Spectrum sweeps output multiple simultaneous frequencies targeting where pathogens live, and are convenient and powerful for killing. It is best to alternate sweeps with targeted database sets. Spooky pulse scans are most powerful and can detect early cancer, but are not as convenient as presets can be used directly for killing. The effectiveness of database sets depends on the accuracy of diagnosis, and a different strain may require trying another database set if no results within 2-3 days. For healing, biofeedback scans or targeted database sets are suggested as sweeps are designed for killing and healing works through frequency entrainment.
