RaidZap Xact Adjustable Fly Tying Bobbin
The RaidZap Xact Adjustable Fly Tying Bobbin is 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 easily swap heads simply 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.

This bobbin makes a big difference in my fly tying process. The ability to switch between head sizes fits my hand perfectly. The steel carbide tubes keep the thread from getting hot, which helps maintain consistency in my knots.

I’ve used several bobbins before, and this one stands out. The adjustable head is a game changer. I can now tie smaller trout flies with the short head and larger flies with the predator head without any strain.

The design is simple and effective. Swapping heads takes less than a minute. The thread stays clean and doesn’t get damaged, which I’ve noticed in previous bobbins.
