Beach ground balance

When detecting on wet beach sand, it is best to select Beach Ground Balance (X-TERRA 705 only), as this will allow

a higher sensitivity setting to be used. To activate Beach Ground Balance, simply press the Ground Balance button,

then press and hold the Ground Balance button again until the Beach Umbrella icon is displayed on the screen. If you

want to detect all over the beach from the dry sand down to the wet sand, then it is easier to leave it in Beach Ground

Balance, and then set Sensitivity to suit the wet sand. That way, you won’t have to adjust the detector settings for

the remainder of the session. For optimum performance it is best to work the dry and wet sand sections of a beach

separately, which will allow you to operate the detector at its optimum sensitivity level. Tracking Ground Balance Offset

in the X-TERRA 705 should help here!

Tracking on the beach

Tracking can be an advantage on some beaches where the mineralisation levels change rapidly. One thing to remember

is that the Tracking speed when in Beach GB is very fast (approx. twice the speed of Tracking in normal GB) so you need

to use extra caution when investigating deep targets - if you sweep over it too many times the signal will diminish, and

can go away all together! Also, in high trash pockets on the beach, the presence of so many targets will upset the GB

setting, and you may experience erratic performance - so these sections are best worked with a Manual GB. The faster

Track speed in Beach GB can be a good feature to use in other areas, and may be an advantage in highly variable

goldeld soils, and some relic sites, but if conditions allow, the Manual GB is the preferred mode.
