Determining depth with the AML+
Once you have located the PVC pipe
or underground object, find its center
and mark its position on the ground, tilt
the handle of the unit downward until
the blade is at 45º, (figure 12-1) and
walk backwards until you find the top
of the pipe. Make a mark where the
laser indicator is located on the ground.
Measure the distance between both of the
marked points, this will be the depth at
where the PVC pipe is located.

1. Determine pipe’s center & mark the ground
2. Tilt the AML to a 45º angle*
3. Start walking backwards until you find the pipe again
- Make sure you located the pipe by scanning its edge 3’ to the right or left -
4. Mark the spot on the ground
5. The distance between both points is the depth of the pipe

Useful Tip:
if you tilt the handle downward until the 3rd nub from the battery cap is aligned
to the blade tip and they are parallel to the ground the blade will be at 45º.
