I'm looking for a alternative to the livescope. I think they are awesome just a little out of my price range. The majority of my crappie fishing is done off a dock so I'm vertical jigging bush piles. My budget is around 600 I have been looking at the Aqua Vu HD7i but my home lake is typically murky so I'm wondering if something like that would be a waste of money. Thanks for your help I'm new to crappie fishing so any help you can give me would be appreciated. Thanks!
