Default Discrimination Pattern

[gibsondan]

I uploaded a diagram of the E-trac's default discrimination pattern. Anybody have any ideas about why sections A and B are discriminated out? Eisenhower clad dollars fall in section B. I changed my discrimination pattern to accept them. I suspect the default pattern may be based on Australian or European targets. Any one have a successful pattern for U.S. coinshooting? Thanks.

Try these patterns. You have to download them first and then open them with your Etrac software.HH EddieB

I believe the Andy_S_Coin_Hunting_Pattern looks like a better discrimination pattern than the default one. The All_around1.mode discrimination makes more sense to me for U.S. coinshooting. I saved both files. Thanks, Eddie.

Not exactly sure if this is correct, but i believe the reason for section B disced out is from the iron falsing wrap around effect. it happens when iron is completely discriminated, yet has such a strong signal, it can "wrap around" and hit in this area. I too opened this area up. Feel free to correct me if i'm wrong, but another way to reduce falsing AND still get the depth is to use manual sensitivity as i believe it is deeper than auto. Exampleair test only) I measured the detection depth of a large '78 dollar coin @ 10 1/2 inches with 16 manual. switched over to 16 auto and detection depth was reduced to 9 inches.
