Decided I'm not ready for old homesites yet, and went back to the park. I'm ashamed to admit... I actually contemplated stomping the new Tesoro into the ground (only for 1 second, thankfully). GD GB!!!
I spent the first 1/2 hour trying to ground balance the machine, and could not do it to save my life. I recalled my last time out (1st time use) that when you were close, you needed to make micro adjustments to the knob. So, same location today...significantly positive response...no problem, start adjusting, and adjusting, and adjusting to no real affect. Ok, no problem, maybe I bumped the knob in transport I'll start over.Found the middle point between upper and lower limits...started with very small adjustments again with no noticeable changes...started making larger adjustments (1/4 turns)...to no affect...so, of course, I went with bigger adjustments and when that didn't produce the miraculous result I was looking for...I did what any sane person would do...I started blindly and wildly turning the knob left and right, first a micro turn(nope) then 1 & 1/2(nope) then back 2 turns(nope) and forward again precisely 1. 97365 turns back toward where I just was(nope) and from some crazy reason...that didn't work either. So I stomped back to the car.
This little Tejon was getting a time out! I was convinced spending an hour alone in the back seat would bring it to it's senses. Oh, and just to be sure the lesson was learned, I brought his brother, the DFX from the car...I was secretly hoping he would peer out from the window and see all the fun that he was missing as we played in the grass. As luck would have it, there weren't many targets that held promise without needing to dig and I found my mind wondering a bit. Then like a bolt of lightning, it hit me...it MUST be EMI of some sort. Why else would the coil make a pronounced response when I brought it up to waist height from the ground??
With the guilt of this new revelation weighing heavily, I quickly packed up the DFX and brought him back. I hastily placed him beside his brother and avoiding eye contact with the little Tejon, slipped into the drivers seat. To temper some of the awkwarness, I announced rather loudly, that we were going to another park. I hoped that this news would smother some of the sadness and frustration I could feel swirling in the seat behind me. That worked...for about 9 minutes.
That was the point I had to pull into that rest area. The one with no obvious signs of EMI, no buried electrical, no cell towers nearby. I would just let him run in the grass for a few minutes to shake of some of the negative energy of this misadventure. I wanted him to enjoy pure freedom, without interference or restriction.To be sure...I left the cellphone in the car and the key fob (push button start on car...car knows when keys are close enough to start...must have some kind of transmitter??) behind and walked a few hundred feet to the lush grass in the corner. OK, little guy, here we are...go, be you, do your thing!! I was so thrilled at the thought of redemption for both of us. My euphoria was very shortlived as the scene played out nearly identical to the one just an hour or so before.There was one slight difference this time though. Now, my frustration began to morph into determination. I went into methodical robot mode.
I inspected the coil(fine), wiggled the cable at the coil(fine), unscrewed the cable and reattached( restarted, no change), pulled the batteries ( restarted, no change) disconnected the coil and attached another (both are brand new), (restarted, no change)...WTH is going on I moaned aloud!! And that's when I heard it...just a faint little whisper, but unmistakable..."you're doing it wrong". WHAT

impossible, I've read hundreds of threads, I bought the book, I can't be doing anything wrong!!!
I still can't be sure who's voice it was, that forlorn little Tejon just sitting on the ground looking wholly unloved and dejected...was it forest fairies just within the treeline a few yards to my right, or was it that buried quarter nearby scared of the thought of spending eternity all alone?? Regardless, it had a certain ring to it and I had to accept it to be truth. I can't even begin to imagine how someone like myself with ZERO experience on this machine could be SO DAMN SURE that setting to the middle of the adjustment and working outward was "THE" way to this nirvana called "ground balanced". So Just to prove them(?) wrong, I was gonna do it different!
Went all the way positive (I think? My soul was shaken, how can I remember positive or negative) made a about 1/3 turn adjustment...BAAAAAMMM, a change...now dazed and confused, I somehow managed to execute 2 flawless micro adjustments, and the angels started to sing! I was at one, with the earth...that sweet hum of contentment wafted up through the coil and my little Tejon and connected to me through the headphones.
Now I know some of you are thinking " Wait, you need to have GB adjusted slightly positive or you are losing depth"...guess what? There appears to be a quite a chorus of others, saying just the opposite, LOL. So, in the absence of any links to sources to anything that even remotely resembles "scientific proof", I'll let the woods/ground fairies and my little Tejon buddy figure that out in due time.
EDIT: since this is the "biggest mistake thread" I'm a little disappointed to see that none of you managed to point out that me thinking I might know everything I need by doing "some reading", might be my biggest mistake. You guys are awesome, so I'm willing to overlook this and will try harder to learn from you all!
