They will gather intelligence, lay false trails and strike at their opponents suddenly and with determination.”

Dewdney, A. K. Scientific American January 1987.

A scanner searches for the opponent and hits hard, first stunning with a SPL attack then switching to a deadly DAT attack. Modern scanners are often large and fragile, scoring well against paper but losing to stones.

Blur Scanner

A blur scanner has a continuous SPL wipe and a scan in the same loop. The scan directs the wipe to anything found. After the main attack the scanner either falls through to a core-clear or alternatively switches to a DAT wipe. The first blur scanner was created by Anton Marsden in January 1996.
