Thanks for the feedback. Today, Bruce suggested we put two close together, and I said I would ask. I will tell him he is spot-on.
Question. Do we increase the search area or increase the depth first? There seemed to be no problem with either on this hunt and we will move on to an unfamiliar location – perhaps just a tad deeper and a slightly larger unfamiliar (but clearly defined) area. I will know the number of hides, but not their location.
Or, we can go back to this location, a familiar one, double the area, and increase the depth.
