GROUND BALANCE PROCEDURES
Before starting a new scan it is recommended to check your readings from your ground balance location
Fig. 1
1. Magnetic North to South is your recommended direction of scan within the Northern Hemisphere. It will be the exact opposite if
scanning within the Southern Hemisphere. (Fig. 1)
2. First lift your antenna off the ground a minimum of 2". Normal setup of a new scan. Open software, click on File<New<set time for
scan at 2 seconds<name scan file or leave default<make sure at this time your antenna is pointing in the direction you wish to
scan<press ok at this time and allow system to self ground balance. (Refer to picture Fig. 2 above for direction)
3. After ground balance is executed you will need to do a minimum scan (2 seconds). Walking slowly until your 2 second scan has
completed. It is not necessary to pay attention to what displays. You are only doing the scan to have a reading from your ground
balance point.
4. At this point you will want to click quit. You will not be doing anymore scanning at this point. Click on View at the top of your
software screen and then click on the show data under cross hairs tab. Another window (Locational Data) will pop open with data that
we will use to determine your ground balance point. You will want to use the data from the Data value Line. Your goal is to obtain
the lowest ground balance number you can. Closest to 0. A recommended scan is nothing stronger or weaker than +/- 100. You can
see by the data value picture we are at -4. That is a good ground balance point which will help us to see weaker targets such as natural
veins, weak pay streaks or even sub surface anomalies.
5. You will need to make your exact ground balance point for your scan in the middle of your initial 2 second verification scan, this is
the optimal spot. Refer to Fig.6
6. Your ground balance is not complete just yet. You still need to maintain the orientation and direction that you ground balanced in.
(Refer to Fig. 3-4) If you ground balance heading West you must maintain that direction during your scans. It is the same if you do
multiple rows with the same scan. You must maintain the same direction with the antenna at all times.
