Magnets in manual demining
The GICHD's Manual Demining Study included comparative trails of different manual demining tools and equipment. These trials established conclusively that the use of simple, powerful magnets increase the speed of metal detector clearance dramatically wherever there is metal "clutter" in the working area.

Devices offer a magnet-clip (SKU3027) that attaches to any sharp-edged tool.
It is easily moved from side to side for right or left handed
use. There are powerful magnets on both sides of the clip so that
the back of the tool can be passed over the ground (without touching)
to attract any surface fragments. If that fails to find the fragments,
the spoil is tipped over the magnets as excavation is carried
out and ferrous items adhere to the magnets.

SD Blast resistant trowel.
Devices have also made a magnetic Brush-rake. The Brush-rake is increasingly
used to clear leaf-litter or mulchings from the area in front
of the deminer. With powerful magnets attached towards the rear
of the rake-head, the fragments loosened during the brushing are
collected as the rake is used.
During the GICHD
tests, the magnet Brush-rakes were so useful that they made clearing
in heavily fragmented area with a metal-detector just as quick
as clearing where there were very few fragments.

Our simplest magnetic tool now uses a strip of 8mm polycarbonate with neodymium magnets attached (SKU3028). This is brushed lightly over the ground to attract fragments.
Order number: SKU3028, Magnet stick.
WARNING: Magnets must not be used in areas where devices with fuses that may be subject to magnetic influence may be found.
