What to check before buying
- Check the exact overall length and base width against the surface and the available working space.
- Compare the stated accuracy and whether it applies in both normal and inverted measuring positions.
- Confirm which vial angles are included and whether the base is magnetic for the selected model.
- Read the pack contents carefully when an image shows multiple sizes, cases or additional accessories.
