If this is your first fishing sonar device, you may struggle with hundreds of different models,brands and configurations.

Knowing the display standard and the sonar types are enough to make you confused.

Here LUCKY will guides you to know the fishing sonar and simplify the selection process so you can confidently make the right decision.

The following are some of the main factors you might consider and pay attention to when choosing a fish finder.

You can choose a super cost-effective fishing sonar based on your own needs. Trust me, it will enrich your fishing experience.

TRANSDUCER

Think of your fishing sonar as a small sonar device. A transducer is an essential part to every single fish finder which sends sound waves into the water.

When the sound waves hit an object (fish) in the water, the sound waves are reflected back to the fish finder. Then the sonar transducer receive and convert the echo signal.

A good fishing sonar depends on an efficient transducer to send and receive signals. LUCKY has two kinds of transducers: wireless and cable, which are easiest for operation and installation.

Most importantly,Whether you choose a wireless transducer or a cable transducer fish finder,It will satisfy you with all four fishing types(Shore fishing,Kayak fishing,Boat fishing, Ice fishing).

Beams and Cone Angles

Sonar transducers emit sound waves into the water that are cone angle rather than lines.

The cone angle tells you the width of the beam emitted into the water from your transducer.

A wider cone angle means that a larger area will get covered and detected.

However, the larger the cone Angle is not always better,because different scanning beams will be more or less effective in different fishing situations.

Wide beam scanning is good for large areas to get full information of depth and bottom structure, but with lower accuracy and detail.

Wide-beam scanning is best suited for shallower waters. Narrow-beam scanning provides a more accurate image but covers a smaller area.

It can find the exact location of the fish and also more suitable for deeper waters because the cones are not as wide.

Screen Type

The color screen of the fishing sonar makes the information coverted from the transducer easier to read and understand.

Black and white monitors are harder to read in direct sunlight.

In dark or cloudy weather, the black and white screen again appeared inadequate, with limited readability.

LUCKY's color display is not only use different color to recognize different information but also very high-definition, what's more with an affordable price.

Transducer Frequencies

One of the biggest factors in transducers is frequency.

Transducers usually have frequencies of 200, 192, 83 or 50 KHZ.The cone angles are directly related to them.

For shallow water, you'd better choose high frequencies, such as 192 and 200 KHZ.

For professional and commercial applications in deep water, 50 KHZ transducers work best.

The important thing to remember is that high frequencies show more detail on the monitor.

The higher the frequency, the more sonar waves the sensors emit and receive.

Finding the proper depth sounder or fishfinder to meet your needs requires a choice between numerous brands and models. Just buy what you need!
