I picked up a Mojave in August to use as a travel machine and for finding our modern steel-core clad coins. It was my first Tesoro, and has quickly become my primary detector. It does great in nails, and handles wet salt sand better than I expected. I found two (Canadian) large cents on a small beach on Vancouver Island, in an area I'm pretty sure I'd previously gone over with my CTX (!).
For the price, it's incredible. When searching for targets of up to 6" or so, I absolutely don't feel outgunned if other folks are using CTXes, Deuses, etc.
I decided to pick up a Vaquero or Tejon for times when I'm going after really deep targets. A black Tejon with the 8x11 DD coil came up first on eBay, and I got it for a good-ish price. It arrived just as our first blast of winter did, so the next four-five months will be spent in anticipation :-). If it proves to be too finicky, I'll look at getting a Vaq.
But I expect to use the Mojo for a lot of my day-to-day hunting.
