Ice Fishing Sonar Buyer’s Guide

ice mountains

There are a number of factors you should consider when buying an ice fishing sonar. Here’s a few of them now.

Display & Screen Resolution

Screen size and resolution are something you should think about. There could be a lot of glare while you’re out on the ice, or maybe you are fishing at night.

Either way, having a device that can display the relevant information clearly in all environments will definitely be beneficial.

Backlit screens make help display data more vividly, and of course, a larger screen will help too. The latter needs to be balanced with portability, however, as you will want a sonar that is easy to carry around. But more on that now…

Weight and Portability

Weight and portability are two important factors and are obviously connected. A lightweight unit that can be easily carried to your fishing spot, while also being easily placed in your fishing holdall, should be the preferred choice.

Dimensions are also an issue here, as while you want durability with the aforementioned adequate screen-size, a small unit will be easier to store once the fishing day is done.


An ice fishing sonar is going to get its fair share of knocks and bumps. It just comes with the territory with any outdoor pursuit.

To ensure your chosen device is up to the task it should be robust in design, (i.e, well made), using materials that can handle cold temperatures and contact with the hard ice.

Don’t be tempted to use a normal fish finder in below zero conditions. They are not designed for such tasks, and will not have the durability and resistance to the cold exposure, a true ice fishing sonar will have.

Connected to durability is the level of water resistance. Melting ice, rain, the waters you are fishing in, could all end up on the surface of the sonar. To have sufficient resilience against all of this is a must.

Besides, water can seep through and damage the electronic components of the fish finder.

Beam Angle

So far we have covered how the sonar is built in terms of size, portability, and strength. Now let’s look at the components and features that go into a high-quality device.

One of these variables is the beam angle. Inside the unit, you have a transducer that scans the water beneath the ice, using sonar to detect the presence of fish.

The sonar beam angle is how far your device will be able to scan the water. Narrow beams with greater depth will provide data in deeper waters, while a wider beam will provide a larger range, albeit over shallower depths.

Some devices will allow you to alter beam angles, while others will not. Check the specifications of the sonar you interested in, to ensure it has the capabilities you need.


The frequency will also impact the scan area and depth of an ice fishing sonar. High frequency will provide you with more information over shallower depths, while a lower frequency device will be able to scan deeper with fewer details.

As a practical example, a sonar working at a frequency of 200kHz will give you a lot of data points over shallow waters (especially combined with a wide beam).

However, if you find yourself regularly fishing deep waters, a lower frequency of between 50kHz and 100kHz, would be a better choice.

Again, many devices will allow you to select different frequencies, so bear this range in mind before you buy.

Battery Life

Battery life is very important if you are out for a long day’s fishing and do not want to worry about how long your sonar will operate.

High-quality devices with built-in Lithium-ion batteries are the best choice here. The charge life is much longer, and you should get more than enough power while you are out on the ice.

4-6hrs is the average amount of time you should expect, with top-end devices lasting up to 8 hours or more. Anything less than 4hrs is a sign of an inadequate system.


Having a budget in mind before you buy is always a good idea. This, along with your requirements are the best way to narrow down your buying choices. At the same time, you have to be realistic.

f you don’t have the budget, your wish list might need to be reduced. If you can’t budge on that, you may have to find more money to buy the device that best suits your needs.
