I have used a Compadre, a Mojave and a Vaquero at many, many places and from what I can see the Mojave works better than the others.
Thousands of hours with the Vaq and the Compadre, maybe close to 100 hours on the Mojave.
That would be in MY area of the SE with a decent amount of mineralization plus an insane amount of iron.
I mean really intense iron most everywhere including in the neighborhood lawns I hunt.
Here the Mojave works in a similar way seems a bit more sensitive than the Compadre and still retains all the Compadre's superpowers like being able to double beep on targets next to big metal objects.
In regular areas the Mojave has found great treasure easily and these are sites that I have hit many dozens of times.
One area is my prime experimentation site as it is an old main entrance to a park that was commissioned in the mid 20's.
It is surrounded by electric wires and some strong WiFi coming from a fire station built on this site in the 60's.
It has train tracks that run right through the middle about 6-8" because I have hit parts of them a couple of times.
Also some black dirt on top for a few inches but then red clay as you get deeper in some areas.
Add in tons of trash and way too much iron and you have the perfect storm of bad conditions for hunting.
Most hunters hunted here for decades and gave up on it declaring it hunted out.
I all the easy stuff is gone but because of the intense masking issues I always thought there was a bunch more here.
I was correct, in the last 4 seasons I have found silver dimes, nickels going back to V nics, Indian heads, wheats, silver jewelry, flat buttons and more mostly with the F70, a few with the Compadre.
I used the Vaq also but the iron made it not fun to hunt here even with a sniper concentric coil.
Before I had even a full hour with my new Mojave I walked into this entrance area an found a beat up silver merc.
First silver with the Mojave...didn't even take an hour - Friendly Metal Detecting Forums
Since then I found more treasure in my normal hunted sites most under difficult conditions.

My Mojave appears to be living at a deeper level than my older style, hot, 7" coil Compadre with the gain turned up internally.
It can hit the 3-4" range the Compadre can hit here but easily gets deeper by at least 2 if not 3" more consistently which is shocking to me.
The amount of masked older wheats I have found in pounded hunt sites with the Mojave is pretty amazing also.
For relic hunting I have hit decent sized iron horse tack as deep as 12".
The big thing is comparing the Vaq and the Mojave the new one is just way more easier, enjoyable and fun to use and pretty darn productive, too.
I believe it still likes iron a bit too much as some Tesoros do but there is usually ways you can use to tell with each one and this is easier...for me.
I talked to Alan Cannon at Tesoro once about the Mojave and he said it is not just a Compadre on steroids but a new, upgraded design.
It might seem work similarly but it ain't a Compadre.
He also told me there were some heated meetings about exactly how hot they were going to set them internally before they released this one.
Many wanted it higher than what they settled on because there would be even more depth but the side that one wanted them to be as quiet as possible in most of the areas of the country so it actually isn't maxed out on power.
Fine with me, I am getting deeper than the Compadre and better more reliable ID's than the Vaq gave me so I am happy.
Here, my Mojave is getting just as deep as anything I ever dug with the Vaq and in a few coins deeper.
That also shocked me, I have a theory that the Vaq could probably hit the same targets but I get a different frequency of tones with the Mojave that seems to be more pleasant to listen to so I can pick out more clues.
Out west in Kansas the Compadre worked magnificently...I could get to about 6-7" easily, found me a ton and I had few issues.
If where I live now was the same I never would have thought to think about getting a Mojave or getting rid of my beloved Vaq but things change and now I am all about making it easy on me in this crazy dirt I have to deal with.
The Vaq wasn't getting out much, the Mojave is getting way more swing time because it is fun again.
So I guess where you live might have a bearing on whether the Mojave is a better choice than a Compadre in my experience.
In great soil they all work well.
In problem dirt one model might have advantages and actually help some hunters out more than others.
I won't get rid of my Compadre, either...one day I will throw it in an Otter Box and waterproof it for river and lake hunting.
