This 8" Spider Search Coil with 7 foot Cable was made for use with Fisher 1225-X, 1236-X2, and 1270 series of metal detectors.
In general, larger search coils will give better depth with larger targets and better ground coverage. However, sensitivity to smaller objects may be sacrificed. Smaller search coils will offer greater sensitivity to smaller objects and improved target separation in trashy soil. All Fisher searchcoils are electrostatically shielded and waterproof, plus all Fisher accessories purchased separately (including coils) carry a 90 day warranty
from the factory.
