Our “Hole-istic” Approach
We not only “dig” history in a figurative sense, but literally, too. That is, we must dig a hole (“plug”) to extract an item. However, digging a small hole in the ground should never mean disturbing a property. The goal is to make it look like you never dug the hole in the first place.*
This video perfectly displays our technique:
*Occasionally, imperfect ground conditions, like very dry dirt that crumbles instead of clumping, mean that a perfectly replaced plug is impossible. Even then, however, we try our utmost to ensure neatness.
