I can't remember all the brands First Texas owns, but Fisher is one of them. They are having an ongoing fire sale on all the Fisher models. Garrett owns White's now of course. But have never done anything with their tech except repackage the Goldmaster, which is still a viable machine for the purpose and the money. I think they probably bought White's just to prevent a Chinese outfit from using the name.
VLF is still VLF with all it's limitations. Nothing has changed there since forever. Modern simultaneous multi frequency machines do solidly out perform single frequency machines of days past though. Particularly in mineralized soil and in accurate target ID/discrimination at depth. And the newest PI machines are starting to have useful target ID, which is a big step forward IMO. I don't own a PI yet though. The prices on PI's are still too precious for me. They do punch through mineralized ground and hit on gold nuggets much deeper than any VLF though. I'll own one eventually.
