The DD (Double-D) coil design virtually eliminates the need for ground balancing adjustments when transitioning between mineralized soil and neutral ground. The DD configuration creates a detection field that reduces sensitivity to ground minerals, providing more stable operation in challenging soil conditions. Impact operators working relic sites with red clay and iron-rich soil report fewer false signals and more stable target ID compared to concentric coils. The IM24 maintains ground balance automatically across soil transitions, a practical advantage when hunting along creek banks and field edges where mineralization varies. This enhanced performance in mineralized ground makes the coil ideal for relic hunting and coin shooting in difficult soil conditions.
