11 x 6" Monoloop coil is extremely sensitive to smaller gold and still very stable over the ground. Ideally suited to cleaning up those previously worked patches. Better sensitivity, more accurate, able to locate both large and small gold nuggets that other coils miss. Small closed or solid design makes searching rubble strewn ground a breeze, no snagging. Ideal for working in tight bedrock areas and also areas with thick scrub.
