1. We’ve already said it but it bears repeating: TAKE 
YOUR TIME AND OVERLAP YOUR SWEEPS. 
2. Keep your trash rejection level set low. You’ll dig 
more trash but you’ll find more good targets, too. 
If you continually run at the pull tab discrimination 
level you’ll find  coins  and  silver  rings but  very  few 
gold rings for example. 
3.  Use  good  headphones.  You  won’t  miss  faint 
targets,  you  won’t  attract  unwanted  attention 
and you won’t bother others. And you’ll get longer 
battery life. 
4.  Practice  pinpointing.  There’s  nothing  sacred 
about the methods described in this manual. Many 
1212-X users have developed their own pinpointing 
methods. 
5.  Always  bury  a  coin  when  working  in  unfamiliar 
territory  and  check  it  at  different  Trash  Rejection 
levels. There is some sensitivity loss at higher levels of 
discrimination. The greater the ground mineralization, 
the higher the sensitivity loss. For example, you may 
be able to detect a penny 6 inches deep at zero 
discrimination, but no deeper than 4 inches at the pull 
tab discrimination point (see Figure 7). Also, ground 
mineralization  can  reduce  a  detector’s  ability  to 
discriminate  accurately.  In  highly  mineralized  soil, 
some trash targets may not be rejected. 
6. When in doubt about  the possible  identity of a 
target, dig it up. 
7. The 1212-X is an easy detector to use but if you’re 
having  trouble  with  any  aspect  of  its  operation 
(pinpointing, searching false sig- nals, etc.) go back 
and reread the part of this manual relating to your 
problem.
