GSSI Ground Penetrating Radar, GSSI Survey Cart Model 643

Original price was: $6,860.00.Current price is: $3,430.00.

GSSI Model 50400S antenna has greatly improved resolution performance over previous GSSI mid-frequency antennas, such as the Model 3105 (300 MHz). The Model 50400S can be used in continuous, survey wheel or static stacking modes. Model 50400S is a 400 MHz “smart” antenna. This antenna has a special chip in it that will work with the SIR-30 and future control units (not the SIR-3000 or SIR-20). This chip will identify the antenna to the SIR-system control unit so that the controller will be able to automatically load up the correct default settings. The 50400S will function with a SIR-3000, SIR-20 or any of GSSI’s previous controllers, but the user will need to manually set the collection parameters on the SIR-system.

GSSI Ground Penetrating Radar, GSSI Survey Cart Model 643

Model 643 Survey Cart Assembly Guide
Mobilizing your system on the GSSI Model 643 survey cart allows you to cover ground much more easily
and conveniently than with the conventional system configuration. The cart can accommodate the 270 MHz,
400 MHz, 900 MHz, 1 GHz, 1.6 GHz, and 2.6 GHz antennas. The 643 cart incorporates a unique antenna
capsule design that protects these antennas from the elements and renders the antennas weatherproof.
It also incorporates a survey wheel for high-precision distance measurements. Please read through the
entire assembly manual before assembly.

Capsule Assembly:

Place the capsule bottom into the frame and thread the nylon support straps through the buckles on the cart
frame corners. Each stitched line is 1 inch (2.54 cm) apart. The capsule bottom is a replaceable item and it is OK for it to drag on
the ground. You will extend its life by adjusting the nylon support straps so much of the weight is taken by the straps and the bottom
is just slightly in contact with the ground. If you are working in rough terrain then you should adjust the straps for maximum travel
to allow the capsule to follow the ground surface topography.

Wheel Assembly:

Attach wheels to cart frame. Line up the flat side of the “D” shaped axle rod with the corresponding flat part of
the “D” shaped hole on the cart frame. Slide the rod into the cart frame while keeping the blue button at the center of the wheel hub
depressed.

Insert Antenna:

Place either the 400 MHz (Model 5103) or the 270 MHz (Model 5104) antenna into the capsule bottom with the
arrows pointing forward. Then place the Antenna Locator Foam over the top of the antenna. The large foam block should be facing
forward. To use the Antenna Locator Foam with the 400 MHz antenna, simply flip it over so that the stepped cutout is facing down.

Handle Assembly:

Slide the handle bottom into the handle receiver on the cart frame. Flip the handle locking lever up to the
closed position to secure the handle in place (Step 2). You will also need to attach the SIR-3000 mounting bracket to the handle top.
The three screws used for attachment are already in the handle top.
