Starting a survey

From the main menu select SURVEY The screen will display options similar to:

In this menu you can choose the name of the section you are surveying.

Section in this case means the section of the survey which can differ from the section of the cave you are working in.

In our example the section is called AA1. You can navigate from one letter to the other moving the slider to the right and change the current letter by moving the slider to the left. Once done select OK.

The menu will give you the choice of the direction you are surveying, IN or OUT.

IN means you are going from already surveyed stations to new ones
OUT means you are coming from new stations going towards already known ones.

Surveying a shot

To survey a shot:

pull the pressure plate lever
insert the line into the slot
release the lever
make sure the line is not trapped
slide the device to the beginning of the shot ( Entry Station)

Select START

The display will show a RED square:

At that point the device is waiting to be stabilized to measure the azimuth.

The display shows a BLUE or PURPLE square with a dot in it when the compass has measured the first azimuth.

You can now move the device along the line all the way to the next station. The display will be flickering that BLUE/PURPLE square indicating that the wheel is spinning and measuring the length of the line. The device measures the line in both direction allowing you to compensate for big diameter tie-offs. If the line is too loose the length reading will be incorrect.

When you reach the next station, select STOP

The display turns red waiting to stabilize and measure the second azimuth.

Repeat the operation …

Once you reached the last shot of your section select END

This will save the section. You are back to the main menu ready to survey the next section !

Cancelling / Retaking a measure

If you want to retake a measure, there are two possibilities:

Either you are still in reading mode ( BLUE/PURPLE background ), in this case just select BACK and you can retake the measure you were taking.
You finished the measure ( WHITE background waiting for next measure), in this case you can select UNDO to erase the last saved measure and take it again.
