You may get different opinions about this.
But I think that the Silver uMax works well
in iron if it is ground balanced properly.
It will pop and spit at the iron, but ignores
small stuff.
I think most people lower the sensitivity
a lot. That makes it quieter. I prefer to
keep the sense as high as I can and just
tolerate the pops and spits.
I think the Compadre works better in iron.
In my opinion the Compadre is killer in
heavy trash.
How can this be? you ask<><>
You will have trouble with getting depth
in heavy trash. The deeper your signal,
the more junk picked up at one time...
That's making the problem worse.
The Compadre doesn't have that much
depth. But it can isolate targets real well
and ends up getting just as much depth
in heavy trash as the deeper machines.
In other words it's hard to beat in heavy
trash.
It surface hunts real well. It's easy to tell
depth with it.
A better machine in iron is the Eldorado.
I like my Euro Sabre for handling iron.
It's just like the Eldorado, but has an
Iron ID feature.
I found a 0.10 gram ear ring made of 14k
gold jewelry that was right over a 3/8" steel
nut. It was also close to a steel reinforced
concrete slab and under a chain link fence.
A few days later, I found a piece of 10k gold
with my Euro and it just weighed 0.03 grams.
It was under iron playground equipment.
It's very sensitive. Today I recovered a strait
pin with it.
I was in a tot lot and digging everything without
even checking it.
Not many machines will even air test a strait
pin, much less recover one.
That's my 3 cents worth,
