This Hulda Clark Dial-A-Zap Zapper has a 1 Meg ohm potentiometer and knob added to the circuit so one can dial frequencies from approximately 80 Hz to 30,000 Hz. You will need to connect a multimeter with Hz setting to see output frequency (meter not included - buy at Radio Shack). The Dial-A-Zap circuit is built into a standard electronic project box enclosure that has a sliding battery door on bottom for easy battery changes. Output bolts are marked blue for ground and red for positive output. A pair of alligator clip cables, 9 volt battery and Zapper Basics set up manual is included. Advanced users: Order a North Pole Speaker (sold separately) to experiment with the 1000 Hz setting as seen in Dr. Clark's "Prevention" book.
