3
Move your cart forward. Data only gets collected when you move the cart forward.
4
Once you start seeing hyperbolas on the screen, pull the system straight back along your
survey line. You will see a vertical line (the backup cursor) scroll along your data.
When that vertical line is right over the apex of the hyperbola, the center of the antenna
is over that target.
Note:
When you pull the Mini straight back, and if you configured AutoTarget On, the Mini will interpret targets
by placing yellow dots on the targets.

The center of the antenna is directly under the Mini. After marking the location of the target on the ground using
the laser (if configured On) at each side of your cart as a guide (or the groove on each side of the cart as a guide if
the laser is configured Off). Push the cart straight forward or move the cart to do another line scan. No data will
be collected until you have passed the spot where you started to reverse.

If you wish, you may calibrate depth (optional). Match the target location in the data to its location in your survey
area. Drill down to that target and measure the depth.
a)
Press Enter “Depth Cursor” and backup the Mini to bring up the crosshairs and set them over the target in the
data.

7 Other Options
• Press and HOLD Ï (New File) to save your current scan. If you have configured Save Prompt On, you will
be prompted to confirm the save. Press Ï to Save, Ð to not save the data. If you have configured Save
Prompt Off, it will save automatically.
• Press Í to place a user mark in your data.
• Press Î to exit. If you have configured Save Prompt On, you will be prompted to confirm the save. Press Ï
to save, Ð to not save the data. If you have configured Save Prompt Off, it will save automatically.
Helpful Hint: Make a sketch map of your survey area with immovable objects as reference points. Sketch in your survey
files, note the start and stop points, direction of travel, and file name on the map. This will make it much easier to relocate
your targets after the survey.
Helpful Hint: The top of a target is generally the middle of the first positive peak for metal targets (rebar, tensioned
cable, wires in PVC, conduit). If you are working in a grayscale color table, the positives are white. If the utility is air or
gas filled (empty PVC, voids) the top of the target is the middle of the first negative peak (black).
Please refer to Appendix C for examples of the different types of data.

Appendix B – Battery/Charger Information
Your system comes with a two-slotted battery charger and adapter. It also comes with three international interchangeable
plugs.
• To charge your batteries, simply attach the adapter to the charger and plug in the
adapter. Insert one or both batteries. The batteries will charge one at a time. The bars
located at the top of the batteries will indicate how much charge is left in the battery.
• At times, you may wish to re-calibrate a battery. Simply insert a battery into the slot
on the left and press the RECAL button
•
LED Lights
– As the batteries are charging, the LED lights for each slot will do
different things.
• No Lights – No Batteries
• Green Flash – Fast Charging
• Green Solid – Fully Charged
• Yellow Flash – Recalibrating
• Yellow/Green – Recalibrated
• Yellow Solid – Standby
• Red Flash – Error
• If the charger remains plugged in and there are NO batteries in the charger, the charger will eventually begin to
“beep.” Since this can be annoying, it is recommend that you unplug the charger when not in use.
