Ice fishing flashers use a rotating-style display that monitors fish activity near your hole via sonar, allowing you to adjust line positioning. The earliest spinning-wheel flashers were used by anglers all the way back to the 1960s, but technology has come a long way.
Today’s ice fishing sonars come in several different styles, from water-proof handheld devices to digital locators to LCD fish finders and more.
Here are the main considerations when deciding between a ice fishing flasher vs. sonar:
Yes, sonars work by releasing an acoustic signal through water, where it bounces off an object and returns that signal back to a device -- particularly useful when fishing. In fact, a transducer can be placed on top of the ice to send and receive signals, since sonar waves travel more easily through ice than water.
In short, ice fishing sonar is more reliable because, although more difficult to read, they provide reliable signals in any condition. In contrast, underwater cameras are less effective in murky water or at night.
