Complete Guide to Buying a Fish Finder

Fish Finders Buying Guide

Fish Finders Buying Guide

There is no doubt that fishing has changed dramatically over the past few years and much of this has to do with the development of fish finding technology. With the right tool, you’ll be able to check the depth of a specific location, locate fish, check the temperature, and even examine the speed of the water flow. Some are even equipped with GPS technology, which makes it possible to add waypoints and create your own fishing haven.

As these products have gotten more efficient and helpful, they’ve gotten a little more difficult to buy. Below, you’ll be able to find exactly what to look for, when purchasing one of these products.

How They Work

In order to get a better understanding of these products and how they work, it is vital to understand marine sonar. Each of these products works with two individual components. The unit is responsible for displaying the results of a scan, while the transducer is responsible for making the scan. Suffice to say, the transducer sends out a sound wave, which travels directly to the bottom, until it reaches the surface. Once it reaches the bottom, the sound travels back to the transducer, which directs the information to the unit.

After the information has been received, the unit goes to work interpreting it, before displaying it on the screen. Depending on your locator, the screen will display a variety of different information. Each will show fish under your boat, as well as vegetation.

Power or Wattage

When you begin looking for a sonar unit, you will quickly notice that each has a wattage rating. This figure basically allows you to determine the overall power of the transmitter. Although more power is always better, it will also increase the price. Higher wattage is capable of ensuring better and quicker performance. Units with less power will take longer to provide you with an accurate readout.

In order to make sure that you’ll be able to benefit from your unit, it is vital to choose one that has at least 800 watts of power. For even better performance, serious anglers should opt for 3000 or more Watts of power! Remember that higher watts will allow you to fish, within much deeper waters.

Screen Pixels

To make sure that you’ll be able to read the screen clearly, it is vital to select a screen, which has a good number of pixels. Purchasing a unit, which has very low pixels, will result in a choppy display that is difficult to discern. Although you should determine how much you’re willing to spend, it is vital to choose a unit, which displays at least 240×240 pixels on the screen.

Of course, a bigger budget will allow you to choose a much better display. You should also determine, whether or not you’ll be satisfied with a black and white screen. You’ll need to make some personal decisions in this regard.

Frequency Capabilities

The frequency is very important and should be one of your main focal points, when searching for a high-quality fish finder. It is vital that you know the basics of the term, before you go out there and purchase any brand.

Transducers are equipped with a single, dual, or multiple frequencies. To break these down for you, the single frequency is only capable of pointing a single beam directly down below the boat. These transducers are suitable for lakes and rivers that have less than a 200” depth and available in frequencies ranging from 192-200 kHz.

The dual frequency is exactly that, because it has dual (two) frequencies, which are normally a 50 kHz and 200 kHz. The 50 kHz is capable of scanning around the sides of the boat, because it has a wider cone angle, while the 200 kHz will again only show the areas below the boat. The 50 kHz is more powerful and will penetrate depths greater than 200”.

Additional Options

It is vital to make sure that your fish finding unit is going to be able to enhance your game. With this in mind, you should consider, whether or not you need temperature, speed and distance readouts. Truthfully, this will come down to your particular style of fishing. If you’re totally into trolling, you will be able to enhance your creel count with speed and distance information. For drift fishing, speed is essential. Remember that some species of fish are very peculiar and will only take bait, if it is traveling at a specific speed!

Temperature is actually beneficial regardless. By knowing the temperature, you will have a much easier time locating the specific type of fish that you want to catch! Although this will come down to your personal preferences, it is a good idea to get a unit that is capable of providing you with temperature information.

Portable or Fixed?

Each buyer will have the option of choosing between a portable fish finder or fixed unit. Obviously, the portable unit offers the convenience of being very transportable, while the fixed models are a little more difficult to move. Again, this decision will be based on your particular situation. Those that own their very own boat should definitely opt for the fixed unit, since they’ll make life tremendously easier. On the other hand, if you’re renting a boat, you’ll want the portable model.

At the same time, ice fishers and anyone, who has access to a fly-in retreat, will want to stick with a portable unit. It will give them the advantage of moving the unit easily, once they’re ready to go home!


If you’re looking to splurge and want even more convenience, you should consider purchasing a unit with GPS capabilities. These units are capable of pinpointing your exact location regardless of where you are on the water. You can also use the GPS technology to create waypoints, which will make it easier to get back to shore. GPS can certainly increase the price of the product, but it also offers many awesome features.


When searching for a replacement for your old finder, it is vital that you take the time to do a bit of research on the new products that are available on today’s market. Keep in mind, while you are shopping for the best fish finder, what your specific needs entail. If you are a deep-water fisherman, then you will definitely want to purchase a dual frequency transducer, but if you are not, a single frequency will suffice your needs. A fish finder will definitely make your fishing experience a whole lot more enjoyable. For additional tips on how to set up your fish finder, check out our guide here!
