So I got this wild hair that I think I’m going to buy a open water helix 7, get an ice ducer and mount it to my genz box. My question is what is a good price for an open water one? Found the open water equivalent to the ice unit (I believe) on amazon for $394. Humminbird says the MSRP on their site is $449. Considering we are getting to the end of the season, is it realistic to find one for cheaper?
