That line is a great example of Lance’s pride in his craft and his adherence to an unspoken detectorist’s code. When he says, “I don’t detect spoil heaps. Vulgar,” it’s more than just a throwaway comment — it’s a statement of principle.

Spoil heaps, which are piles of excavated earth left behind by others, can sometimes yield finds missed in the initial dig. But for Lance, rummaging through someone else’s leftovers lacks honour. It’s shortcutting the process — the patience, instinct, and intuition that seasoned detectorists like him take pride in.

The comment reinforces Lance's image as a purist — someone who respects the quiet dignity of the hunt, and who sees detecting as more than just a way to find treasure. It’s a philosophy, a way of life, and Lance sees himself as a custodian of its traditions.

It’s also a little funny — "vulgar" is such a grand word for such a small act, but that’s very Lance.
