Flasher opinions, help and advise

[Top_of_the_chop]

Hello fishing community. I'm hoping to get some help and advise from those of you who are familiar with flashers. I've never owned one, but am looking to make the switch from a traditional fish finder. This will primarily be used for ice fishing. I'd appreciate any input, good or bad, on as many makes and model flashers you all have owned and used. Thanks in advance, I look forward to hearing the input.
