Scheel has a 7’ Walleye Series rod that works perfectly for this application. It will handle a 3 oz. bouncer. When I’m fishing I usually hold the rod, but my guide clients typically put them in the rod holders. Scheels also has similar rods in their less expensive series that work well too.
If I was exclusively putting them in a rod holder, something a little longer would work. I’ve tried to hold onto a 7’6” or 8’ all day and I found it uncomfortable.
