Operating modes 45
6.4 Tunnel Scan
This operating mode is used to identify tunnels, voids and caverns. To use this mode, it is necessary to
connect the Antenna for Tunnel Detection. If you do not have the optional Antenna for Tunnel Detection,
one must be obtained prior to using this mode. This is an extremely powerful function and can assist you
in identifying tunnels, voids and caverns.
After activating this operating mode you have the possibility to adjust the impulse mode setting. In
figure 6.8 you can see the corresponding sub-menu.
Please refer to section 7.3.3 (“Manual or automatic impulse mode?”) on page 80 for further explanations
concerning the impulse mode setting.
Then go to your start position and select the option “Start Scanning” (Green Tick) to start the
measurement. A message will appear and ask if you are ready to start your measurement. Rotate the
multi-function control knob and select “Yes”. As soon as you depress the knob, it is important to begin
walking immediately for the eXp 6000 is now recording data.
6.4.1 Scan Technique
When looking for tunnels, voids or caverns below the surface, the procedure is basically the same as
when looking for natural minerals. The primary difference is that the signal strength will be much
stronger and the typical coloration will be a darker blue.
