Ice Fishing Electronics: Flashers, Graphs & Live Sonar

A lot of the electronics advice online is written by one brand's fans. I cover Garmin, Humminbird and Lowrance next to each other, plus Vexilar and MarCum flashers.

If you remember one thing from this section: the live sonar to buy is usually the one that plugs into the screen you already own. And if you don't own a screen yet, a flasher is still where I'd tell most people to start.

Still to write: display and live sonar compatibility charts, and lithium battery sizing for cold-weather runtime.
