Features:
1. Innovative bayonet design: The innovative use of the nock-shaped bayonet design can reduce the damage to the bowstring better than the traditional T-ruler
2. Dual material: The clip part is made of the same material as the nock, which has good toughness and does not hurt the string. The ruler body part is made of aluminum alloy, which is light and strong.
3. Two scale units: Both imperial and metric systems can meet the needs of use.
4. Precise scale: The scale is laser marked to ensure that the scale is clear and accurate.
