Is there a 1220x schematic out there ?
thanks

Don't have that one but I have the two around it !

[jessadr]

thanks I was wondering what was in that black block

I think its the same as the 1260x just on the older hook stick shaft design

Some photos of the 1260x here http://www.geotech1.com/forums/attac...5&d=1326302606

If so the 1260x schematics are available online.

I had 89 views on the forum "treasure net" not a single reply. This is the best site by far . I guess there is a elite club on some sites. I ain't a member. One of my best books on detectors is the one off this site.

The 1220 is a repackaged 1260. The "black box" is the "front end" which is an active bucker system we thought at the time was IP worth protecting. No other models used that system.

I own both the 1260x and 1265x


The 1260x (aka 1220x) is a great machine and handles iron much better than the 1265x


The faint zip sounds on the 1260x are very consistent on deep non ferrous targets if it sounds dig it out. On the 1265x deep iron sounds just the same as a good target unless you turn the sensitivity down. When you do the performance is the same between them but deep targets are louder on the 1265x


1220x is well worth fixing up. In the field results were better than my IDX or Bandido.

I get a solid 10" on a UK silver 3 pence which is a tiny thin coin. There's another inch that's an iffy may or may not dig and it doesn't loose much in my soil. Best of all its not much less when the coins on its edge and the discrimination is cranked up.


Neither handle coke well and both seem to loose depth in waterlogged ground.

I wonder if there is an adjustment setup info out there some where ? It has a bunch of adjustable pots on the board. Or I wonder if a few of them can be moved to pots on the box for adjustments like the 1260x

I set mine up. But can't remember the POT locations.


Sensitivity crank it up until it starts to chatter the back it off until it just stops


Unusual is there are two pots for ground balance. One for slow sweep the other for fast.
Set with the discrimination on 0 and sensitivity on max. Graphite 2" above the coil waved slow adjust for least sound then speed up and adjust the other POT the same

Discrimination is set with a large copper coin. Disc on 10 wave coin 2" above the coil and adjust until its just fully rejected.


Sorry I can't remember the POT locations. I couldn't find the information online. I had to email a repair shop.

wow maybe someone will find the setup paper on it Is the 1260 the same board with more controls ?
