## Overlaps & pitfalls
- A scope used for hunting but with thermal imaging could fit both 8525.89 and 9303.30. Priority should be based on **main function**: if recording or thermal is primary, use 8525.89; otherwise, use 9303.30.
- Scopes for night use may overlap between 9013.80 and 8525.89—clarify whether magnification is used.
- No option clearly defines "digital" vs. "optical" beyond the thermal recording in 8525.89. Use the most defining feature: imaging type or function
