Classic 5 ID 
The below modifications do wonders for the new Pro's added target enhancement boost modification.

Ground Balance: This will give you the ability to externally adjust your ground rejection as conditions warrant. This will aid in depth.

Threshold: This gives you a external adjustment of the threshold level you hear in the all metal mode, and ground balance procedures. Set properly to just hear a soft tone in your headphones will aid in finding those deep targets when operating in the "all metal" mode.

Boost: We "Tweak" the sensitivity a bit while we have it apart on the bench. This will give you a  gain over the factory settings of about 2" to 2.5"

"NOTE" This may void your warranty, if it is still in affect.
