fish finder faq

What is a Fish Finder?

Whenever they hit something harder than water, they are reflected and received from a station again on sonar. Based on the time it takes for the individual waves can then distance determined very accurately. In this way, anglers know how deep the water among them. In addition, however, other irregularities are determined. The Fish Finder uses the technology of sonar. This was originally invented during World War II to find enemy submarines. The device sends for ultrasonic waves, which move at more than one kilometer per second through the water.

The fish finder prepares the information on a graph, which is usually displayed on the integrated display. However, this is not obvious where exactly are fish, but only approximate values concerning the established irregularities. Larger accumulations of dense objects on the seabed may, for example, be an indication of a shoal of fish.

How to Find the Best Fish Finder?

With so many fish finder brands, models, and types on the market, it can be very time consuming finding the right one. This site is designed to reduce that time spent searching and help you find the right fish finder for your boat and style of fishing. Fish finders are an expensive item, so it’s important to do your due diligence before buying. Take some time to read the fish finder reviews and comparison charts provided on this site before deciding…

What is a Portable Fish Finder?

Portable fish finders are electronic devices that provide assistance in catching fish. It is not necessary anymore to spend hours on end trying your luck in waters that may be empty of any fish. With this unique and useful device, you can save a lot of your precious time in scouting for fish and can straightaway proceed to the task of fishing. This device works on the basis of radar signals that enable you to zero in on the exact position of fish in the surrounding water. You can also get a clear view of the ocean bed thus making your fishing activity even more efficient. These devices are available in a number of different shapes, sizes, and designs and come packed with diverse features. This can sometimes make it difficult to make a choice that you are satisfied with. Following are some of the guidelines that can help a discerning customer in making an informed decision that he/she will not regret later on:

  1. The first thing that one needs to decide first is the amount of money that one is willing to spend on a portable fish finder device. The budget must be kept strictly in mind and only the models corresponding with the budget should be looked at so that you do not end up spending well outside your limits.
  2. You should check the clarity of the display screen before you make your purchase. Many new models are now equipped with screens that offer very clear and sharp views and this aspect must be explored before you make a choice. You should not buy an electronic fish finder before asking to see the display first-hand.

Which is Right for You Portable or Fixed?

Fishers have the choice of buying a fishfinder that will be attached lastingly to their watercraft, or one that could be taken out the craft without breaking a sweat. For those that lease watercraft, ice fish, or head off to places to “fly-in” fish, the portable choice is the one to engage with. Settled fishfinders unquestionably get approval for watercraft owners, as they could be mounted in the precise location they seek. The transducer can likewise be affixed to either the stern, trolling engine or hull – providing the fisher numerous choices.

How does sonar work?

Sonar works by conveying an electronic impulse from the device to the transducer. This urge is transmitted into a sound wave by the transducer, at which focus it is channeled through the water segment. The sound wave will now move into a descending manner until it achieves the lowermost structure – it is right now that it will rebound to the receiving device. The sound wave will likewise “travel” through any items discovered between the lake bottom and the surface of the water (fish or baitfish). When the indicator is gained, the device will then create its readings, at long last illustrating the outcomes on the screen.

What is a Depth Finder?


You want fishfinders with a low frequency, which usually means 50 or 83 MHz. If you happen to be one of those lucky guys or gals who gets to fish in both shallow and deep waters, get a dual frequency finder, which will work anywhere your boat goes.


You need a lot of power to fish significantly more than 100 feet beneath the surface, meaning your finder should possess between 250 and 500 Watts, RMS.

Cone Angle

Deep-sea fisherman should use a narrow-angle cone because it has sufficient resolution in deep water to see your potential catch. Better yet, get a transducer with multiple cones if you can afford it.

Depth Finder Features

Screen Resolution and Size

The more the merrier. Get the biggest screen with the best resolution you can afford. A beautiful, large, high-res screen will enhance your fishing experience, and isn’t that the point? Furthermore, that gorgeous fishfinder might even help you catch a few more fish. You can even use that as an excuse when your spouse confronts you with the credit card bill. Unless you are short of money or you need a more compact portable fish finder. Please let us know how well that works out.

Color Versus Black and White Screens

Get a color. It’ll be hard to find a black and white screen, anyway.


Most modern fish locators come with that, as well they should. This device shows waypoints, which mark navigation aids or your favorite fishing spots. They’re also compatible with charting packages, allowing for detailed mapping. Even if you have a primary GPS on your boat, a backup on your fishfinder won’t hurt. Also, don’t forget that you can use two GPS units for different charting packages.

Specialty Items

You can now get fishfinders that will do everything, but take out the garbage. High-end devices will measure surface speedwater temperaturebarometric pressure, and various other things. Some of this data helps anglers who troll and also drift fisherman. Before you shell out extra money for a top-of-the-line finder, however, ask yourself if it will help you catch the exact species you seek

What are the features of shallow water fish finders?

Here are some of the features you’ll need to consider.


Transducers operate at varied frequencies, from 50 to around 200 kHz, although some go has high as 400kHz. You want one on the high end, fishfinders with 192 or 200 kHz, because you get more detail with higher frequencies.


Shallow fishing requires less power, which thankfully decreases price. Remember, though, that the more power you can muster, the better resolution you’ll enjoy. Just to confuse you even more, fish finding devices manufacturers may use one of two power measures, or maybe even both. They are RMS and Peak to Peak. It turns out that Peak to Peak equal RMS times 8. That means if a transducer’s RMS is 50 Watts, its Peak to Peak is 400. Low power transducers operate at 50 to 150 Watts RMS and high power use 250 to 500 Watts.

Cone Angle

The object projecting off the transducer looks like an upside down ice cream cone, hence its name. Cone angles range from 9 degrees to 60, but most go from 16 to 20. A wide opening containing a large number of degrees means the cone ends in a big circle. It’s best for shallow water because wide openings cover a lot of areas, but with lower resolution. When you become more advanced, and your wallet gets much deeper, you can graduate to fishfinders with dual beams transducers, triple beams and side beams. Just imagine the toys you’ll purchase after you win the lottery.
