Yes! you can super tune the Vaquero and it will go deep, but it loses most of its ability to discriminate past its normal depth not super tuned.
You can't super tune a Tejon, so it just does what it does out to its full range.
Now, for relic hunting this doesn't amount to much difference, but for deep coin hunting your just screwed "with the Vaquero unless the area doesn't have much Iron to work around".
I should have proof read my post better, sorry about that.
I had A Vaquero just before I got my Tejon, the "V" was nice but for me and trying to reach those 7" to 8" deep coins it wasn't happening, so I traded it for a Tejon.
Now, the Tejon's worse problem for me is the tiny stuff that it will hit on that other detectors just go right past, some stuff is so small that it won't set off the pro-pointer unless you touch it right on the probes shaft, it amazing.
