I bought my Showdown a couple of years ago. It works fantastic, and I have never had any issues with mine. For a low tech redneck, even I can work this one. Makes more sense to me since you are fishing vertical, you might as well watch what is happening vertically. That being said, I have no experience with any other type of flashers. All I know is I won't fish without mine. Just having the luxury to bounce from one hole to the other and instantly see the deph, sure helps me. I paid over $300 for my dual. For the extra few bucks, buy the dual. More easier to zone in closer if there is lots of structure below. Good luck!
