The SP22 coil requires no firmware updates or special settings changes on the Simplex+ detector. Once you attach the coil using the included mounting hardware, the detector works with your existing sensitivity, discrimination, and ground balance settings without any configuration needed. You may want to re-ground-balance after switching coils if you're hunting in mineralized soil to optimize performance for current conditions, but no detector adjustments are required to begin using the SP22. The installation process is straightforward and takes just minutes to complete.
