The Marcum LX-7 is a remarkable piece of equipment. This product features a panoramic 8-inch LCD with four different user-selectable color palettes included. It has a “dashboard” that can display digital depth, battery voltage, range, gain, interference rejection (IR), target adjust, or any combination of these.

This ice-fishing sonar has great battery capacity and will provide you with several hours of use. We’ve found that turning down the backlight slightly also helps increase battery life. Its dual-beam transducer shoots at 8º and 20º cone angles, and sports multiple flasher settings.

What is the Best Ice Fishing Sonar in 2020?

Fishing is a relaxing sport, and a great way to enjoy your weekend, especially when you catch a ton of fish! However, it can be a big downer when you don’t reel in any fish after hours of sitting in a spot. It’s even more painful when you have to do it in snow. This is where having the best ice fishing sonar comes in handy.

What Are Ice Fishing Sonars?

Fish sonars, also called fish finders, are devices that can help to locate fish underwater. The device uses SONAR (Sound Navigation and Ranging) technology to find objects, such as fish, underwater. It emits sound waves that get reflected off the fish and then displays those findings on a graphical monitor. Modern fishing sonars also include other systems such as GPS navigation systems, electronic compasses, and marine radars.

What’s the Difference Between Normal Fishing Sonars And Ice Fishing Sonars?

Now that we’ve gotten the definition of fishing sonars out of the way, the next question is whether you can use the same type of fishing sonar for regular and ice fishing. For the most part, you can. However, you will need a fishing sonar with a detachable transducer and screen when ice fishing, or else you won’t be able to use a regular fishing sonar in an ice hole.

Ice fishing sonars are also called fishing flashers, and they generally have more accurate and advanced technology. They will typically give you the exact depth of the water, including the fish’s size and location.

Why Do You Need an Ice Fishing Sonar?

On an ice fishing expedition, I’d hate to have to guess where the fish are. Why not end the guess-work and ensure you have the right equipment for the job? The extra GPS, compasses, and marine radar systems that come with the sonars could also come in handy.

Here’s a bullet-point list for why you need an ice fishing sonar:

  • You get information as to water depth
  • Higher chances of reeling in fish
  • Easily identify fishing hotspots
  • Clear access to what’s happening underwater

Factors To Consider

Now that you’re convinced that getting a flasher is a smart, safe choice, you might be wondering what factors to consider before choosing one. We’ve compiled a list of criteria to check for when going ice fishing sonar shopping for your benefit. These are what you should pay attention to:

Portability And Weight:

When going ice fishing, safety should be your primary concern. You’ll want to get a flasher that you can move around quickly with and won’t make you lose balance on the ice.

Transducer Beam Angle:

The transducer is the part of the flasher that produces the sound waves. The beam angle refers to how wide the sound waves get when they get sent out. The wider the angle, the greater the area the flasher covers.

Display:

The display of the flasher is also important. Larger displays will make it easier to read, thereby helping locate the fish easier. Backlit displays also help enhance readability in whatever conditions you might find yourself in.

Power Source And Battery Capacity:

As a general rule, the higher the flasher’s wattage, the more powerful it’ll be. Battery capacity is an essential factor, and we recommend you go for an ice fishing sonar with a battery life that can last your entire ice fishing trip. Some devices come with a backup battery, so you might want to consider those.

Frequency:

The transducer beams’ frequency can determine the area, clarity, and depth the ice fishing sonar can get. Higher frequency beams are typically more accurate and can help you distinguish between a single fish or a school of fish.

Sum It Up! The Best Ice Fishing Sonar in 2020 is…

Although all of the products listed above offer premium quality, our personal favorite has to be the Raymarine Axiom.
