ICON DATA REAL TIME 2D & 3D LOGGER FOR GROUND PIONEER GROUND PIONEER is data logger ready. Connects to ICON DATA real time magnetometer & metal detector data logger. The data logger connection is the headphones jack of the GROUND PIONEER.
! Use ICON DATA once you are familiar with the GROUND PIONEER operation Using the ICON DATA logger the sensitivity or depth penetration of GROUND PIONEER is greatly improved over working with the speaker. Scan the field at a normal pace and 2D & 3D maps of the scanned area are generated on a windows tablet PC or laptop in real time. No need to upload data later to a PC. Data logger is a useful aid to determine target size, shape and also depth reading for some cases. Before connecting the ICON DATA logger, ensure that the GROUND PIONEER operates stable, and it is setup correctly without any interference audio when it is raised or lowered to the ground surface.
! To operate with ICON DATA set GROUND PIONEER to “Semi” mode The ICON DATA and it’s tablet PC must be held away from the GROUND PIONEER frame coil during the ground balance procedure also during searching, to avoid interference.
ICON DATA logger connects automatically with GROUND PIONEER, without the need of a tuning knob.
3D scan of a box using ICON DATA
2 Procedure 1. Connect the USB cable from ICON DATA to the USB port it has been installed on your laptop ( read the full instructions on how to install the hardware – software ). A Windows XP-VISTA-7-8 laptop or tablet PC with Intel processor is necessary. 2. Power on your laptop computer 3. Double click the ICON DATA software icon, wait to start the software 4. Click Options. 5. Observe the field you are going to search. According to your starting position you have to scan it in parallel tracks (sweeps) starting left or right. Then choose the suitable sweep direction for that field by clicking repeatedly the sweep direction arrow. Figure 1 6. Note the field again to realize it’s size. Select how many estimated lines you need to scan for covering it on sweeps. Then select how many points you have to make per line on points. Each point equals the size of the coil used. By making shorter steps the scan image resolution will be higher. Tip: select equal number sweeps and points. With large grids image resolution also gets higher. Figure 2. 7. For uneven ground that does not permit constant step pace: select manual data capture (then you have to click CAPTURE after a step you make, for the graphics to start appearing.) For flat ground that does permit constant steps: select automatic data capture, then select the intervals time. For example if you select 3 sec., after you click START, every 3 sec’s. you will hear “STEP!” and you have to make a step. The computer will make the graphics on screen automatically as you make your steps. If for example you selected 7 points, on the 7th step you hear “TURN!” - you need to turn to the next sweep line, left or right according your sweep direction, then walk 7 steps prompted by the voice and turn similarly…and so on 8. Ensure “auto scale data to full color range” is on and Op Amp Gain is 2. Click Set Gain & OK and exit Options 9. Move far away from metal targets, buried or not. Stand in clean soil withοut metals, cavities, voids. Tune GROUND PIONEER as described on the instructions manual, test to ensure that it operates stable without interference. Connect ICON DATA to the headphones jack of GROUND PIONEER, using the supplied cable. Start scanning! 10. After you fill up all the sweeps / points you will have the complete graphics image of the field. Store the data file by click on File / Save, otherwise it might be lost.
11. During the scan you can alter between GRID & 2D CONTOUR view by click on the bottom right of the screen. GRID view is a guide for your steps. 2D CONTOUR is more analytical for taget shape. 12. After the scan completes click on 3D for a 3-dimensional view. Please study the full ICON DATA instructions and practice to understand how to interpret graphics and the usage of the controls

6 ANALYZING THE SCAN IMAGE 1. Check that the scan image has a uniform base color on the background, this represents the ground. Usually in blue, and should cover most of the scan cells.
If not a base tone, or scrambled colors then either a user fault or not any targets exist on the scan see example. If by fault Ground Pioneer has not been setup with the ground correctly scan appears with repeating blue and red lines, see these 2 examples below.
2. Check the target to have a clear outlined shape without shades, and it’s size compared to your grid. Ground minerals appear either without a clear perimeter, either with shades or very large size. 3. Select 3D and compare the ground data versus target data. Ground data should be near zero for a good scan. A true target data should read high data.

Target data near zero often correspond to minerals
