Saw this on the google play site. Its called Dipsy Troller v3.0 and its just an app that lets you see the dive curve for most of the Luhr Jensen trolling products, I think.
So, does anyone use this and if so can you tell me how it works for you? The thing about apps like this and the other big one (Precision) is that you have to trust that their "data" that they base these things off of is accurate and not just "guesstimated". My feeling is that this stuff is a little easier to use on a rocking boat than flipping through a book and is really just intended to help you get a close starting point.
Anyway, thoughts, opinions or actual experience is much appreciated.
