What were some of the very last BFO metal detectors made?

Hi,
I have another simple beginner's question. What were some of the very last BFO metal detector models made (makers and models)? And when were they produced?
Thank you

I remember using them.

Garrett was still producing them I think into the late 1970's, even though their VLFs were taking off around that time. Likely some of the junk brand BFOs made it into the 1980s: Jetco, Relco, etc. There were a lot of small manufacturers around in the 70's that probably couldn't afford to keep up with progress and ended up dying a quiet death.

BFO was generally popular in the 60's & 70's. Garrett made one of the best (though I'm convinced it wasn't a real BFO), ending production in 1982. I'm guessing it was about the last to go.
