The key to how the AML detects PVC/PE pipes and to identifying the size or length of a pipe is to understand how its radio frequency detects buried plastic and other objects.


Holding the AML's handle parallel to the ground, scan the area of the suspected pipe or buried object until one or both of the AML's target indicators activate.


While the left or right target indicator is activated, rotate the AML until both LED target indicators light simultaneously, triggering the AML's tone and laser marker. This alert indicates that the pipe or object has been detected and that the AML is now parallel with the underground object.


With the AML in parallel with the pipe or underground object, you can now scan the entire length of the object's edge. As an alternative, utilize the "W" method of scanning by sweeping the area in a back-and-forth "W" motion, marking the object's location and run direction as it is tracked.

Factory Training Agenda

SSI strongly encourages new operators to attend a factory training session in Green Bay, WI in order to fully understand the AML's capabilities, limitations, and to learn and practice various operating techniques. Below is the agenda for the topics to be covered and their durations. Class format and/or focus can be customized for the client's


A short introductory session that explains how the unit works.

Advanced GPS Mapping

Mark your coordinates on the job site with advanced GPS tracking and export to other devices via a data file through the USB mini port.


Increase the accuracy and speed of finding sub-surface objects. A digital left and right meter hones the operator to the exact location of an underground object so it can be marked and tracked efficiently.


Designed to provide the highest degree of accuracy available, the AML Pro has 32 individual sensitivity settings that allows the user to zero out unwanted feedback and focus directly on the object itself.


Powerful USB flexibility allows users to export GPS coordinates, import the latest firmware updates, and connect to the auxiliary Lithium battery source.
