Ok, Can't get parts(transducer) for my Humminbird matrix 10 fish finder, so I guess it is time to upgrade. I got a 20' wooldridge sport. I would LOVE to get a transducer that would work thru aluminum, so i don't have to keep buying transducers!!
What is everyone else using? I run alot on the rivers, but we do the seward silver derby every year, and might try the valdez derby. So I still need some range, but I would really want it to work on the rivers really well. esp when running on step (this might be an installation trick)
Thanks for the help/info
