Sinusoidal Technology

Can anyone explain to me how this is any different than a standard concentric search coil.

While I have no idea what you are asking about, I think you are confusing issues. Concentric coil is a design. Sinusoidal would be referencing a Signal so that would HAVE to ne talking about the processor

I see ...thought what I read was talking about a specific kind of coil or something about the coil's physical design that made it perform differently or more efficiently than a regular concentric....

"The 9x8 and the 12x10 are spoked coils that use Sinusoidal Technology(This made me think these specific coils were different specifically than a regular concentric: they definitely look different). This technology creates a detection bubble that works from the center of the coil to beyond its edges. These coils produce an infinite number of electromagnetic flux lines, which surround the coil and penetrate deep into the ground. As targets pass through the bubble, they start interfering with or breaking the flux lines. The detector reads the interruption of flux lines and a signal is produced. When you saturate the ground with these flux lines, you're guaranteed better sensitivity to smaller targets and more depth on larger targets."

If that's what it says, I'd avoid it. That's the worst case of electrical mumbo-jumbo I've seen. ALL coils generate lines of magnetic flux that penetrate into the ground. In effect, the transmit coil is the primary of a transformer. The metal object is the secondary of that transformer. The secondary emits a signal that is picked up by the receive coil. In a nutshell, that's it...that's how VLF detectors work, simplified. The transmit and receive coils are "nulled" so the receive coil doesn't pick up the transmit coil. The only difference between coil types is the shape, and how they are "nulled".

Yep, sounds like snake-oil charlatan gibberish. Please tell us what company is spouting THAT.

I bought a used Tesoro Golden Sabre II (a detector I loved back in the 90's)It came with the standard 8" concentric amd the oblong 10x12 spoked coil referenced in this post. So I already have it and it wasn't purchased specifically. I do think it should get a little better depth though just by virtue of it's larger size. That said, I haven't tried it out in the field yet.

That's depressing that a quality company like Tesoro would stoop to tactics like this to try to sell products. As for your question, yes, a larger coil will get you a little more depth. It won't be a lot, but sometimes getting an extra inch or so can be a big difference.

I'm much more impressed by Tesoro's engineers than their marketeers. I ignored all the advertising hype when I made my decision to make my first detector a Tesoro. Sadly, yes, they do have a junky sales spiel. They basically used verbiage that was somehow both overly-complicated and dumbed-down to explain how all metal detectors work.

It reminds me of the three months I once spent as an used car salesman. It was the worst job I've ever had by far. Have you ever thought about what it would be like to spend 60 hours per week in a building full of car salesmen? E-ville! In training, they instructed us to tell customers that the car they're looking at was built to withstand the whole weight of the car on the roof, so it would never collapse if it rolled over. All cars made in the last few decades were made to those specs by law, but that part didn't seem pertinent to the sales managers.
