Thanks for all the response. This is getting tough but there's probably no wrong answer here.
Squirrel1,
One question though, the test you did with the indian head penny where it was below and off to the side of some nails elevated on a small box, the Elliptical couldn't see it but both 9" rounds gave a good signal. Why couldn't the Elliptical see it?
O
Probably due to to shape of coil.
Remember the elliptical is flatter on the sides, vs the round.
I can say this with certainty.
Using elliptical coil at 28.8khz, a user will find some nonferrous off to the side of shallower iron around 5-6" ,,,nonferrous targets can be anywhere from shallow to around 10" deep.
No bs here,,and you try to locate these with round HF or round LF coils,,,some of the targets you will not hear tonally,,,or if you do they will be sounding like iron tones, basically being so compromised tonally,
Here may be a good way to explain this elliptical coil around iron to many other smaller coils.
If we take a square wave,,,many other smaller coils this square wave would be freq wise narrower (this span would denote how close iron could cramp a nonferrous (line of site when viewed above both iron and nonferrous target) and the amplitude of square wave (denoting depth of detection of nonferrous) would be shallower. (This would include coils like 4x6, round 5", round 5.5", 4x7" elliptical coils.
But this Deus elliptical,,,the square wave freq wise would be stretched a little,,,but the amplitude (denoting depth of detection) would be greater.
This Deus elliptical coil just might be for its size one of the deepest on the market,especially in minerlized soil.
This coil IMO can find things nonferrous in a site loaded with iron behind any detector/coil setup Vlf wise.
