How Fish Finders Work

How Fish Finders Work

Fish finders operate under water to map contours, objects, including fish, identify and create an image on the screen everything they find. These are not cameras so the resulting image is not a photo of the scene underwater or video. Conversely, to identify objects with sonar and interpret the scene in technology using a graphical representation. With sonar (sound waves) send signals to the water. When the pulse meets an object bounces off the fish finder. Calculations using the processing and analysis of feedback may useful piece of marine electronics found much information on the special signal objects.

The main components
Sonar consists of two main components, the display and the sensor. The transducer is the power source which emits a beam in the water, returning the processed signal and sends it to the screen. Through a hole in the hull which directly drops the water demand of the tail under the boat, or - The transducer can be mounted directly on the shell.

Understanding the characteristics of the

the angle of taper corresponds to the size of the beam extending beneath the water to provide optimal coverage. Angle in degrees and the objects identified in the cone. A long narrow cone focuses on deep water, while short, wide cone identifies fish over a wider area in shallow water. The spokes may vary from about 60 degrees to 120 degrees. Locate on a multi-beam under different angles of water on the surface and in-depth coverage area at the same time.
The frequency is the power of the measured signal in the sensor kHz. The work for determining the angle of the cone, if the beam can be focused on the deep or shallow water. Lower frequencies, the water penetrates deeper at high frequency (50 kHz frequency is low, while 192 or 200 kHz high frequency).

Imagery
Watch high resolution, sunlight readable display, so it is easy to distinguish the characteristics of strong sunlight. Some fish finders have color displays, while others in black and white. Remember, these are not pictures, but the representations so sometimes it is easier to see the contrast in black and white, but the color can be effectively used for different destinations, such as fish, rocks, etc. distinguish

Integrated Fish Finder
Most people want different components of marine electronics for a variety of different purposes. It may be cheap, fish finder, buy combined with a GPS or plotter. In addition to saving money as an integrated tool has the advantage of less space on the dashboard of your boat.

Buying a Fish Finder Transducer - What You Need to Know

Buying a fish finder can be a daunting task with all the styles that are available, but buying a fish finder transducer is even more difficult, especially since the main features of the information comparing devices is generally less common in the marine industry.

First, you should know that a sensor probe model can come from single frequency and double. The frequencies of the most common operation is 50 kHz and 200 kHz. Models, the higher frequencies (e.g., 200 kHz) to be used with more precision than the unit of the lowest frequency but the same depth of penetration as the model of the lowest frequency. So if you want to go boating or fishing in deep water, you probably want to make sure you buy a converter (single or dual mode with a higher frequency) operating at low frequency.

In the second line of sonar transducer cone is important because it determines the area under the boat, which is covered. Of course, the width of the cone, the larger the area that is covered, and the data can be downloaded from the fish finder. In general, as a general rule, the greater the frequency patterns (more penetration, but none of the more detailed models higher frequency) higher than their counterparts in more frequencies cone.

Finally, you must decide how the transducer is mounted on your boat. Often used as a carrier or carriers (mounted at the rear of the boat) or through the city (welded hull) were sold. While the helmet protects the transducer assembly through the elements and means they are less likely to be damaged, we need a lot more attention to proper installation, and of course the effectiveness of the transducer can be Now pull your look less beam through the boat in the water.

Whatever you choose, if you decide to buy a sonar transducer, which will definitely help you find the fish, making your experience more enjoyable navigation.

Garmin 400C Dual Beam Fishfinder

Garmin 400C Dual Beam Fishfinder Features and Tips

The Garmin Fishfinder 400C is a great fishfinder for freshwater fishing. It can also be used for salt water, but an upgrade to a dual transducer separate frequency necessary. Thanks to its high resolution bright color of this fish finder Garmin screen helps you easily, even in bright sun fish. The screen has a backlight excursions and ease of use for night fishing possible.

Garmin Fishfinder 400C comes with a dual beam 80/200 kHz transducer that allows deep penetration up to 900 meters. (Note that the disorder or covered water can reach the exact depth the fish finder to decrease.) This sensor is best suited for freshwater fish because of its depth of penetration.

The dual beam transducer provides a 45 degree cone fixed to 80 kHz and a cone angle of 14 degrees of adjustment of 200 kHz. This function allows you to see a large area with less depth and will help you get hard to see in the area of ​​fish in the depths.

If fishing saltwater in your future, you may want to switch to a separate dual frequency transducer. The cone angle pi and dual frequency model 1500 penetrate 45 degrees and 10 degrees, depending on the configuration. As in the dual beam transducer, you will see a variety of bottoms, but with this conversion, it is possible, hard to find, see the fish come up to 1500 meters deep.

If you are in freshwater or saltwater fish, Garmin Fish Finder can be a great tool for you.

Remember, however, that this model comes with a dual beam transducer, but you can buy a dual frequency transducer, as you wish.

Fish Finder Advice

There are some things to keep in mind to keep the fish finder screen during cleaning. First, you should make a habit, Fish Finder screen clean after each fishing trip. This good practice, and the following tips to keep in good condition longer.

When cleaning the box (with the exception of the screen) with a damp cloth and mild detergent. Then dry. Do not use cleaners or chemical solvents that can damage plastic parts. To clean the screen, use an eyeglass cleaner and a dry cloth. The reason for using this type of cleaning, because the screen is anti-reflective coating typically has a diameter. ammonia based cleaners, grease, alcohol, or abrasive cleaners to keep glasses clean siding which specifies that harmful use of anti-glare surfaces.

Most fish finders are also waterproof and resistant to it. Briefly under water (see the instructions for your model manual to be sure). Note, however, that the immersion for a specified period (usually 30 minutes) of time can lead to irreparable damage to the device. If submerged fish finder, dry with a clean cloth and let it dry completely before the next fishing trip.

Maybe your style of fishing has changed. Maybe you moved and now the sea or river that are closer. His former fishing equipment can now not be the most suitable or appropriate for the new type of fishing.

If you fish the river, you can stand on the river for a long time trying to catch fish. With a beam of light can make a difference. Maybe you want to sit on the shore all day, then heavy barrel would be more appropriate.


3 If you fish all year round, you may prefer another run at different times of the year. You may need a rental auction, or can be used for the child. Some people like to have a longer rod for fishing in deep water, as it is easier to control. This is especially important when you consider that you can be in the water for several hours.

4 Perhaps you just want to deal with new technologies and advances in technology boom. Many recent advances in technology, fishing rod, fishing and other areas. Maybe you have a lot of fish and a lot of use of their fishing equipment. Do you really need new equipment and a new fishing rod is at the top of the list.

5 When you are too weak, and a fisherman fished for centuries, maybe a new fishing equipment that will inspire. Maybe you've just started fishing, and used an old friend a gun until you have decided that you need to buy your own fishing equipment. Maybe you are old fishing gear stored in the back of the garage for years and spent his best.
