Criteria Used For Evaluation


Ease of Use

Everyone wants a device they can easily use and operate. A straightforward tool makes fishing fun and enjoyable. And the ability to perform whatever action you feel when on the lake or sea. Several ice fishing flashers are on sale, but while making your choice, go through the specs and ensure it has an easy to use review. Or you might be hitting a rock with that one you want to buy.

The size of a sonar matters very significantly to allow easy usage, and you must go for the ones with a smaller scale. As the more significant the size, the more difficult it is to transport and could be an inconvenience with all that size. Some products might require a big scale for a compelling performance. But coming to sonars, big size is of little importance.


A sonar that can withstand wear, damage, or pressure for a long time is indeed good, and that should be the one you should be adding to your cart. It is obvious that all device will fail at a time, but a tool that can get you as much fish as possible, before going to its grave, should be the one you should be considering, as it not only gets you abundant fish, it saves you a whole lot of money too.


The ability to move around with your sonar could be what you have always wanted, as you have no idea when you might come across a good lake. A portable sonar ensures more accessible transportation too; invest in portable sonars if you can, as the benefits supersede that of larger sonars. A massively heavy sonar might not be too good for your fishing experience. A heavy object incurs more weight to you, as it might not be the only thing you want to bring on-board. Sonars nowadays are designed to be portable, adjustable, and light. Choosing amongst the lighter ones could be a great choice.


A product with a good and notable brand can grant you satisfaction, comfort, and happiness. When you purchase a product that people have used consistently and experience a positive result, the consumers will form an opinion on the brand being trustworthy. Which makes more buyers want to opt. The brand also saves you the decision-making time, as there are lots of products to search on Amazon, for example. But when you type the exact brand you want on the search bar; it makes it easier to find what you were searching for. The brand also helps in creating a difference as it quickly notifies what makes a product and desirable that others compared alongside.

The brand name provides safety. Also, it assures you the certainty of acquiring a product you can trust to avoid disappointment. The brand also adds value. Most times, consumers are willing to pay higher for branded products compared to unbranded products. Is the quality better, the feeling or look, or does the society recognize the brand? Technically it’s a combination of the three questions asked because products, which are branded successfully, make more through the premium prices they command.

The brand also gives consumers a good reason to share. By sharing our experiences with others, so they can learn how useful it was to us.


The accuracy of the fish finders is essential, as the skill can tell you when a fish is right beneath you and when it is right to throw your pole. A less accurate sonar might only detect an obstacle, and you wouldn’t want to bank on such a false alarm.


Expert Tips


A Sonar Capable of Working in Any Environment

It will also be a great idea to purchase a sonar that could work in any environment or water condition. Several sonars lack this feature, as it limits your fishing to favorable environments only. But a sonar with the ability to work in all environments allows you to fish anywhere, anytime and any day.

Sonars with Sound Zooming System

Purchasing a sonar with a zooming system is a good tip; because it enables you to zoom objects beneath the water to be absolute on what your signal is packing. Could be a rock, debris, or an obstacle. But a sonar with a zooming function shows you what your sign is picking.

Easy Fishing At Night

Acquiring a fish finder with an LED backlight is indeed an important tip. Some fishermen reported catching more fish at night than during the day. So, if you would love to fish at night, you’ll need a fish finder with an LED backlight that you can easily read at night. Most monitors could only work in daylight.

 Other Factors to Consider


Battery Life

The battery life for a fish finder is essential. Because having a sonar with a weak battery affects not only your fishing time, but also it makes you get tired of the product. Creating more expense and waste of materials too. Majority of fish finders consume around 1 amp of current when it

is powered from 12v source. But smaller models take less than that, while bigger ones, especially the ones having GPS combo takes more power than that.

The first thing is to determine the battery required capacity, by multiplying the finder current in amperes by the operating time desired that is in hours, which is given in ampere-hours (Ah).

Weather Resistance

Several sonars don’t perform well in diverse weather conditions due to their low specifications. But a sonar with resistance to weather condition should be one of your priorities because the weather might change anytime, could be favorable or it could be not. But a good sonar with a better weather condition will work absolutely without having complications. But a sonar without such feature might be affected by a sudden change in the weather, irrespective of when you bought it.

Invest in sonars with excellent water resistance, and you’re perfect to go.

Water Resistance

Water-resistance is also an excellent feature to look out for when making your choice of sonars. Because you’re dealing with water and it would be a great deal if your sonar is water-resistant.

With many sonars in production today already water-resistant, in a few years, there will be limited sonars that are not water-resistant. Therefore, I would go for a sonar that is water-resistant.


Before you decide to buy any unit, you should consider the power of the fish finders you’re looking. This function occurs because a fish finder, through its transducer, converts sonar waves. The readings are less reliable, and the waves slower when there’s less power. But in the availability of more power, the waves are faster, and the readout is more accurate. When you want to fish in shallow water, much power won’t be needed. But when your choice of fishing is in a deep lake or saltwater, you will need a fish finder with as much power within your affordability.


  • Your fish finders will display a depth reading of almost 400 feet, for every power of 100 watts at 50KHz.
  • Your fish finders will reveal a depth of nearly 100 feet, for every power of 100 watts at 200KHz


Frequently Asked Questions


Q. How do I tell what’s on the screen?

A. These balls down to fate mostly, but you’ll get an echo when anything denser than water pops. Even though you do not see the fish, there’s no assurance that it isn’t there. This process is where your skill comes into play because there are great places you can find fish like brushes, trees, rocks, and weeds. All you need to do is develop your skills to identify them, and then you can make your big catch.

Q. What’s flashers or LCD?

A. Even though it is simpler to read an LCD than scrolling across the screen, they are the same. The vertical columns of pixels explain it better. That is also the exact thing you’ll be getting in a fishing flasher. Without the LCD undergoing some averaging, filtering or taking a few surroundings before you happen to see it. Just know it’s about time, the exact time, it could be gone by the time you get to view it.

Q. What is the right frequency I should use for shallow, deep water, and mid fishing?

A. Generally, you would want to use the lowest power but the highest frequency that will still deliver the information without infusing the return with excessive noise. One well-known rule is this, as you fish deeper, the rate becomes lower. Sound waves can travel well in water, and better returns are provided in deep water by lower frequencies, which goes farther.

Q. Is there a possibility of determining what species of fish are down there by looking at the screens returns?

A. The characteristics of their sonar returns make it possible to identify fish species, but this is a skill that requires practice before perfection. Most sonars can detect most fish due to their internal bladder with the giant air bubble acting as a sound reflector. The shape, size of the bladder varies by species. Through practice, these subtle characteristics could be more precise.
