NOTE: Always refill the hole you have dug, and leave the area as you found it.

7.6.1Digging Deep Targets

The SD2100v2 has unparalleled depth capabilities which will surprise experienced and new prospectors alike. If the target appears to be buried deeply, it will help to use the following technique:

·Use the cross-sweeping method to locate the target as accurately as you can. Scrape a hole about 100mm deep and large enough to take the coil. Keep testing the target location as you dig deeper and deeper. Be careful that the target is not in the wall of the hole and you dig past it.

·If using a Monoloop coil, turn the detector coil onto its edge, making it vertical, and probe various sections of the hole, listening for the loudest reading.

7.7Salty Environments

The SD2100v2 will find objects at great depth in salty environments, but interfering signals caused by the saturated salt or highly concentrated salt can not be completely ‘balanced out’. The 11” Double ‘D’ coil will give the best results in salty conditions.
