Oh can I ever relate to this!  I, too am cursed to digging foil for a long time.  I frequently hunt a old large park that is full of trash.  One day I hit a spot where I.’ve pulled several pieces of silver, when I hit a solid “1” that appeared to be kinda long and shallow.  It didn’t give the iron grunt, but I wanted to ignore it.  I actually walked away but curiosity got the best of me.  I plunged my digger in and was couldn’t believe what was hanging from the plug.  I sliced it in two, but I quickly found the other half. It’s plated, but sure made me aware of what I could be passing up.

My 15” coil arrives tomorrow so I was searching forums for tips/problems before I start using it.  When I read your recent post, I thought I’d share what I’ve learned.

The jumpy VDI might be reduced if you back off on the recovery speed (RS).  I found this when using the 11” coil, when I can, I back off the RS when swinging over a jumpy high tone and it does calm down.  Try ithis with a variety of high-tone targets and see if it helps.  

From what I’ve read, most guys swinging in test gardens find that it is necessary to use a RS of 4-5 with the 15”.
