When long range casting with big leads or spods its safer and more efficient to use 45lb ESP shock braid as a leader. the optimum length of the casting drop plus the distance from the tip ring to reel plus three or four turns on the reel spool. Like the 20lb ESP spod and marker Braid this matching shock leader is non stretch so all the casting power is transmitted directly to the lead for a maximum distance and accuracy. when feature finding all the signals are equally well transmitted and not diffused as they would be through a stretchy mono leader.
