Daiwa Lock N' Load Pole Bush This innovative pole bush from Daiwa is designed to increase catch rates and shorten fish playing times by up to 70%. The lock'n'load bush is designed to use a flush fitting elastic. please follow the guide shown below. This will ensure that the maximum level of locking control is obtained. Locking the elastic whilst playing a fish in the latter stages of the fight is acheived by lifting the pole end to create an angle which effectively locks the elastic in place. Should you need to give line to the fish, simply lower the pole tip, and the elastic is released.
