Bobbin CerMag by Rite
If you are tying larger flies, or especially those that have longer shanks like streamers and saltwater flies, the CerMag offers you the additional length you need. And often times, these flies require heavier, tougher thread–which is why they have built this bobbin with a high-quality ceramic tube, to help you avoid cutting thread due to extreme wear and tear.
The durability and length of the CerMag will keep you cranking out those hefty patterns all year long.

I’ve been using the CerMag bobbin for streamer ties, and it’s made a big difference. The ceramic insert holds up well even with thick thread, and I no longer have to cut my thread mid-tying. The length is perfect for long shanks, and the tension is consistent.

After switching from a regular bobbin, I noticed less thread breakage. The ceramic insert is durable and the stainless steel feels solid. Works great with deer hair and heavy-duty patterns.

It’s a solid upgrade for saltwater fly tying. The extended length helps with long shanks, and the tension system is smooth. A bit heavier than standard bobbins, but worth it for frequent use.

Used it for a week-long fishing trip and didn’t have a single thread break. The click drag system gives precise control, and the ceramic insert stays intact even under pressure.
