Jimmy Sierra Bigfoot Coil

Its so Good that some clubs have tried to outlaw it in competition Hunts...
Covers up to 5 X more Ground in one Sweep!

The theory behind the design is called "differential" loop geometry. That is to say, the front half of the loop is positive while the back half remains negative. This allows for better canceling of ground mineralization and ease of pinpointing. All round loops send down a signal in the shape of a cone.

At the maximum detection depth of the loop, this only covers an area about the size of a silver dollar. The Bigfoot sends down a signal shaped like a windshield wiper blade and in the discriminate mode, covers a path equivalent to the length of the loop (eighteen inches).

In the "all metal" mode the Bigfoot detects from the front half of the loop only. This characteristic makes it possible to pinpoint very accurately. White's Eagles and Spectrums have a special setting called "absolute value" which allows for detecting on the full loop in the all metal mode as well.

The Bigfoot attains depths about equivalent to an 8" diameter loop. Its main advantage is that it covers up to 10 times the ground in one sweep and is ideal for searching large areas, such as beaches, ski slopes, fields and parks.

The Bigfoot is showing up in competition hunts across the country, even on plowed fields in England. It is designed for use on all White's DFX, MXT, XLT and Prizm models
