The Sensitive and Fast programs excel in iron-contaminated park sites where pull-tabs and nails outnumber coins. Sensitive (program 2) uses XP's FMF frequency-addition platform up to 40 kHz with reactivity set at 2.5, giving strong target separation without excessive chatter. Fast (program 4) raises reactivity to 3 and switches to pitch audio mode with square-wave processing, speeding up recovery time between targets. Both programs handle mineralized soil well, ensuring you won't lose depth in tough ground conditions. Explore the technologies behind modern detectors to see how FMF frequency stacking improves target separation.
