Ground balancing 1270

[88junior]

No auto ground balance but it's set up to use in most soils that have light to medium ground mineralization. It goes pretty deep and my ground minerals are pretty bad! I never use the all metal feature it drives me nuts if it had multi tones instead of single tone I would use it then. Also Hallvard you may have some hot rocks in your soil they will drive you nuts in all metal mode.

Guess what guys!!

I was so fed up with the detector a while here, so I did began to make google-search for groundbalancing the 1270 in disc. Suddenly I found one comment in this forum. It said it was a potensiometer beside there the cable is connected inside. I opened it and took my detector in the woods...searched there I knew it would be a lot of beeps because the minerals. I adjusted the meter very careful, and suddenly it was just "popping" and "snapping" over the hotrocks instead of giving me clean beeps...and afterwards it was like a dream to detect with it. I tried out some tests in the same soil, and coins in 9" to 10" depth was no problem. I think the detector has been opened before, because I observed something I think is a possible attempt to modificate the detector. I guess the meter was in a wrong setting...

Yeah!!!

I had a 1270 for 4 or 5 years and it was always noisy. I only had the 5" and 10.5 in coils because I had bought it as a demo without the 8 ". The preset disc ground bal was too positive for my area, so after a few years I got tired of it and opened it up and set the ground balance pot for my soil , with the disc knob in disc 0, . It was the pot right in the middle of the top of the circuit board if I remember right. I think it had a small blue phillips screw setting adjuster. I almost went as far as drilling a small hole in the top case, so i could get to it whenever I wanted to, but I knew the pot would not take a lot of tweaking, so I just left it like I had set it Also if anyone want to try this , make sure you know where the initial factory setting is , there are small index marks on the pot, it is very sensitive so make very small moves, and if you mess it up, put it back where the factory setting was. . Anyway I set it to nuetral, then I set it just a little positive. I was in my yard , and I took a few sample swings and got a good deep signal, it was a dime at 10 ", the deepest dime I ever got with it. After that it seemed to run quieter and maybe perform better,. If I got another 1270, thats the first thing I would do.

Nice information Ladigger My 1270 works as a dream now. Last Night I found 2coins together almost 12" down in the soil. This was at a little old park with a lot of trash. The coins was from the 1980's...think the soil have been "moved around" a lot, because after 15 more meters i found a Dansish skilling from 1771 at about 5". I really nice finding. The machine disc very well, and I am about to know the signals much better now Love the machine and its depth!!! Im going to post some pictures of my findings after about 25-30hours searching at the forum now...
