Intended Use
Intended Use
The 2450GR is a ground penetrating radar system that detects metallic and non-metallic pipes and cables
buried underground. Following standard radar principles, the 2450GR uses a high performance
electromagnetic sensor equipped with electromagnetic transmitters and recievers to identify underground
utilities and transmit the location data to a portable computer where specialized software maps the location
site.
The unit is designed for operation in conditions typically experienced in earth moving and construction
work environments. Provisions may be required to operate in extreme temperatures. Use in any other way
is considered contrary to the intended use. The 2450GR should be used with genuine Subsite Electronics
components. It should be operated, serviced, and repaired only by persons familiar with its particular
characteristics and acquainted with the relevant safety procedures.
Any changes or modifications not expressly approved by the manufacturer could void the user’s authority
to operate the equipment.
This equipment is sensitive to the presence of external electromagnetic fields, which may reduce its
performance.

Survey the Site
Survey the Site
Consider the following when preparing to work at a survey site:
•
Gain permission to access pedestrian zones, interrupt traffic flow, etc.
•
Determine site accessibility.
•
Determine space available for cart.
•
Observe traffic levels.
•
Observe presence of parked cars.
•
Observe presence of architectural obstacles.
Inspect Visually
Make a visual check of the site for signs of buried cables such as:
•
recent trenching
•
buried cable markers
•
overhead lines that run down the pole and underground
•
gas meters
•
valve sights
•
drains or manhole covers
Acquire Utility Maps
Various companies produce technical maps of existing utilities. While some maps may be very generic,
they are an important tool for gathering and interpreting data at the survey site. The maps provide general
schematics of the type and position of the utilities managed or constructed by those companies.
Request maps by contacting the utility’s cartographic or planning office. Specify the street names and
areas of interest. Request maps well in advance of the actual survey. Types of utilities to consider are:
•
public street lighting
•
low, medium and high voltage electric cables
•
water supply
•
gas
•
telephone cables
•
sewers
