Choosing the Right Coil
The site I’m about to hunt has a denite bearing on the coil I will be 
starting out with. If it is a wide open area, I’ll likely put on a 9-inch 
Concentric coil so I can cover the area quicker than if I started with a 
6-inch coil. For those of you hunting in highly mineralized sites, or those 
wishing to cover even more area with each swath, you’ll likely opt for one 
of the 10.5-inch Double-D coils. If it is a cultivated eld, and I can see all 
sorts of broken glass and nails, I’ll save myself the frustration of target 
masking and start out with the 6-inch Double-D due to its superior target 
separation characteristics.
