I always check my equipment (bait) to ensure I understand it limits before sending it down for the first time.
Example: I set my speed over ground (SOG) to 1.5 MPH to start and then view the equipment’s action off the side of the boat. I then increase the boat (SOG) in 0.5 MPH increments until it fails to perform.
Be sure that your knot to swivel is straight or your results will be inaccurate.
These findings has helped me to sort out which manufacture spoons and size work best with each other, along with the minimum and maximum down (ball) speed I can run. Given there are to many variables for each of our own setups choices, line type, size, leader, swivel, ext… you get the idea.
Additionally I found this information some time ago that I found help full as I was putting my program together. I refer back to it at times when things get slow or I question what I could do to improve.
