All fishermen, leaving to catch fish, probably, would like not just to derive pleasure from the process but also and to come back with a catch, and the big, the better. In modern times the set of devices which help to increase the fisherman’s catch is constructed, and one of them is a Fishfinder. This device which allows scanning not only a bottom or a relief of a bottom but also objects which are in water space including fish. Undoubtedly, Fishfinder will not catch fish for the fisherman, but he can prompt large congestions of fish or a hollow and a hole where it is possible to catch larger fish.
If the fisherman knows all most fish places, then Fishfinder to him can and not especially would be useful, but if the area is unfamiliar, then Fishfinder is irreplaceable, and especially in the summer time of year when there is an opportunity freely to move on a water surface by boat, scanning a bottom.
Choosing Fishfinder for fishing, it is necessary to approach this business very attentively and circumspectly, having studied at the same time all properties which are possessed by this device because it can play a huge role as all catch.
Presently there is a huge variety of specialized fishing shops where it is possible to buy Fishfinder which also has a set of modifications and producers. At the choice of Fishfinder it is necessary to pay attention to properties which it has to possess:
1. power of the transmitter;
2. size and quality of the image of the screen;
3. whether the receiver is sensitive to ultrasonic waves;
4. efficiency of the converter of waves which transfers information to screen;
5. quantity of beams;
6. compliance of cost with a reliability of brand of Fishfinder.
As a rule, there are Fishfinders and with different corners of ultrasonic waves. The corner is wider, the quality of scanning of a bottom is less. The Fishfinder with a small corner of radiation as it is already possible to move freely on a water surface by the boat in the summer will be suitable for summer fishing and at the same time to have the qualitative picture of the image of a bottom. Therefore it is not obligatory to choose fish finders with a wide-angle range which, usually more expensively. But the most important task remains, nevertheless studying of properties of Fishfinder then the choice of purchase of this or that model will be made.
One of the major parameters the transmitter power which just and defines a quality of the picture of a bottom on the display is. At ultrasonic waves reach to the bottom and, being reflected from it come back to the receiver. Therefore if the power of the transmitter is too small, and reservoir depth very big, ultrasonic waves can just not return back and the picture on the display will not be.
The buyer has to choose the screen size itself, arranging under the sight, but at the same time, it is necessary to check also a quality of the image. Often happens that at an increase in the size of the screen, quality of the image, with an increase in pixels decreases.
As well as the transmitter power, sensitivity of the receiver plays the major role as the image of a bottom, therefore, it is necessary to pay attention to this property.
Similarly, it is necessary to define whether the converter qualitatively works. The converter processes data, the beams reflected from a bottom and transfers them to the display of Fishfinder in the form of the picture. Or converters work at various frequencies. It is necessary to understand that than frequency is higher, to that the picture will be the most distinct, but a depth of scanning will be less. If frequency small, then the quality of the picture decreases, but a depth of scanning of Fishfinder will increase. Here to choose to the buyer.
The quantity beams in Fishfinders of various models can be miscellaneous. The more beams give the Fishfinder, the big area of a bottom it will be scanned at the same time. But the price at Fishfinders with a large number of beams will be much bigger.
At compliance of the price and quality of a model, it is better to choose models of more popular brands which already proved in the market. As durability of the bought equipment can depend on it.
On Fishfinders, as well as on other equipment give a guarantee therefore as soon as possible it is necessary to check it for all properties.
