Take your fletching precision even further.
The Bitz Pro Setter™ 1.5° and 2.5° Angle Expansion Kits are designed to give archers more control over vane steering, broadhead stabilization, and long-range forgiveness. These precision-machined inserts integrate seamlessly with your existing Bitz Pro Setter Angle Setting Kit and Bitzenburger jig.
Whether you’re micro-tuning a high-FOC hunting arrow or dialing in a long-range 3D setup, these lower-angle options allow for subtle steering adjustments without over-inducing drag.
Why add 1.5° or 2.5°?
-
Fine-tune broadhead control
-
Optimize arrow rotation rate
-
Reduce drag while maintaining stabilization
-
Dial in the perfect balance between forgiveness and speed
The 1.5° option is ideal for shooters wanting minimal helical with efficient downrange flight.
The 2.5° option offers a slightly more aggressive correction while still keeping drag lower than traditional 3°+ setups.
Each kit is engineered for repeatable, consistent vane angles — no guessing, no eyeballing, no trial and error.
If you’re serious about arrow flight and want complete angle control, this is the next step in precision fletching.
