Side scan sonar is one of our areas of real expertise so we insisted on a high quality hull mounted solution with motion compensation to remove pitch and roll artifacts that can be confusing to interpret. The DFF3D is perfect for fishermen, but it is important to pick the right tool for the job. There are three variables that affect the quality and usefulness of side scan images. 

1} CHIRP Side-Scan provides benefits for coastal and offshore fishing that cannot be duplicated with a single frequency traditional fish finder allowing you to see fish targets near piers and bridges before casting a lure or jig.

​

2} Frequency is arguably the most important variable TZTXL users will have the ability to scout fishing locations without scaring fish away due to engine noise or boat shadow in shallow water. Think of a comparison to shing a flash light out from the side of the boat that illuminates the bottom features and anything swimming around in the beam. The higher the frequency the more detailed will be the image but the trade off is range. For example a bass fisherman will want an 800KHz to 1200KHz and you can see the fin structure of the fish. Unfortunately as the frequency goes up the range goes down and these frequencies are only really useful in very shallow water. The DFF3D uses a frequency in the 165KHz range enabling the fisherman to see pelagic fish as ranges of 800 feet as long as the water is deep enough. Any lower than 165KHz will give very long range for the bottom details and features like deep wrecks but we not do much for finding pelagic fish.

​

3} Power. This one is simple the louder the ping from the sonar the further the sonar can see. For the DFF3D a standard is 1KW but this can be extended to 3KW for deep sea blue water fishing.
