhelming and obscure. This short article explains the various facets of transducers while offering a few recommendations on the kind of model you might need. The following tips can be used as both fixed mount and portable fish finders.

Transducers are available in High and low frequencies. Low frequencies generally vary from fifty to one hundred kHz. High frequency models generally vary from 180 to 200 kHz. Lower frequency seem waves can travel greater distances. They penetrate further within the water. Lower Frequency = Greater Depth

You have to also bear in mind that castable depth finder are usually designed to utilize specific frequencies (or a few frequencies).

IMPORTANT: If you buy a transducer individually, or you have one, make certain your model works using the frequency guidelines of the fish finder. This is applicable for portable fish finders in addition to mounted models.

A transducer functions by concentrating a seem wave right into a beam and emitting this beam in to the water. This beam is released in a tiny arc (measured in levels) in the transducer. Because the beam travels much deeper in to the water, the arc covers a broader area. Should you plot the region the beam covers on graph paper it may be like a cone, thus the word "cone position". Should you draw a line in the very tip from the cone lower towards the cone bottom you've identified the middle type of the cone. The released seem wave is most powerful near to this center line and diminishes because the distance from center line increases.

Cone Position becomes important because the higher the position the larger the coverage area and then the bigger the region the fish finder can "see". While you move farther away from the middle line, the clearness from the image decreases.

For shallow water fishing, a higher frequency (180 - 200 kHz), narrow cone position (20 degree - 30 degree) model can be a sensible choice. You won't be capable of seeing great depths, but you are in shallow water. The narrow cone position will help you to see things more crisply than the usual wide cone and will help you to have the ability to distinguish the objects the thing is around the display simpler. In case you really need to see a sizable area, then consider a large cone position rather.

For deep water fishing you will likely wish to search the greatest amount of water possible within the shortest period of time. Consider fish finders which have a minimal frequency (50 - 100 kHz) for greater depths, along with a wide cone position (40o - 60o) for greater horizontal distances in the cone center line. This mixture will help you to see at greater depths, however the definition (how crisp the look is around the fish finder's display) won't be nearly as good. You are able to boost the definition by purchasing a fish finder having a greater sensitivity display.

Low frequency, wide cone position setups will have some limitations. For instance, you are able to cover a large area along with a greater depth which will get you in to the "general" section of in which the fish are, but we don't wish to fish within the general area, you want to put our lines directly while watching fish.
