GPS speed vs speed at the ball
When I’m meandering without a target depth or way point I like to troll directly into the current. It seems to me doing so will have both sides of my spread working at the same speed. I attempt to do this by watching the angle of my center rigger cable and rigger rod. I try to get them parallel and directly behind the boat. I will also watch to see how well my Off Shore boards are lining up. In addition the pull and angle on my Dipsy rods will be similar when going into the current.
In past years when fishing was better you would see the MKE charters pick an angle into the current, typically NNE to NE. They would hold that angle as they changed depths and often not turn on fish figuring they had the right angle and more fish would be coming. That works well in open water but when fishing the structure on the Racine hills, they affect current more and not as effective until beyond the 3rd hill.
Regardless of whether fish are in a river or open body of water they are going to face into the current because it brings food to them. I have always done best trolling across the current and is one of two reasons I try to troll in a serpentine fashion as much as possible. Serpentine trolling patterns also allow baits to change levels and speed in water column.
in my experience fish generally feed with the current on open bodies of water. walleye and salmon in my experience.
river fishing is different and then I would agree with you.
plus going into the current on lake michigan requires you to go much faster, closer to 3 or higher, than I like to run. just puts to much pressure on the all the gear. drags need to be tighter, which I don't like.
anyone else have any thoughts?
I agree with your train of thought. If no change in rpms to keep Depth Raider at 2 mph regardless of direction one would assume no current.So if no current nothing for fish to align with. And lure action should be the same regardless of direction.
