Compadre and Amigo 2 observations and questions

[fowlercharles]

In reading some older post, and more recent post I am led to believe that there was a version of the Compadre that was the same as the Amigo 2, and then along came a "newer" version of the Compadre. The first Compadre would not have been low noise/high gain and the newer version would have been low noise/high gain. The discussion and pics awhile back on the Mod Forum brought out that there were older and newer boards in the Compadres,not alike, and that little, or no progress was made in an attempt to up the Sens.to a "slight chatter" and improve the depth on the "newer 5.75 compadres, and .allowing that the 7" Compadres were likely candidates for success in uping the Sens. If this is all true, what would be the possibility that you could "up" the Sens. on the Amigo 2.in the same manner? I may be off base with all this, but these things caused me to wonder what was what etc. Thanks, Charlie S Ms.

Charlie,
I went back and re-read that thread so I was fresh on what was said.

I have what appears to be a newer circuit board layout. Keith S. indicated that he got better depth and the ability to adjust the sensitivity more into the chattering range with the older circuits than the newer ones. Keith posts a lot of good information. He also seems to get better depth measurements across the board than I do. I did not see how many circuits of each type were involved in his observations. Keep in mind that small sample numbers can skew results significantly. My measurements are across exactly one Compadre.

I still have a little more adjustment on sensitivity, but it is almost maxed. I gained about an inch in air testing by adjusting the sensitivity up.

Set like this, the Compadre I have keeps up very well over most ground I've covered with the other detectors I have. If the ground gets ugly ... more mineralized ... it gets too chatty and doesn't really settled down. In that case I set it aside and pick up a different detector with ground balance and sensitivity adjustments that are on the front panel.

There is a trade off with running the sensitivity up on the Compadre. If the ground is consistent and the internal ground balance is set well for the ground you hunt, high sensitivity can be very good. If the ground is not consistent, high sensitivity can give a lot of falsing and that gets frustrating pretty quickly.

Can't speak to the Amigo.

Thanks tvr, you and Keith both put out some good info. I printed out most all of it for later reference too. I wasn't really thinking of messing with my Compadre, but was considering playing with the Sens on my Amigo. I havent even looked to see if the Amigo board is similar to my Compadre, but from what the situation appears to be with an older and a newer boards on the Compadres, my newer Compadre will probably not be anything like my Amigo 2. Lol, that is going to leave me with not the slightest idea of where to look for a Sens Pot on the Amigo 2. My dirt is supposed to be fairly mild to non mineralized. but I have learned in 40 years that that ain't allways so. I have not heard any of the other Miss. hands say much if anything about it in their areas, but I find Koalin patches from time to time and have several in my own yard. They can be a pain, and will have you digging to China. How about you tvr, are you near the Mississippi River in La. or Ms.? If so you may have some Mineralization same as I do. I think maybe up in the Delta there is some mineralization but nothing really bothersome.Just thought I would ask. As for tinkering with the Sens.Pots on any of my machines it is a thought but probably not a good idea, or worth the trouble. Maybe for a big increase in depth, but I like a quite machine. Thanks for the input, I appreciate it ! Charlie S Ms. PS I just realized the tvr would likely mean TV Repair. There is an abreviation on my PC weather map (tvr) that is for the area of Tallulah, La. and Vicksburg,Ms. and that is what brought on my mention of the mineralization Sorry for my confusion!
