One of my colleagues was recently confused between choosing Lowrance and Humminbird fish finder. He asked me about some features of the fish finder to make this decision. That is why; I decided to write an article one the ideal features of a fish finder so that you can pick the best one for your fishing finding needs.
Transmitter power is an important consideration while choosing a fish finder. Basically, the more powerful the transmitter, the better the chances of getting return echoes in deep waters. More power helps in producing louder signals, which further helps you in seeing things like fish and bait much clearly.
Mostly, while fishing in not so deep waters, power of the transmitter is not a priority. However, when fishing in freshwater, chances that mud, vegetation and sand will disrupt the signal are quite large so, to considering high power fish finders is important in getting powerful return echo.
Every manufacturer uses a different unit to express the power of a transmitter. Some use watt, while some use peak to peak and Root Mean Square. So, before arriving at a conclusion based on these metrics, it is important for you to understand the actual value of these units carefully.
By now, you have almost certainly observed that choosing an ideal fish finder depends on knowing the exact location where you will be fishing. When it is about choosing the frequency, you will have two options to choose from: 50 kHz or 200 kHz. None of it good or bad but yes, each one of them will have its own advantage. So, it is your choice, which one to choose for your fishing expedition.
The important thing to remember is that you should get high frequency fish finders for use in fresh water as you will have to deal with may hassles on the way in the form of weak or disrupted signals.
The best part of high frequency fish finders is that they render the best detail, produce less noise and work ideally in shallow water. Also, definition of the target is sharper, which means you will get two separate echoes for two fishes on a single screen. Such fish finders work best in 200 feet and below and especially when you are moving so fast.
In some cases, 50 KHz frequency is also preferable. It can penetrate into deep waters just like high frequency fish finders as water absorbs the sound waves slowly in low frequencies thereby, making the signal to traverse fast before losing its strength. That is why; you will find the use of 50 kHz fish finders in many deep saltwater applications.
Since the beam angle for low frequencies is wider it renders a better view of the area beneath the boat. But, this also mean that target definition will be lesser and more prone to noise. So, you cannot expect a good quality picture using these fish finders.
So, before heading to the fishing destination, bear these things in mind to ensure a successful fishing expedition.
