question about TGSL design

[djmartins]

All the ads for the Golden Sabre brag about the notch filter and the TGSL design has taken it out.
Is it not useful or is it rarely used in the real world?
Why hasn't someone done a board for the TGS with the notch filter?
Surely the notch doesn't add that much more complexity to the design that make it necessary to remove.....

The answer is in the name ... TGSL, which stands for Tesoro Golden Sabre Light. i.e. it's a cut-down version of the Tesoro Golden Sabre.

In reality, the notch filter can be useful if you're trying to reject a particular target, and are prepared to overlook the possibility of missing some good signals. Most detectorists tend to ignore the notch filter, and set the detector for minimum discrimination, just enough to knock out small iron.

I did understand what the name stood for but failed to see much gain in removing the notch from the design.
I see, so you are saying it isn't used all that much so taking it off is no big deal.
I live in the southeast USA so I'd likely be hunting coins, civil war junk, and that sort of thing, so I do believe that a VLF detector
is what I'd need though there was a gold mine the next county over and some people do get some gold out of local streams.
If I went for the gold in the streams am I correct in thinking a waterproof PI detector would be best and the VLF for all the other stuff, like a TGS?

If you really want the notch filter, then you can always build a clone of the Golden Sabre.
You could use the TGSL for both coin and gold hunting, as long as the ground is not heavily mineralized. The bottom line is whether you can ground balance the detector in the area of the gold mine. If not, a PI is the way to go.

Thanks for the info, I may just do that.
The gold mines are a touristy type business but there are legally accessible parts of streams in that area people pan for gold.
The hardest part of the whole deal around here (and anywhere I bet) is getting permission to metal detect in the choice locations.
