That's how it seems on the void, it can happen on mountain photos, especially when high up on a ridge or peak. Void signals alone may or may not be important, really depends more on what else you pick up with it.
Doesn't hurt to check the spot, if you did find an entrance or void there, then the signals in the distance might be something else, perhaps markers pointing to the void. In that case, my interpretation of the signals wouldn't be entirely correct, need to check things out. At first the marked spot was my dowsed actual location, but checking more the signals go beyond there 1-2 miles. I'd at least check for markers in the distant area . Signals close to the horizon line can be either possibility.
"so you go further out in the field of view to be directly over it, depending how deep it is."
The white circle probably should be the place to dig, since it looks nearly to be on the horizon.....unless of course, the target would be off in the distance. If I check for entrance or opening (which is how I'd normally do it) after picking up a tunnel or other void hit, you can expect the spot to be where to check. Sometimes void signals turn out to be be nothing more than a deep tunnel like hole dug by people searching for or recovered a treasure.
