How To Use Fish Finder (The Right Way)

How to Fish: Using Your Fishfinder

What Should Look?

When identifying excellent fish finder the main question that should be running in your mind is whether what you settle for will help you catch more fish or not.

It is obviously easy to get confused when you are confronted with all the brands available in the market, with positive information about each of the varieties you may find in the market of the fish finder.

That is why there is a list below of some of the important aspects you need to consider when choosing one.

Picking Out a Fishfinder

The Display Screen

From the varieties of fish finders, you will come across; you need to know that there are those with a black and white screen and others have a colored screen.

I suggest that you need to opt for one with a colored screen because it will help you see images better compared to a black and white screen.

Additionally, nowadays, fish finders with a colored screen are fairly priced, and so, the cost to incur should not be one of the reasons why you should opt for a black and white screen.

Secondly, you need to consider the size of the screen of the fish finder you opt for because the larger the screen, the easier it is to locate where the fish are.

However, the biggest challenge, in this case, is that if you need a fish finder that is portable, then, it is not possible to carry one around if it has a large screen.

Hence, you need to consider which among the two is a priority and forfeit one in place of the other attribute. That means that if you opt for a large screen, you may not be in a position to carry it around but it will be easier to locate the location of fish under water.

On the other hand, if you opt for a fish finder with a screen that is 5 to 7 inches wide, which is the recommended size, you will still be able to locate the fish.

Otherwise, if you opt for a smaller screen for portability reasons, you are able to move with this gadget from one point to another but locating fish under water with ease, might be your biggest challenge.

Depending on your style and preferences, the main thing, in this case, is to go for a screen that will serve the purpose intended in the best way possible.

Hence, the choice of an appropriate screen size may differ from one individual to another, but you are good to go with the recommended size as highlighted earlier.


This is the main component that helps you locate fish under water and more than that; it also captures whatever is underneath the surface of the water as well.

The transducer sends sonar signals under water, which in turn bounce back from any object underneath. Once, this happens, the signal is received by the transducer once again, and it is converted to an image for you to gain a clear picture of whatever is below the surface of the water.

Because of the fact that a particular cone angle can work better in some situations compared to others, dual beam transducers are now available, which combine both the bigger degree and wide cone technologies in one unit.

There are other varieties with multiple beams as well, and these have four or more beam in addition to the ability to relay 3D images. The side beam transducer is another variety that helps shoot signals on the side to give you the opportunity to cover a wider search area.


Every fish finder has a power rating on it and it is indicated in the form of watts. If you choose one with higher wattage, you will enjoy better speed when the gadget is displaying readings, better effectiveness and more depth of usage.

These are some of the attributes that serious anglers will be seeking when trying to identify fish finder, and obviously, they help them realize better results in the whole process.

If you intend to use a fish finder on shallow waters, I suggest you use a 600 watts gadget because, in such an environment, it will be up to the task and will deliver accordingly.

Also for those who go out on such expeditions for fun or if you are not one of the serious anglers, a fish finder with this kind of power will work best for you as well.

Deep water fishing is a whole different environment altogether in all aspects you may imagine even though there may be some similarities with shallow water fishing.

In most cases, experienced anglers and the skilled go out to locate fish in such environments and for these, a fish finder with higher wattage will be most appropriate.

Hence, it is worthwhile to consider the depth of the waters you will specifically need to use the fish finder on because this will help you pick on the gadget that suits that particular environment best.

This consideration should be made prior to the purchase of the fish finder to ensure that you do not incur the same cost in the near future when you finally realize you need one that has a higher power rating.


This is another feature that every transducer should possess, and it is quite critical in this particular gadget. Identifying a fish finder that is appropriate for you will depend on the ability to choose one with the right frequency, and you need to consider this factor.

The frequency is an important consideration because it is directly related to the cone angle.

The implication, in this case, is that a higher frequency will relay more details on the screen which is obviously something that you will appreciate and you will be out to achieve as well.

The majority of the transducers available in the market today have frequencies ranging from 50, 83, 192 and 200 kHz.

Therefore, for those who wish to reap the benefits that dual frequency transducers have, this will be a viable option that they can capitalize on.

Again depending on the environment you need to use the fish finder and your preferences on the same aspect, you should have an easy time finding the best with this insight.

Other Considerations

Portable or fixed options

As your source for an appropriate fish finder, you will have two options to choose from and these include the portable one and the fixed variety. As the name suggests, the portable variety can be moved from one location or another depending on the need on the ground. This may be the best option for you because of various reasons.

The other reason why a portable fish finder may be the best option for you is if you engage in “fly-in” fishing and ice fishing because of the nature of each of these tasks. A portable one will have its own carrying case in addition to a power supply that serves the gadget.

Also included in the package is a transform mount for installation purposes and a transducer that is connected to the transform with the help of a suction cup.

If you own a boat and you use that particular boat for all your fishing ventures, then a fixed fish finder will be the best option for you. That is because you may not give it out to anyone else for them to use it.

That way, you have the freedom to fix the device at a specific location on your boat and this can either be on the trolling engine, stern or hull.

Final verdict

From the list of various fish finder tools reviewed above, it is evident that each of these gadgets has unique features that will not only give you a wonderful experience while you are out on some fishing expedition but more than that, you will be able to enjoy the latest technology in fish finding.

By embracing either of the options outlined herein, you are subscribing to a revolution from the way fishing has been done in the past, to a wonderful experience in such ventures that will make every fishing expedition another great story.

Make the wise decision today and opt for the right fish finder from the list above and see how angling will be something you always look forward to, and not just another moment to pass the time.

It is a whole new way of making angling the best adventure you can ever imagine. It is a whole new way of making angling the best adventure you can ever imagine.
