Great Vid! I thought it was spot on with my own personal use.
I was always impressed with the unmasking of a coin around iron with the vaq, but I'm right there with you there something fun about multi-tone, VDI and having a sense of what your digging. To me it's just an awesome feeling when you see that VDI jump up to a target you would dig when you can hear the grunt of iron nails all around it.
I believe (in my experience) most gold targets are notched out around the mark before the nickel, which creates a bit of problem in trashy sites because if you want the gold your digging on solid tone alone and unfortunately for Tesoro users that means digging more trash. This was always an issue for me at parks I dug some rings but it was difficult to not dig pull tabs, can slaw, bolts, etc..
The one advantage I always felt comfortable just keeping the Tesoro in a hot truck driving around or while I was at work all day. I'm a little more nervous/protective about the NOX with the screen.
For me it was either sell the vaquero, buy another dd or smaller coil for it, or buy the Nox. I chose to sell the tesoro and by a Nox 600 so I'm in the hole about $400. (Can't keep em all..yet anyway)
