Hi David,
You have done a lot of work to produce these videos and I think that there may be other target combinations that change or don't change target IDs using the HF2 coil with different frequencies for target recognition since the HF2 coil combined with Deus 2 does not have normalized target IDs. Even Deus 2 with the original FMF coils have some target ID variation which you have shown in your past videos but not as much as the gold vs canslaw target ID differences you have been noting in your recent static and wild target detecting videos.
A similar technique could be used on Deus 1 when the HF coils came out using adjacent programs set to different high frequencies since the HF coil target IDs could not be normalized either.
I hunt for gold jewelry a lot, like at least 2 to 3 hunts a week. I end up with something gold at least once a month sometimes more. This year has been a little slow but I missed a couple of months due to a family illness.
I hunt with the 11" FMF coil most of the time because I want more coverage and depth. I have used the HF2 coil a couple of times for large area gold jewelry hunting but that is not something I would do often so respectfully, your method would not be of interest to me. Sure I sometimes dig can slaw that sounds really good and has the right gold range target IDs using the FMF 11" coil, like today when I was hunting a soccer field and was mostly concentrating on the audio responses produced by US nickels. I dug 17 nickels, 3 pieces of canslaw and one oval pull tab......no gold rings unfortunately.
Most of the time using Deus 2 and the FMF 11" coil, I can consistently distinguish a US nickel from a similar tone and target ID pull tab. The gold rings I find also have more similar audio characteristics to US nickels than they do to undamaged pull tabs. Attached is a short 30 second video I made back in early 2024 kind of demonstrating this. I wish I had recorded the audio from XP headphones instead of the remote external speaker which you also have noted, does not have the same sound quality as the XP headphones. See if you can hear a slight difference between the target's audio qualities? The targets under the gold pans that have highly iron mineralized dirt in them are an oval pull tab, gold ring and US nickel. See if you can put them in the right order from left to right.
I can hear this difference or at least the audio quality I listen for on gold rings in some of your recent videos too. Others have mentioned this ability of Deus 2's audio nuances on other forums in reply to some of your posts and you have dismissed that possibility. I can assure you that the difference is learnable by most people. It just takes practice and not just on static targets but also on lots wild targets.
Unfortunately, random shaped canslaw that has similar target IDs and audio pitches to US nickels and gold rings is not easy to to distinguish by audio except when it is very close to the surface. It can have a very brassy , distorted audio near the surface and nickels and gold rings just don't sound like that from my experience.
As far as saving time, I actually carry my digging tool (usually a long flat bladed screwdriver) and my pinpointer in one hand and swing with the other. Using the FMF 11" coil I don't have to investigate the target for long at all if I am listening for a nickel vs gold ring vs undamaged pull tab. I just takes a couple of seconds, a quick look at the target ID stability and I am digging or not. A surface to 6" deep US nickel takes me less than a minute from start to finish.
I am really enjoying the HF2 coil with Pitch 2 audio for bark, sand and gravel playgrounds and volleyball courts. Using Pitch 2 audio at 53kHz is dig it all but it has really paid off so far.
XP really improved FMF Goldfield's hot ground handling and sensitivity combined with the HF2 coil and Pitch2.
Your work on these videos helps anyone that wants to really learn the intricacies of Deus 2 and the new HF2 coil. Thanks for doing them.
Confirmed gold targets found since January 2025 on land. No fresh or saltwater beach hunting.
