The 1280-X is available with either the standard 8 inch “Spider”
coil or the 10.5 inch “Spider” coil. As a general rule, the 8 inch coil
is preferred for tight spots, fast moving surf and high density trash
areas. For normal conditions however, the 10.5 inch coil will cover
a little more ground with each sweep and will give slightly more
depth 5 to 20 percent in air, less in soil, depending on target size
and mineralization. The most noticeable depth improvement will
be on large targets in non-mineralized soil.
The coils are not interchangeable since each instrument is
factory tuned to each coil. However you may have your 1280-X
retrofitted by the factory, phone or write for detailsWięcej tutaj:
