Ok, first about analog being gone.
My first detector was an ace 350. Not nearly the top of the line from that company, but it'll make sense at the end.
I loved that detector. Didn't know anything else. Had alot of fun and found alot of coins.
Then I stumbled onto a Tesoro forum on another main forum. I was curious so I bought my second Detector. A 8" compadre.
Well, I was shocked at how fast it was. My 350 in comparison seemed dog slow. I onow at the time the at pro was faster, but almost $600 at the time. The compadre was 160 and I still think it's faster than the at pro.
But I digress.
Modern machines can definitely be as quick as an analog, to your understanding. I love my "fancy" digital Turkish machines. They are incredible and cost way more than they do nowadays and I'm still happy with them for what I paid. But I'll say this.... I still have an incredible love for Tesoro.
And for the price of the compadre or Mojave, they can't be beat by anything in their price range.
Personally for your dilemma, I'd go with the Mojave.
I modded my cibola and I'm incredibly happy with it. But. The process of modding it was nerve racking. It ended up great but if I messed it up I would have had 2 choices.
Throw it away or send it in to be put back to stock.
The cost would have been $50 to send it in for a look. Depending on any damage to the board or components, it could have cost me another $150 on top for parts and labor.
So in that situation with the cibola that cost me $180 used, it could have ended up costing me 320 which at that point I may have well bought a Cibola new lol.
If you're great with electronics then you may be fine. But for the cost of a compadre used (may have also been screwed with internally like many used compadres are, by people who want to spend a little and come out with a powerhouse) plus the cost of what you need to mod it and the chance to screw it up, I'd go with the mojave.
Back when I was considering modding a compadre I found the Cutlass umax 12 khz (not Cutlass II Micromax 10khz) which before the mojave was a modified compadre with changeable coils. Even then, after the cibola mod, I didn't want to go into a used compadre.
Long story even longer than it is already, if you want a compadre... Buy one new with warranty and leave it. If you want a compadre with changeable coils and sensitivity as well as a ground switch that from what I've been told handles all but the worst conditions, then buy the Mojave new and have the lifetime warranty.
I personally feel, after buying new and used, that the lifetime warranty is worth half the price of the new detector with warranty. If you are shopping used, half price or less is all I'll pay to lose the safety net of the only lifetime warranty in the hobby.
Sorry that went so long and I hope you got something out of it.
