Fish Finders evolve rapidly and are becoming better and more sophisticated. This is also just a base that allows the operation and understand it useful.

What is a fish finder?
A good fish finder (gauge) is able to measure the water depth, identify the base course and the presence of vegetation, obstacles and fish. A fish finder that provides information only on the place where fisherman with his boat over speed. Purely technical viewpoint, a fish finder is a distance meter: it measures the distance between the transducer and the bottom, wherein each object that is located between them is also recorded.

Why a fish finder?
Did you used to really have a water or continue on information from others, you can now make yourself in this card, or check whether the information is also true indeed. Certainly in great waters, lakes and rivers consists mainly of empty water. By this I mean that space by the fish is used to pull the other one food place and they will rarely longer time. The other part consists of pits, ledges, steep slopes, rocks and branches remains. Precisely these places are a gathering of dirt and food and the places where the fish we want to catch goes in search of food or a shelter and from here goes hunting.

The beauty is that precisely in those places the fish are fairly sedentary or these places come to visit regularly. Big water is also interesting if you buy the best fish finder which also has a GPS function offers so you can exactly find the same place next time, where you can see again, immediately or fish are present and where they are hiding at the moment.

What still does not mean that they bite that day, but you have confidence that you are not a fishless place in the weather?

I write this special "fish we want to catch" because there are of course many other places and situations where there is fish, but for which a fish finder is the ideal tool to locate it. We are thinking of the fish from the shore or in canals and small ponds. But here comes the engineering change thanks to last gadgets such as a fish finder with a wireless miniature transducer is under e.g. can lower the rod tip, or can throw a thread in the water and that you can read the data on your smart phone or your wristwatch.
But these gadgets are currently in their infancy and can not yet compete with the larger models, is already there with the years certainly change. The principle, however, remains virtually unchanged.

Was a depth sounder / fish finder / GPS used to be a luxury product, today there are so many models and brands on the market in every price range that they all fall within scope.
The price is determined by the capabilities such as transmit / receive power, the number of pixels, large screen, 2 or 3d, etc.

Let you purchase also properly informed in a known dealer to avoid a bad buy.

Here also been some technical issues to already have a good idea of the capabilities and operation.

BASIC FEATURES

The microelectronics has ensured that most fish finders placed many additional features. Many of these functions are the essence of the fish have little to do, and are mainly intended to make the whole more attractive to the buyer. We therefore take only the most important features that are necessary, and which are more fully examined present in every fish finder.

Furthermore, you can set different depth scaling (zoom function). For example, from 0 to 10 meters or 0 to 30 meters, etc. In advanced handsets you can even per meter. The advantage is that you get a clearer picture of the soil across the full screen. Another function that goes along with this, the display screen split. This one gets an image on one half of the entire depth, while the other half showing the first few meters from the bottom.
Some sophisticated applications and concepts

Dual Beam PLUS sonar system:

A composition of two sonar beams that function simultaneously. The information of the two beams are combined and (overlapping) appears on your screen. It is also possible to view the information of the two beams side by side or one beam over the entire screen. (chart speed adjustable) Result: A very clear bottom view of planting, structure and / or fish to a depth of 186 m.

If all goes well, and you see a place like the example below, then you're already 100% sure there's fish. Usually you must, however, less clear bottom profiles, do as ramps or depth differences, but it takes you anyway always benefit. One thing, however, you know even with the best fish finder never: if they bite today.
