A sensor helps in shooting sound waves into the water and this is known as as a transducer. This assists in discovering thickness, fish along with the terrain under water. Deciding on the proper fishfinder transducer is a job which needs some basic knowledge on the technique of a transducer, the model of fish-finder and a few simple expertise. A transducer can be attached to a ship in many ways. There are basically two sorts of finders: fixed mount and portable.

Such a piezoelectric transducer is a great boon to all fishermen who want to know what’s swimming under their boats. The technique utilized by means of a transducer describes the benefit provided by one. A transducer helps in converting digital pulses that are emitted by the fish-finder to sound waves which travel down through water. When these waves hit on the terrain or a fish, the echo that is returned is chosen by the transducer that converts it into electronic pulses. The fish finder converts these pulses to a picture. After the pulse has a high frequency, then the resolution of the picture is also better.

Information relating to your fish finder transducer is a small complicated to decipher. Transducers come in both high and low frequencies. 50 to 100 kHz is the assortment of a very low frequency transducer. Lower frequency could be equated to greater depths since the waves in this case might travel for a very long distance. 180 to 200 kHz is the scope for a higher frequency model. 1 important thing to note is that each of fish finders are intended to work only with a certain or a few frequencies. When one intends to purchase a transducer, then one needs to make sure that the model functions together with the frequency of the transducer. This rule applies to both sorts of fish finders.

The sound waves travels through the water in a beam which is emitted in an arc (dimension in levels ). The deeper the beam travels, the wider is the arc. When this is plotted onto a graph, it takes the form of a cone and this can be termed as cone angle. The larger the angle, the wider is the policy area.

While fishing in deep waters, large quantities of water need to scanned in least possible time. In such conditions, the combination of low frequency and wider cone angle is ideal however the resolution of the image displayed will not be crisp.
In shallow waters, the combination of higher frequency and narrow cone angle is considered ideal. A broad cone angle for covering larger area can also be good. It is not as susceptible to outside influences and returns a picture with good resolution.
