How did you come up with your copper at 30 feet down? Were you running them off boards?How many feet are your copper setups? We run meat rigs on our copper but you can use flasher/flies. A fishhawk to me is more important than a fish finder, definitely money well spent. Also you may want to consider going on a charter to shorten your learning curve. Or you can see if anyone is willing to take you out for the day and show you a few things. I'd offer but I'm out of state and when I do make it up I already have a crew with me.
