i set out about 10 feet so the dipsy starts to dig in and pull away from the boat . making sure the spin doctor and fly get pass the rigger .( my rods are 10 ft so it helps with the longer rod to pass the rigger) then i set the in the holder , as Sk8man said let out slow with the drag . the most important thing is the person at the helm keeps the lines straight behind the boat and don't make any turns while while deploying the dipsy
