Vintage Whites 6000/di Metal detector repair Intermittent operation

I decided to give Emi a little basic electronics troubleshooting training. Hopefully she found this interesting.
She and I enjoy the metal detecting hobby, so she is familiar with the instrument. She has a good analytical mind, so was able to reason out the problem. I was impressed how she took this task on. Someday Emi will be heading up D-lab. These are old detectors, more than 30 years, I believe. I own a 5900/di Pro. It is the best detector I have ever used. Yes, they are a bit heavy, but the performance cant be beat. I hope you can appreciate this video. Trying to spread what knowledge I have to future generations.
