4. of discrimination the 1236 X2 rejects some targets and continues to respond to others You have now determined the discrimination points for the rejected objects For example the small nail discrimination point may be at 3 and the pull tab discrimination point at 7 8 Some objects such as shallow bottle caps bent pull tabs or trash less than 2 inches from the coil may be difficult to reject The 1236 X2 will instead respond with a strong broken signal which will usually disappearif the search coil is raised slightly whereas the strong signal of a good target will usually get weaker when the search coil is raised FE 1236x2 manual 8704810 indd 12 PINPOINTING IN MOTION SEARCH MODE Pinpointing in the Search Mode will take a little practice but you may find that for most targets it s even quicker than the No Motion Pinpointing Mode Simply use the same procedure as in steps 2 through 5 on p 14 The only difference will be that when you stop the coil over the target you will lose the audio signal You must keep the coil moving at least slightly to determine the location of the strongest signal before you stop it 1 For very strong signals you may improve your motion mode pinpointing accuracy by adding one or more of the following steps a Lift the coil until the signal isjust barely heard b Reduce the sensitivity level c Increase the discrimination level d Rest the coil on the ground and move it back and forth very s

8. NT button pushed the 1236 X2 detects all metals so you may pinpoint a piece of nearby junk instead of a good target For this reason you should always recheck your target area after recovering any target to make sure that you haven t missed anything You may also receive false pinpointing signals in highly mineralized soil In this case it is important to keep the coil parallel to the ground and at leastan inch above it mmm Tak 6 9 06 10 08 58 AM FALSE SIGNALS A false signal occurs when something that shouldn t sounds like a good target Your 1236 X2 does an excellent job of ignoring junk but it s so sensitive to good targets that it can be fooled by bad targets with similar electrical characteristics Large pieces of trash for example or even some kinds of bottle caps and pull tabs can fool you Small pieces of trash less than 2 inches from the search coil will also sound good occasionally So what do you do about false signals Well 90 percent of them will sound suspicious to you after you ve had some experience and you ll just ignore them They may be very faint or very abrupt with static Often when you go back over the same spot a false signal will simply disappear Other false signals may be very loud and sharp but most of these will disappear if the coil is soeeded up orraised slightly Some shallow large or irregular pieces of junk however will fool the 1236 X2 no matter what you do Here s some other so
