Hi Blowfly,
I don't know any thing about salt water beaches. Arkie Land is too far from the ocean.
Salt is a metal that is hard for any VLF type detector to handle.
I can tell you that the Compadre handles harsh ground conditions better than the Silver.
If you like to cherry pick, the Silver is the machine. With the discrimination turned all
the way down, it discriminates small iron with out loosing any depth. Then it gives nice
signals on any potential target. Small gold will be picked up with the discrimination all
the way down. As you turn it up, the gold starts going away, starting with the smallest.
The Compadre has a lower discrimination range. It will go lower than small gold. It is not
as deep but but it is more thorough. It can handle trashy sites and harsh conditions
better.
The Compadre has no sensitivity control. I don't know how it works, but it detunes it self,
there by adapting to almost any existing condition.
Both these detectors are fast and fun. Don't go behind an experienced detectorist with
one of these machines and expect to match his finds.
I like my machines with manual ground balance. But the truth is that my Compadre and
my Silver find more gold jewelry. They are quicker and, frankly, more fun.
But, on the other hand, when I need the extra depth in conditions that are rough, my
Euro and Vaquero fill that void. They are also good at finding gold jewelry.
All four of my Tesoro's are good all around machines.
I think you will need a land machine and a salt water PI machine to match your needs.
But you can not go wrong with the Silver or the Compadre. I can't decide between them,
so I have both.
HH,
