SEARCHCOILS
The Infinium LS comes standard with a 10" x
14" Power DD searchcoil. The DD coil configuration
couples with the API technology of the Infinium LS
make it the most powerful detector in mineralized soil.
In areas where the ground is low in mineraliza-
tion, the optional 10" x 14" mono searchcoil is recom-
mended. In these ground conditions, the mono coil
will outperform the Power DD.
For smaller targets in low mineralized soil,
choose the optional 8" mono searchcoil. It provides
easier maneuverability than the 10" x 14" mono.
For underwater hunting, choose your searchcoil
using the same criteria as land hunting. Consider the
level or mineralization of the water and/or the soil
at the bottom of the body of water. For example, in
saltwater, the Power DD is the best choice. In fresh-
water, however, the mono searchcoils will perform
better. Another criteria would be the size of the target.
Generally speaking, the smaller the target, the smaller
the searchcoil should be.
