The maximum depth on coins with a BigFoot is usually only about 4 inches. The depth is limited by the coil being so narrow. It gets about the same depth that a 3" to 4" coil would get. To get maximum depth you need to run the gain or sensitivity at or near maximum. Air tests will show greater depth but actual, in the soil depth isn't so great. The BigFoot was designed to get recent coin and jewelry drops and it's benefit is the greater coverage it provides.

I kept my XLT for use with the Bigfoot and it still pays its keep. Six inch is about maximum if settings are maxed out as Tom suggests. Practise the correct sweep speed on a few targets and if you bought secondhand it doesn't G.B. in the same way as other coils. You need a forty five degree slope when the ground setting is completed.

I use the BF on my DFX and depending on the soil I can get about 5 inches in the dirt here and maybe 7-8 in sand. Target size plays a lot into the depth it will see in the ground. To ground balance you have to tilt the BF at a 45 degree angle and use the edge farthest from your foot to touch the ground, otherwise the ground balancing will be off. The whole length of the BF is a working coil when your sweeping the ground and when you pull your trigger to pin point, the back half of the BF goes dead and you use the front half as your pin pointing half.
