System Setup; Cart Assembly - Geometrics MetalMapper 2x2 Operation Manual

3. System Setup

The MetalMapper 2x2 system is packed and shipped in a collapsible plastic crate (P/N MM2x2
Crate) secured with banding. The crate dimensions are 48 in x 44 in x 36 in with a packed
weight of approx. 350 lbs. (shipping weights and dimensions may vary). Foam inserts are cut to
protect and secure the instrument during shipment. See Chapter 10 for more information on
packing and unpacking the system from the shipping crate.

3.1 Cart Assembly

The 4 transmitter coils (Tx) and 4 receiver cubes (Rx) are attached to the sensor platform with
plastic bolts. These items should not be removed or replaced unless instructed to do so by the
project geophysicist. The Rx cubes and Tx coils are covered by a piece of plastic attached to the
sensor platform. The cover should remain attached under most conditions. There is a cable
connection facing the rear of the sensor platform. The sensor platform cover should not be
removed without consulting Geometrics for instructions on how to remove it without damaging
the cable connection.
The axles are attached to the sensor platform with the axle mounting brackets. Slide the axles
through the brackets. Attach the wheels and spacers to the axles as shown below. There are 3
plastic spacers and 1 washer placed on the axle between the wheel and the hub. The wheel can
be secured to the axle on the outside with the small nut and bolt included, or with an optional
zip-tie.
