Sonar Fishfinder GPS Marine

A friend of mine was recently the choice between Humminbird fish finder and Lowrance fish finder. He asked me several features fishfinder. So I chose to write this article on seeker functions you can watch the fish when you choose your ideal. If you are interested in finding other properties of fish you might want to display, you read my previous articles fishfinder.

POWER

transmission power isimportant when choosing a fish finder. In general, the stronger the transmitter, the greater the likelihood of a return echo in deep water or less than optimal water conditions. Basically, it generates a higher signal, you may see things as bait and structures in detail the better.

If the majority of fish in shallow water, then emissions will range finder at the top of your priorities for a fish. But on the other hand, evenIf you are in freshwater fishing, there's a good chance of sand and vegetation on the bottom of the mud absorb and scatter the sonar signal, reducing the strength of the returning echo. In other words, is better in a situation where you can just dial back the amount of power you need, rather than not enough Have power when you need it.

Fish Finder manufacturers to push the transmitter power in watts, but some use the term peak, "a peak", while others useRMS (Root Mean Square). "Peak-peak" may be somewhat misleading, because it is basically a number of high numerical values instead of RMS, based on an average. So do not assume that a high peak to peak rating is more powerful than a lower score indicated as numbered RMS.

FREQUENCY SONAR

By now you probably noticed that your fish finder is entitled to know where you will make the most of your fishing. When it comesthe frequency options, two options is 50 kHz or 200 kHz (some manufacturers will have to 192kHz but basically there are no "low" and "high"). Each has its own advantage, and it is up to you to decide which option is best for the type of fishing you do.

The rule of thumb when it comes to the frequency sonar is the application of high frequency (192 kHz – 200 kHz) for fresh water, because normally focus primarily in shallow water.
In general, higherFrequencies provides the best detail, shows generally less "noise", and works best in low water and high speed. definition of objectives is also sharper with these higher frequencies. This is the ability of the two fish as two separate echoes instead of a single mass on the screen to show. In short, it works well for depths less than 200 feet (60 meters) and if you try to impose an accurate reading while moving faster.

There are some applications where a frequency of 50 kHz is preferable, however. 50kHz sonar (under the same conditions and current) can penetrate a water depth greater than the higher frequencies. This is because water absorbs sound waves at a slower speed for low frequencies and the signal to travel further before it is too weak to use in order. Therefore, you usually find less than 50 kHz used in salt water.

The viewing angle is also typical of large low-frequency sonar pulse output is another means of cone and 'best display of alargest in the area under the boat. However, this means a smaller and more sensitive to noise. Despite the low frequencies can see deeper, you can not give a clear picture of the bottom.

If you think you are fishing in freshwater and saltwater environments, you will find fish finder that allows you to change the kHz best of both worlds, providing Frequencies 5-20 kHz. Be prepared to shell out more money but.

TIP: Do notForgot your partners that the transducer frequency sonar unit. Simply can not with a transducer of 50 kHz or 200 kHz transducer on a sonar device designed only for about 192 kHz or vice versa.

A converter must be able to withstand high transmitter power impulses, converting as much of the boost in sound energy as possible, while sensitive enough to get the faintest echoes. Choose wisely and do not be afraid to ask questions.
