The first bobbin on the market that allows you to choose the length of the tube. Choose between the trout (short head) or the predator (large head) to give you a custom fit for the size of your hand or fly. The steel carbide tubes draw the heat away from your thread so you won't damage the thread. To swap heads unscrew the head on the bobbin and remove it. Take the other tube and head and slide them onto the bobbin, select the tube length, and tighten. It could not be easier! We put the choice in your hands"|
