I never use notch out 97-99. Most of these guys are coin hunters. If you are,a relic hunter and enjoy finding and digging trash pits and huts, you need to hear as much iron as possible. If you just want to surface hunt for bullets and buttons, sure use notch.
Exactly right. If your hunting relics then these notch settings are not for you. These settings don't affect depth just quiet things down in TID# areas that you don't need to hear targets in.
