Hi Jerry:
Yes, some of the VDIs can off, so I guess if you're big on discrimination then it could be annoying. I don't pay as much mind to the VDIs as most people I think because I'm still a "Dig it all above 10" person with an attempt to ditch bottle caps screw caps, and big items. I hunt in a lot of places where there could be gold and I don't want to miss anything at all. (I ditch bottle caps by only digging dominant 22.5 above 40 though the other thread on 22.5 possibly being dominant in some conditions has me rethinking this)
The one weird thing is that sometimes the coil pinpoints off the front half and sometimes off the back. Still, I feel like for running along on sports fields and just sweeping up surface stuff, its a really fun and light coil. For days when I want to try to look deeper I'd use something else.
Hope this helps,
Tater
