Ice fishing flashers will tell you what depth objects (and fish) are moving at, allowing you to set your lure at the exact right depth to bring in fish. If you'll be moving between holes throughout your day of ice fishing, you'll want a traditional stand-alone ice fishing flasher. If you'll be hiking in to your ice fishing spot, be sure to check the portability, size, and weight of the flasher. If you don't have a separate fish finder already, you'll want an ice flasher that also works as a GPS and fish finder in order to give you the most information possible. At Sportsman's Warehouse, you can find ice fishing flashers from trusted manufacturers including Marcum, Vexilar, and Humminbird.
