Fish finders work hard to locate and put over a Big Catch

fish finders are the best tool to use for can find and put your boat on top of fish. All fish finders use sonar to look for water. A sound wave is sent by the detector fish in water forming a cone. When an object is detected, the fish finder that measures the amount of time between when the wave Sound was sent and when they reached the unit and displays on the screen.
If the sound wave does not detect everything touches the bottom. soft bottoms, such as clay absorbs the signal while funds reflect the rock-hard a stronger signal and return. Small differences in reflections on the screen, which shows how the background is playing.
cone angles are the measure of sonar in degrees. Are measured in "-10dB" which is a form of measurement is compatible with the sensor to another and to accurately represent the ability of the fish finder. Each form manufacturer and model different fish cone angles. Humminbird uses an advanced multi-beam which sends 2, 3 or even 6 sonar beams while most makes use of sonar.
Here is a quick reference chart for the area covered by a specific cone angle.
Example: If you are fishing at a depth of 10 feet and a cone angle of 20 degrees, the area where the bottom is 3.5 meters.

20 º -0.35, or about 1 / 3 depth
24 º -0.42 or approximately 5.2 deep
30 º -0.53, or about 1 / 2 depth
-0.72 40 degrees, about 3 / 4 deep
50 º -0.93, Or approximately 9.10 of depth
-1.15 X 60 º depth
70 degrees -1.4 x Depth
-1.48 X 73 degrees of depth
-1.68 X 80 degrees deep
90 º -2 x depth
-2.38 X 100 degrees Depth
-2.85 X 110 degrees Depth

objectives of fish will be displayed as a symbol of identification of fish or a "rainbow" which is a natural sonar returns, the choice is yours. The symbols of identity is determined from a form of suspension is analyzed by the sonar beam to see if a fish. If a fish is detected, seen on the screen like a fish graphic. The arches are shown the characteristics of the probe. Fish that pass through the beam are regarded as an arc on the screen. The unit of sensitivity adjustment, the water depth, boat speed and location of the fish determines the size of the arc.
Clear water, winds or currents can create air pockets and has a lot to do with the signal integrity. small mineral particles, such as algae, plankton and other micro-organisms can absorb sound waves instead of thinking about unity. Wave action will also determine the amount of air into the equation and affect the reading.
Transducers are mounted on the water inside Hull at the motor cross or troll. From a cable connected to the transducer from the fish finder, an electrical signal is taken from the transmitter and converts it into sound. The sensor must always be mounted downward and away from motors or other obstacles.
There are two different types of display screens available. An LCD screen is measured in pixels, the information of the sound. The more pixels no image clarity is better. FSTN displays provide high contrast for easy reading that can be seen from anywhere on the boat. Use technology to grayscale, which provides more detail as shown in the image of her in the shade of gray can easily distinguish what is the fund and what they are fish.

Help depth sounder ... 1980 Hunter 36 'sailboat?

I am troubleshooting my probe. When I bought the boat, which was working intermittently. Now it has completely stopped within a couple of weeks. He has energy, light and alarm works. I replaced the cable ends, but show open to the transducer cables. How do these things? Do you send an audio pulse and measure the water reflection? What I read sensor in voltage or resistance? The sensor appears to be through the hull, is there any way to remove the boat in the water? The knot meter did the same, but I suspect that is mechanical.

Only worked in ours, an S 1978-2. You do not say if it is in fresh or salt water. Never had a problem until she moved the Chesapeake Bay. Most likely through the hull. If you send an audio signal down and measure the time it takes to return. It can be taken when the boat is in the water if you have a wooden plug size hole and insert quickly when the transducer is removed. We checked the continuity of the wires in the transducer, and head. Finally I contacted the manufacturer first ship to his head. It cost him $ 100 to replace two chips and it works again. Everyone told us that should be the transducer, but he said he was the head, and it was. Was reading all the nines. Our knot meter miss a week after the launch of the barnacles.
