The first page in the Blunder Location Window allows you locate loops that may have a blunder in them. The page shows a list of each loop in the cave and detailed information about the errors in each loop. This tells you which loops have large survey errors that need further analysis.

Once you have chosen a loop for further analysis, you highlight the loop in the list and press the "Analyze Loop" button. The program will then analyze the loop, looking for clues that can tell exactly where the error might be. This information is displayed in the remaining pages of the tool. |

It is often useful to make changes to the data while you are trying to fix blunders. To make it easier, you can press the "Edit Survey" button and Compass will open the Editor on file and survey where the closing shot occurred.

On the other hand, all the shots will probably be in the same file, so you can always open a different survey while the Editor is open. |
