ETRAC-Red Dirt-Coil for the best depth

[david bull]

In most parts of the country a larger coil equates more depth.Here in the red dirt south,a larger coil just sees more mineralization and either lowers the sensitivity in auto mode or falses in manual mode.On the other hand,a smaller coil will see a smaller sampling(meaning less reflected signal)and would operate at a higher sensitivity and see more depth.Do any red dirt hunters have any input or experiences concerning bigger or smaller coils in our tough soil?

I have no experience detecting the south but have found in the red dirt mining areas of southern Utah, the 6" DD excellerator serves me well in ugly mineralization with properly set sensitivity, and a deliberately slow sweep. Yeah, there can be loss of depth but I consider it a nominal factor compared to not being able to hunt a spot in the first place. JMHO...

I have found, that on most detectors, a smaller coil will allow more signal/power with less falsing in most soil.This relates to the headlights in the fog concept where the light from high beams is just reflected while narrowly focused fog lamps will pierce the fog for a longer distance.
