How are SnagPod specimens assessed?

After testing, SnagPod specimens are graded from 1 to 5 to the nearest half a grade for appearance, in a viewing cabinet using the descriptions in BS 8479.


SnagPod reference photographs (set of 9) may also be used for comparison to aid grading in the viewer.


ProView – exclusive to James Heal - is pre-loaded with SnagPod reference photographs for easy assessment.
