I have a feeling that you have not yet got the perfect fish finder. Marcum LX-7 Ice Fishing Sonar System/Fishfinder – LX-7 has features and technologies that make it an incredible ice fishing fish finder.

I have been trying to search the market for an ice fish finder that would beat the Marcum LX-7 Ice Fishing Sonar System. In its category, it has all been in vain. That is the reason that I cannot hold back from letting the world know how awesome this ice fish finder is. It is better than its competitors. It will make you throw away your mechanical flasher. It is an ice fish finder at a whole new level of innovation.

LCD Display

Marcum LX-7 fish finder has a much bigger screen than most of the other ice fish finders. A large screen is no good enough.  It is the details that the LCD screen allows, having 800 x 600 pixels gives an excellent resolution.

The display is real time. The display allows for easy to read and selectable display of the lures and fish and also the sea structures. The screen offers multiple underwater windows with inclusive vertical zoom, widescreen graph, and circular flasher. Marcum LX-7 has a total of 5 windows on display. I am always in a position to use up to three of the windows at a go.

Sonar Technology

Sonar technology is for the quick generation of images under the water. In a fraction of a second, the sonar targets the image and transmits it back to the transducer for display on the LCD screen. The sonar is powerful that enable it to penetrate to deep depths.

The sonar technology enables for monitoring the lure and excellent targeting of the fish. Target spacing is important in avoiding target clutter. The sonar footprints give for space different sonar signals thus avoiding interference.


On the dashboard, you get awesome flexibility.  There is a range of settings, and these settings allow you to choose any of the combinations that you want to use. You can choose to display the following; digital depth, battery voltage, interference rejection, or the targets adjust.

Color palette settings allow for choosing the color scheme that you prefer among the four selectable color schemes. The settings also allow for either automatic or manual range setting. I get the flexibility to choose the zoom window that I want from the four available. Also, you can choose to zoom in increments of 1″ while on the current window.

Updatable Software

We here case where time catches up with a particular technology. To avoid being outdated the manufacturer incorporates USB ports that will allow you to upgrade the fish finders software whenever you find appropriate.

Due to the upgradability, I term the Marcum LX-7 Ice Fishing Sonar System/Fishfinder – LX-7 as one of the most advanced fish finders. The horizontal graphs are better than those of its competitors. The graphs allow for a history display. That is the benefit of having both the flasher and the graphs on one unit.


The manufacturer incorporates a high-end transducer. The transducer allows for a three-dimensional view of the bottom. It gives you three cone angles to choose, 8 degrees, or 20-degree cone angles. The cone angle determines the transducers area coverage.

These cone angles make the transducer the ideal one for ice fishing. The transducer makes the sonar technology such a success. If you are still using the mechanical flashers, then your accuracy will turn around to 200% from 20 %. Now you can tell a fish without having to guesswork.
