Tad Poles, Dipsy, Inline wts vs TT divers

[wakina]

I think walleye2go nailed it, along with the fact that the angle from rod tip to diver is becoming sharper and at an increased speed as the retrieval process adds more speed both of which adds more force to the face of the diver causing it to veer left or right to relieve that downward pressure. I have been using the TT divers since they first became available and have never had a problem with them in any way.

I also know that TT divers are a piece of equipment that I do not discard regularly so my experience with them is limited to the few that I have. The Old school Jet Divers were another thing though with several filling with water and some never pulling straight right out of their packaging but never with the TT divers. The hardest thing about using the TT divers would be getting the tripping device set right so they stay set with only the lure attached but trip with the hook up of even a small junk fish.

In summary, I think what you are witnessing is the combined mechanics of Trolling speed, Prop Wash, added speed from the retrieval process, the decreasing angle from rod tip to diver and the added forces those things apply to the divers face that are causing your concern.

I had to edit this because I did not answer your question directly with the original reply. That answer would be that yes, I do witness the zig and the zag behaviour as the divers get closer to the boat and that aspect of the diver does/has not concerned me. The zig-zaging is most pronounced with the diver tripped as the angles of force from water resistance can change with the diver in the free swim/tripped position. A diver that is not tripped will move one way or the other and kind of stay on that course and just keep bearing in that direction until it breaks the surface.
