The Nokta IM19 coil provides effective depth on coin-sized targets in moderate soil conditions. Actual depth performance varies with soil mineralization, target orientation, and the Impact's sensitivity setting. In highly mineralized ground or saltwater wet sand, expect reduced depth compared to neutral soil. The IM19 is optimized for target separation and small-target sensitivity rather than maximum depth, so if your primary goal is deep silver in open fields, a larger coil may be preferable. For trashy parks, relic sites with iron scatter, and beach hunting where target separation matters, the IM19's performance profile fits the task.
