| Jun 14, 2015 at 18:07 | comment | added | Quark | @Brian I would assume the answer is that you can't find the treasure, but as I'm pretty sure you wouldn't make this puzzle with that answer I'll be leaving this as a partial answer. | |

| Jun 14, 2015 at 17:53 | comment | added | Brian | I don't understand what you mean about walking over the point with the treasure, either. For instance, imagine the following scenario: when you are standing one spot to the west of the treasure, the pointer points NE. When you stand on the treasure, it points N. And when you stand one spot to the east, it points NW. Now, given that, how do you know you have found the treasure? | |
| Jun 14, 2015 at 17:50 | comment | added | Brian | Sorry, I'm still concerned. There are a lot of details that need to be filled in. First the pointer is not guaranteed to point in a cardinal direction (maybe this was unclear?) so you can't necessarily walk in exactly that direction. Do you mean to step in the cardinal direction closest to the direction of the pointer? Can you explain why you will "undoubtedly be getting closer"? Also, what do you mean by "varying greatly"? | |

| Jun 14, 2015 at 17:44 | comment | added | Quark | You get close by walking in the direction the pointer points to. If you keep following that direction you will undoubtedly be getting closer. Then, when the direction starts varying greatly, you choose a general area to walk in a circle. From the pointer you will know that it is in there because the pointer will point into that circle at all points on its circumference. I do agree that it may jump up to 120 degrees though so I'll edit my answer. | |
| Jun 14, 2015 at 17:40 | comment | added | Brian | Yes, the treasure is at a single point. But could you make your answer clearer? First, how do you "get close"? Then, how do you walk circles around points? Finally your last claim isn't right -- even if you're very, very far from the treasure, the pointer might still jump up to 120 degrees, because it can point up to 60 degrees to either side of the treasure. | |
