A handheld GPS is the cheapest way to go to determine speed. Some Depth Finders have GPS that tell speed. There are other Depth Finders that you can add speed sensors too, but I've heard they are not very accurate.
Troll your jigs over shallow spots or points to determine the depth you are running (The rod tip will bounce when your hitting bottom)
Also if your trolling curly tails, you can drop one down in the water beside your boat and speed up until it starts turning, so atleast you know your going fast enough to get action from you bait.
