Ok, guys I've done quite a bit of trolling, mostly surface or slightly subsurface in the Gulf of Mexico. Am interested in getting some baits down to the big fish on my finder 60-150 ft if possible. Problem is I want to continue trolling the surface at the same time at 4-7 Knots. Have bought two Scotty electric downriggers with 10lb weights and tried them last weekend. They sure don't stay down too deep when trolling at these speeds, I bet 60 foot of cable blows back and is only 20 foot deep at 5knts. What are my options, whats the most efficient way to accomplish this? Any and all replies appreciated.
