Are VLF & PI Coils Interchangable?

[Terry Soloman]

"In a really basic sense, both are coils of copper wire, but the designs can be different, the electrical characteristics (inductance, resistance) are different and even the plugs are different. So if the detector is looking for a certain inductance and resistance and gets something else you can potentially fry circuits. So no, coils are not interchangeable between PIs and VLFs, even coils from VLF by different makers cannot be swapped (like a Fisher coil on a Garrett)." - Chris Ralph, Author of "Fists Full of Gold."

Was that you I saw with the WOT on their smoking Sand Shark?

At first thought you were asking. I should have known better! TTC

Terry, you have a stable FULL of Tesoros then, BAM, a Minelab! Is there a message here? I'm not all that familiar (sorry) with the Tesoro line but aren't there any PIs in their line? Obviously, you are covering all the bases. Question: What is the purpose for the Minelab? Balance? You, among a few others, can call yourself an Arizona expert.... home turf, so to speak, so the Minelab, I'm sure, fills a certain niche. May I ask for a critique of the pros and cons of your decision(s)? TTC

Hi Terry! Yes, Tesoro does have a PI in their line, the Sand Shark, but it is really made for saltwater beach and SCUBA diving, and that is what I use it for. The Minelab GPX, and the new GPZ machines are designed specifically for gold nugget shooting - and no other detector even comes close to matching them - none.

For me it's so important to use the right machine in different types of detecting, because I don't want to waste my time and energy. I don't recommend that just anyone rush out and drop $8,000.00 on a metal detector, unless they have an honest shot at recovering their investment. I have made my money back in gold nuggets and deep silver coins with the GPZ, that were too deep for the Tesoro Lobo Super Traq, or the Tejon.

I just like to have the best "clubs" in my bag for whatever the course throws at me.

Tnx, T, for the reply! TTC
