Garmin striker 7sv Fish Finder – How to Choose a Transducer?

The data about fish finder transducers can be both overpowering and hard to comprehend. This article spreads out the various parts of transducers and offers a few recommendations on the kind of model you may require. These rules can be utilized for both fixed mount and compact fish finders.


Transducers come in Low and High frequencies. Low frequencies by and large range from 50 to 100 kHz. High recurrence models for the most part run from 180 to 200 kHz. Lower recurrence sound waves can travel more noteworthy separations. They infiltrate further in the water. Lower Frequency = Greater Depth  You have to likewise remember that fish finders are commonly intended to work with explicit frequencies.

Cone Angle

A transducer works by concentrating a sound wave into a shaft and producing this pillar into the water. This bar is radiated in a little curve (estimated in degrees) from the transducer. As the pillar ventures further into the water, the circular segment covers a more extensive region. On the off chance that you plot the territory the shaft covers on chart paper it will resemble a cone, along these lines the expression cone point. In the event that you draw a line from the very tip of the cone down to the cone base you have recognized the inside line of the cone. The produced sound wave is most grounded near this inside line and lessens as the good ways from focus line increments.  Cone Angle becomes significant in light of the fact that the more prominent the edge the greater the inclusion region and in this way the greater the territory that the fish finder can see. As you move further away from the inside line, the clearness of the picture diminishes.

High Frequency transducers accompany either a thin or wide cone point.

For shallow water fishing, a high recurrence (180 – 200 kHz), tight cone edge (20 degree – 30 degree) model might be a decent decision. You would not have the option to see incredible profundities, however you’re in shallow water in pyrogadget. The restricted cone edge will permit you to see things more freshly than a wide cone and will permit you to have the option to recognize the items you see on the showcase simpler. In the event that you truly need to see a huge territory, at that point consider a wide cone edge.  For profound water fishing you will no doubt need to look through the most elevated volume of water conceivable in the briefest measure of time. Consider fish finders that have a low recurrence (50 – 100 kHz) for more prominent profundities, and a wide cone point (40o – 60o) for more prominent even good ways from the cone place line.
