Go rebels,
Both HF coils can indeed turn (signals obtained using LF coils where iron tone was obtained on actual nonferrous) to tones that a user can actually decipher as nonferrous tonally.
Even some targets detected with HF coils ( depending on detecting scenario) can produce very borderline pitch sounding signals for actual nonferrous.
This can be caused by soil by a combination of either or and soil mineralization, shape of nonferrous, orientation, and or depth. Not to mention there is a separation and unmasking advantage provided too again depending on detecting scenario.
I sure haven't run all detector models. But it is my opinion right now, before any site can be declared dead of nonferrous no matter how mild or crude the soil in the site is, both round HF and elliptical need to be put in these sites before declaration can be done. There may be more detectors that should be out in there too.
Already can think of one (based on first hand accounts) Nokta Impact and just maybe Kruzer multi run in 20khz or 19khz respectively using likely both the smallest round coil and smaller football coil. Don't discount the Nokta Relic detector either- will perform in polluted sites and find goodies- based on my first hand accounts.
Sure an fbs type detector should be out in site too.
Me saying the above doesn't mean other models have their place in helping clean out a site. But Deus HF coils can get you places many other setups can't. I would like to see some head to head using XP GMP power wearing small coil go up against Deus and HF elliptical coil.
This new Deeptech gold combo sounds like it might be a good candidate to add here to the list for helping with this " declaration of site is dead". Obviously though this rating of dead could only be temporary with the arrival on new releases.
Here is a thread here about elliptical HF coil.

The mighty half dime.
Don't see too many posted as found.
I have found one with ellliptical HF coil.
Another gent has found 2 just this year using one of the Deus HF coils. Don't know which one, but I am pretty sure he was running 28.8khz when they did find half dimes.
Not to mention the smaller gold coin hoard found using Deus round HF coil,,,actually the gent may have left the majority of coins buried if not for the higher freq on HF coil.. Can't prove but it is a possibility based on the gent's story.
Think about this.
Wonder if the Vlf detector industry would have never made a detector running over 19khz?
We would have never knew what was lurking in some of our sites would we?
We would have indeed thought sites were "dead".
Granted using higher frequency does come with some disadvantages. One going the real small stuf will get nailed. But orientation, shape of nonferrous, and proximity to ferrous can make a coin sized, even bigger seem small (for actual detection purposes).
Wonder if we did the following experiment with the following assumed.
Give every detectorist in USA split 50/50 one each of the following.
One detector that can detect a 10" deep clad dime in medium minerlized soil.
The other detector can only detect a 9" deep dime in the same soil as noted above.
But this second detector can be swung on average 30 percent faster and locate the targets the above detector can locate(except for the deeper)
Assuming all detectorists in USA were indeed highly proficient using each model giving them.
And all detectorist post their finds (all) non junk.
What would we see if we reviewed the finds qty wise after a period of 2 years??
Would the deeper detector win out?
Or the other detector?
Just some thing to ponder.
