How handheld fish finders work?

Most fish finder tools use sonar technology and nothing different in handheld fish finders as well. These devices spread sound waves inside the water, and when the sound waves hit an object, the device will let the user know about it. The signals received from the waves will exactly tell about the object that has encountered in the water.

Factors to consider for the Best handheld fish finder

As we mentioned, the selection process can be a bit intimidating for the rookies in particular since the outlook of portable fish finders is more or less identical. So read the below section of the article vigilantly to own the best possible product.


Even though there are more important parts inside a handheld fish finder, the most crucial thing for the user is the display. This where you monitor all the important data; some gadgets have built-in displays, and others let you examine the information via your mobile phone.

The big-sized screen will help you read data easily in order to react to the situation quickly. If you can, go for a device with a color display because it is pretty helpful to read the data when they are displayed in separate colors. But, finding a portable handheld fish finder under $100 won’t be that much easy with the color display feature; if you are on a budget we have few products in this article that are tailor-made for you.

However, if you find a device that has the capability of syncing with smartphones, in that case, you obviously get the opportunity to work with much comprehensive screen. In addition, you can work with an even bigger screen when connected to the portable fish finder to a tablet.

Sonar technology

Fishing Sonar

This is the main factor that decides the efficiency of the device, and this is where most people go wrong with their purchase. When it comes to sonar technology, you should pay attention to two main aspects; they are frequency and beam angles. Different devices use different frequencies. So, if you can grab a handheld fish finder with multiple frequency capacity, the more details, you will receive when it is in operation.

However, the low-budget products usually come with single or dual frequencies, and if you want more functions and accuracy from portable fish finders, you must be ready to invest some money.

Moreover, the level of frequency depends on the depth of the water you are going to explore. This means if you intend to use the fish finder in deep water, you should eye low frequency and vice versa.

Depth of the scanning

This says how deep the device can scan. The range of scans varies from one fish finder to another. Some of the top-rated units have the competence to scan up to 5000 feet. However, an ordinary portable fish finder works 500 feet region.

Power source

The priority of a fish finder has to be given to mobility; so, it will be ideal if you prefer a handheld fish finder with rechargeable batteries. Also, these batteries have the ability to last about 5 hours with one recharge.


There are some devices with AAA batteries, and they too become in handy for long fishing duties because all you have to do is carry spare batteries, and there is no recharging hassle associated.

Water resistance

Water and electronic devices usually don’t go hand in hand. But, the fishing gear you choose must-have qualities in them to bear a splash as you always interact with the water. You don’t buy handheld fish finders every day of the week, so it’s your duty to check all the aspects as much as possible.

Handling ease

It should be easy to use, and if the device demands any mounting process, it should be comprehensive and simple. Overall, if you have to pay more attention to the functionalities of the device, it would take your mind away from the fishing process, and you will lose efficiency.


One thing you have to remember is that a high-quality handheld fish finder doesn’t come cheap. So, a cushion of a warranty would always be advantageous, and it brings a sort of confidence over the purchase. That said, manufacturers know that you are going to use these devices in harsh conditions; hence, they do not provide massive warranty periods. But, as they say, something is better than nothing.


There are cheap products as well as expensive ones. But, we urge you never to underestimate the value of a cheap product or overestimate the pricey fish finders. First, understand your requirement precisely and then look for the features and finally compare the price.
