Check Backsight

Use this to check your backsight. FieldGenius will compare your newly measured value to the one that was stored for your current setup. You will be able to review difference and optionally update your current setup with the new shot to the backsight.

When you start the command you will be taken back to the map screen and the Measure Mode will be set to Check BS. You have two measure modes available when taking a check shot to your backsight. Please see the Backsight Measure Mode topic for more information.

Check Backsight Summary

When you're ready to record the shot press the Measure button on the instrument toolbar. You will be presented with a screen that compares your measured values to the ones that were stored for the current backsight.

Update Backsight

Pressing this will create a record in the raw file updating your setup and backsight record with the shot information from your check shot. Several notes will also be written to the raw file summarizing your shot. When you choose to update the backsight, a new OC and BK record is saved as well as the shot information. You will also see the word (Updated) which indicates that the user selected the Update button.
