Great video as usual. What are you thoughts on setting up 2 identical programs and just changing the frequency, 1 high and 1 low to help identify iron. I’ve used this and it seems to work great but I do not see anyone ever posting about this. The only probelm ive seen is when a nonferrous target is close to a ferrous target then it might not help. I also know you have to rely more on the VDI.

Yes and adjust the pitch to 600 h. The change freq to check for iron works sometimes but be careful. I had a DEEP signal and there was a lot of deep iron at the site and I was using that technique when I first got my machine and I checked the signal and it didn't change tone wise from 11 kh to 4 kh so I thought deep iron falsing but dug it anyway it was coin at 9 inchs or so. Need less to say that was when I quit using that technique. I have come to the conclusion there are no absoulutes in detecting...BTW I did use it some on some targets and it worked but that one signal kinda broke me from it.
Thanks for the video! One thing I’ve found is a very high percentage of the time the 98-99 vdi with as you stated sounds forced than when you 90 it grunts away... deep iron.
Using a 4khz check next to your program helps.. if it stays high it’s prob iron. Drops prob a coin.
One IHP I dug in my nightmare training ground was a 95 (12 kHz) repeatable but week and 90 degree still there. Even in all the iron it was consistent.
My biggest complaint is rusted smashed flat crown bottle caps. In full tones sometimes wiggle back it will grunt and coil raising if vdi drops it’s a cap... but I still get fooled a lot by them.
