How do you detect fish?

The sonar system acts primarily to locate fishes and underwater structure. Basically, this kind of system applies to a similar approach with the other sonar systems. Their actions primarily include the transmission of sound impulses, measurement of the time for return echoing, and computation of the distance to the objects.

Generally, units categorized under the fish find sonar, they transmit and receive signals in high frequency in every second. Additionally, they focus the sound concentration into a beam that comes from a transducer. This fish-finding sonar unit also contains visual displays that print out echoes.

The fish finder generally detects fishes underneath typically by detecting the air within their swim bladders. Actually, the air confined in this swim bladder alters the path of sound and reflects the energy back. Subsequently, the fish finding tool determines the energy being reflected and converts it eventually into a fish photo displayed on the screen.

Moreover, the photos created on the display are formed via arches through boat or fish movement. Once the transducers send sounds, it is being focused into a beam. Aside from that, the sound goes deep down the water and as the beam distributes out, it generally covers a wider area.

Fish that go toward the cone may generally give off the sound returning to the transducer. The sound returned, or what we know as an echo, shows on the chart of the sonar screen. Additionally, the group of fish will be detected as various shapes or the structure. However, this depends on the amount of group is within the transducer’s coverage.

Further, the creation of fish arch formation began once the fish moves toward the sonar beam. And on the right-side display, a mark basically appears the moment the fish enters the outer part of the cone.

In addition, as the fish goes into the cone, the length between the transducer and the fish reduces. With this, the mark starts to form up a curve. The curve will then form downward once the fish goes further from the transducer. 

What to look for when buying the best fish finder for bass fishing

Here are the following things that you must consider when you want to buy the best fish finder for bass fishing:

✔ Mounting ability – portable vs. fixed

Further, lots of updated models nowadays already have GPS integrated inside. Moreover, those devices with GPS are generally combination models. Fishing tools with this feature work well on chart plotting and depth sounding.

Additionally, fish finders with GPS are capable of entering various waypoints. Having this, you can mark various structures, ramps, and fish. It is generally important to remember this feature as it is an important one to look for a fish finder for bass fishing.

✔ Scanning

Basically, there are two methods on how scanning works on the best fish finder for bass fishing. These methods include the downscan and sidescan.

A downscan generally permits the user to identify excellent detail and spot fishes. These types of scanning sonars give more accuracy. However, they are usually more powerful within shallow waters.

Moreover, the sidescan allows the scanning of sufficient amounts of water that covers a bigger area. Additionally, you are not required to move the fishing vessel directly to the fishing area you are scanning. Aside from that, with the sides, the best fish finder for bass fishing can also scan calm water. 

✔ Transducer

Basically, the transducer is the fish finder component that acts to transmit sound waves. This generally offers an idea regarding underneath lurking within the water’s surface. The transducer generally performs similarly with a radio antenna as it produces sound waves and gets back echoes.

Moreover, a transducer can be mounted in various locations that permit its sitting in the most convenient part of the best fish finder for bass fishing. The location of the transducer is basically on the trolling motor or transom or at the inner compartment of the hull. 

The transducer choices generally vary on the cone angle, that’s why it is better to opt for the best fish finder for bass fishing that compliments well with bass. Always remember that transducers having wider angles are basically less effective in deep water. Meanwhile, it provides wider imagery of the shallow water.

✔ Display

Another great feature of the best fish finder for bass fishing is the display. It works basically in the same way an underwater camera operates. When looking for this feature, focus on the size of the display, its color, contrast, and details. 

Moreover, another important aspect for consideration in terms of the display is the count of pixels. It is also a generally important concern to know that the more pixels the display offers, the clearer and smoother the image will become. In addition, a large size of the screen also elevates the ease of reading.
