Two-box prototype for the Rutus Alter-71 metal detector

This is a two-box prototype for the Rutus Alter-71 metal detector. The Alter-71 has a very good static mode. It is very stable. The two-box can operate over a wide frequency range. But here static mode and 5kHz frequency works best. The SAT setting is from 0 to 5. Tuning to ground works correctly and fast.

More details and a movie coming soon.
