Coilteck AI coil response
Posted by: Digger70pa

I tried my 14" AI coil yesterday. I had trouble with it. Everything sounded the same. All targets had a double response. Is that normal? Any help is appreciated.

NO!!! It should run like your other coils except for the fact it pinpoints in the centre of the left side of the coil. If all tones are the same, check the Signal Peak setting as it may be too low, Factory Preset is 16. If the Signal Peak setting is ok, you have a duff coil. Not sure what you mean by Double Response. Most signals are two toned except the very deep ones, that is a high/low or low/high tone. A deep is more mono. Targets near the surface can give two responses.

It allmost was like four signals on one target that I went over. Very confusing to say the least.

I hope I didn't get a bad coil. It didn't respond like the factory DD.

Was the target ferrous or non-ferrous. As you probably know a length of elongated iron can give two or three signals.

Also check you switches, make sure the Coil/Rx switch is at DD, it is easily knocked to Mono or Cancel in transportation.

If you know someone else with a GPX ask them to try the coil, if they get the same results it is a faulty coil.

Ok thanks I'll try those suggestions. I did make sure the machine was set to normal timing general search DD coil & tracking off.

I tried to use it yesterday. It's very different from any other coil I use. The responses are hard to comprehend.

When you get that multi signal, use just the left side of your coil over the target, and as usual circle around your target for discrimination. Pinpointing with this coil is my biggest challenge, but its been very productive around power lines.

Yes I'm having problems pinpointing with it also. Thanks for the info
