I'm planning to fish a lot of deeper water this august, especially in search of Kokanee and Walleye that were supposedly stocked in my home lake. I've always wanted to put a fish finder on my canoe, but never really understood what I needed/never had the money.
Ideally I'm looking for some that:
-Can create and save bathymetry (contour) maps of my lake.
-Works accurately in up to 70 feet of water.
-Can be mounted to a canoe.
-Is as cheap as possible.
I know those new ones that you use your phone as the screen for are fairly cheap. Are they the cheapest option? Are there any great value picks out there I should be aware of?
-Thanks a lot
