I was thinking just yesterday ... that while I do not have a Compadre... I was wondering if it wouldn't do the same thing that my Omega-8000 does with more simplicity and cheaper.
... The Compadre I have has a 9x8 coil hard wired in. I've tweeked the sensitivity pot up to where is crackles most of the time. With the coil very close to teh ground it quiets a bit but still pops and cracks. When it hits a target it hits solid and quiets down then allows very repeatable re-sweeps of the target. Even with the the bigger coil and tweeked sensitivity, the best it will do on a quarter in mild ground is around 8 inches ... maybe 9 on a very good day with a very iffy signal with the coil scraping the ground. As ground mineralization increases, depth starts to go away, although the Compadre does not seem to be nearly as sensitive to being spot on with ground balance as the Tejon likes to be to maximize the detector's depth.
It is very sensitive to small stuff. Unlike the Cibola and Tejon, it is deeper on quarters than it is on nickles. Dimes are about the same depth as nickles with the Compadre. The Tejon and Cibola ... and probably the Vaquero, but I haven't tried one ... are deeper on nickles than quarters.
Compadre discriminates exceptionally cleanly. It also masks good targets in the vicinity of discriminated out targets; but masking depends on relative orientation, relative depth and size.
I am thinking the 7 inch coil is the best overall compromise for most of my hunting with this little charmer, but can see why they are now delivered with the 5.75 inch coil; to ensure it produces well in virtually all conditions.
It is no depth demon, but it is respectable, particularly considering it's price.
It is so light that I grabbed it to go out and get some sun when under the weather with the flu and not wanting to do anything except get some sun. That flu ridden hunt with the Compadre got me a very nice, very unexpected Indian Head penny.
Julian, you should try one for kicks!
