When choosing a Sonar Best Fish Finder?

With a depth sounder or Fish Finder every angler pursues only one goal: find fish, Casting and catch fish. For the best fishing equipment is useless if the fish is not where you fish straight. The Fish Finder is to help the fishing quota and thus to increase the fun of fishing. The modern Fish Finders provide current even HD images from the nature of the waters reason, the temperature, the thermocline, the depth and whether the fish are at the surface, which means water or on the seabed. This interpretation of the images supplied by the depth sounder is to overcome the problem of most anglers. For a supply sounder not – explicit images from scanned fish, so no one knows for sure what it is because the water is exactly. What counts here is only experience, experience, experience.

What is important?

  • HIGH POWER
  • FREQUENCIES
  • SINGLE / DUAL BEAM
  • DONOR
  • A SENSITIVE RECEIVER
  • HIGH-CONTRAST, HIGH-RESOLUTION LCD

In the quality of the various Fish Finder distinction in the presentation and imaging in the usability and user-friendliness. The technical details, such as some transmitter / encoder / transducer, the transmit power, the resolution of the screen and the width of the swath sonar coverable (Transducer cone) are for the most is the purchasing decision points. Some echo sounders are even suitable for depths up to nearly 1,000 m. Lowrance is for Elite9x- CHIRP Fish Finder on all 914 m depth performance. Where should be clear that in such a depth nothing is to be interpreted fish sickles, because the frequency of 50 kHz does not allow this detail? But should be enough to find fish for interesting sites on the body of water it.

Basics of Sonar Fish Finder

Designed, as we know the Sounders today, was the principle during World War II, to locate the enemy submarines. Sound waves are sent with approximately 1,440 m/s through the water and are reflected by obstacles. The reflected waves are then received and converted into an electrical signal. A fish finder is only one kind of different existing sonar. This is usually a multi-beam sonar. That is, several hundred pulses are emitted by a sensor for measuring consecutively at a distance of about 1.5 °. The Rays do now diverge (fan-shaped), on the way to the base. You form the floor into a width of 30 ° to 150 °. Meet the sound waves on an obstacle; they are reflected upward and be received by the receiver. On the Fish Finder LCD, the current picture can be found on the top right on the display and the history left continuously.

The wattage for the Sonar Fish Finder

The more watts have an echo sounder, the greater the transmission power of the fish finder. Indicated is the power in watts (RMS). RMS stands for Rout Mean Square and represents the average of the output of all frequencies. The wattage shall decide on the number of details that can be displayed on the screen. The RMS specified in sonar is the most important value, since no high-wattage specifications in individual cases (peak to peak), the power can be stable! The expensive sounders such as the Echo lot 598 cxi HD SI Combo Fish Finder have a transmission power of 500 watts (RMS) and 4,000 watts (peak to peak), while cheaper devices like the Lowrence Fish Finder Mark-5x Pro comes to a power of 300 watts (RMS) and 2,400 watts (peak to peak). In spite of the favorable device can send in more than 300 m depth specified by the manufacturer, while the model of Humminbird indicates only 188 m as maximum depth performance.

The frequency in Sonar Fish Finder

The transmitter is located in the water and is down from high voltage pulses in the ultrasonic range. On the way down, the sound waves encounter obstacles such as fish, branches, schools of fish or floating in the water, and things are thrown back upwards, to be received by the transducer. At the latest, when the sound wave strikes the ground, it is reflected the receiver sonar. The software sonar now converts the received signals into an image and displays it on the screen.

Most echo sounders operate at a frequency of 50 kHz to 200 kHz. The wavelength at 200 kHz is much shorter than at 50 kHz (ultrasonic wavelength – 7.5 mm to 30 mm) so that we much more details are captured at 200 kHz than at 50 kHz. Make more sound waves to the object and is reflected upwards to the donor.

Best Fish Finder Tip

If you have any problems at the launch of the operation, then you take a piece of paper and paints on a line of points at a distance of 7.5 mm. Also, repeated the whole thing with a distance of 30 mm. You see that, the shorter distance more details feature (shorter wavelength = higher frequency an echo sounder). Since the wavelength of 50 kHz is larger, the water provides less resistance and to reach a greater depth. Also, one can recognize the soil since the sound waves can penetrate deeper into the ground before being reflected from the substrate. This is important for the so-called Grey Line of the sonar image.

Conventional echo sounders have a price range of at least $250 a Dual Beam. That is that the Sounders transmit simultaneously on two frequencies and thus may represent a more accurate picture. For Side Imaging, you come already approached the $1,200.

The crystal with Sonar Fish Finder

The crystal is responsible for the frequency and the angle of the generated sound waves. The Fish Finder operate at a frequency of 200 kHz and an angle of 20 °. In 10 m depth can thus scan the ground in a width of 3.5 m. The crystal is usually round and electrically conductively coated on two sides and connected to the transmitter. The diameter of the 200 kHz and 20 ° crystal is 2.5 cm.

How is the fish sickle?

These pictures permitted you an idea of how the perfect fish Sickle arises. For the fish must pass completely through the entire beam of the sonar cone. First of all: This occurs rarely. More often, the fish graze the sonar cone sonar or Fish Finder or move in the boat. All these circumstances make the fish Sickle Sonar look different. Either one side of the crescent is shown too thick or thin, or a sickle end is completely missing. The task now is to interpret the fish sickle and make his decision as to whether the fishing spot is worth.

What is CHIRP?

As CHIRP sonar sends the donor not only a sound wave frequency sequentially but simultaneously transmits on frequencies mariner different sound waves toward the ground and may, therefore, represent a significantly more detailed picture, as more information to come back. Works of the Fish Finder with multiple frequencies, the result, is better. As the only CHIRP Echo sounder with two transmitters, combines Ray marine’s Dragonfly Echo gives series the CHIRP channel with another channel for Down Vision what incredibly clear images of the target fish. Otherwise, offer to other manufacturers either a CHIRP Echo sounder or even one with as Down Scan Imaging.

Sonar fishing revolutionized fishing for millions of people around the world. I’m on you ever spent hours at the edge of a river or lake sea wait to catch fish but nothing happens, you come home empty-handed?

Well, with this detector fish, you will find out the best locations.

Your friends will envy you.

Detector awesome fish! If you like fishing, this fish finder that uses sonar technology is for you. You can see on an LCD screen if there are fish in the place where you want to fish

This product is designed for amateur and professional fishermen, to help you find the location of fish including deep water. This device can be used anywhere (ocean, sea, river, lake) it extraordinarily detects fish schools with its sonar.

How does the sonar sensor? Sonar technology is based on sound waves. The system uses sonar to locate and define:

  1. The Structure
  2. The Composition
  3. The Depth

And directly below the transducer with 45 degree coverage. The sensor sends a sound wave signal and determines distance by measuring the time between transmission of the sound wave and the reflection by an object. It then uses the reflected signal to interpret position, shaped and structure of the purpose.
