Does a Fish Finders Sonar Shoot Straight Down?

If you have a fish finder, you probably wonder if the sonar will shoot straight down. But if it shoots down in a cone, there is a reason why. The angle of the cone depends on the frequency of the sonar. Those with higher frequencies have a wider coverage area and better detail. fish finders with side imaging

A fish finder’s sonar works on the same principle, which is to send a sonic wave through the water and record it bouncing off of fish. There are two basic types of fish finders: the traditional and the forward-seeing. The traditional style shoots a cone-shaped signal down, while the forward-seeing type shoots a signal in front of the kayak. The returned signal is then processed to produce an image of the fish. The kayak helps reduce the turbulence of the water, which in turn improves the signal’s ability to record data.

Fish finders can come in many different sizes and features. A small, portable model is great for the occasional angler, but a bigger model will give you more details and power. The top-of-the-line models run four to five units with varying functions. However, you must ensure that the device you choose is rigged correctly and has a good battery life. Otherwise, you’ll end up stranded on the water with a fish finder that doesn’t work at all.

When selecting a fish finder, you should pay particular attention to the type of scanning beam that your sonar uses. Wide beam scanning covers a larger area and is good for quickly scanning large areas. It also gives you overall information about bottom structure and depth. Wide beam scanning is best for shallow waters, but may also be ineffective in deeper water.

High frequency transducers use waves at 455-800kHz, while low frequency transducers have shorter wave lengths. They are used to detect fish at shallow to medium depths. Those with higher frequencies have a higher range and will have sharper images. Those with lower frequencies, however, will likely be more sensitive in deeper waters.

Broadband sonar fish finders have a wider range of frequencies. Some have dual transceivers, allowing them to send signals simultaneously on high and low frequencies. The low frequency signal allows them to reach greater depths and have lower noise levels. Broadband sonars will send high and low frequency waves to get a complete picture of the water column.

Lowrance has been around for many years, and the company that is named after its founder is one of the most respected names in marine electronics. The company is known for creating easy-to-use products for anglers. Lowrance has recently added a new forward-facing sonar called Active Target. They also offer HDS graphs in seven, nine, and twelve-inch sizes. Moreover, their DownScan Imaging feature provides 360-degree views of the surrounding water.

A fish finder’s sonar allows a fisherman to focus on the areas that are holding the fish. Without sonar, it is much harder to locate these hiding places. The sonar uses a transducer to transmit sonar signals into the water column and receive echoes.
