Anyway back to the hunt here are the settings I used pattern 1 was total open screen ferrous coin combine fe line at 26 pattern 2 was open screen ferrous coin combine fe line at 26 with disc set at 31 to 35 my user button was high trash open screen conduct 4 tone pattern 2 for user screen was open screen with 31 to 35 disc out .
Now I would run in high trash open screen hit a signal and switch to pattern 2 high trash with 31 to 35 disc out when I was in pattern 2 sometimes the cursor would lock on the target better compared to pattern 1 such as the 1920 penny I found which happens to be the only coin I would not of dug in my combine modes this had a lot of iron with it mostly nails.
After finding the object I would switch to pattern 1 ferrous coin combine if I got a high tone with grunts I would go to pattern 2 ferrous coin with the 31 to 35 line disc out this made it a lot easier to hear just the high tone okay .Sounds like a lot of switching but can be done in about 15 seconds or less .
Getting back to ferrous coin combine it's hard to fool this mode real hard the only way you can mess it up is by not getting directly on the target when wiggling I think if you dig iron in this mode you are really stretching for a good signal it is that good trust me .Very hard to fool period .
I think if I had the 6 inch coil I would of got that 1920 penny because there was just to much iron under the stock coil also the two pieces of jewelry were not very good in ferrous coin combine they were ragged cursors and sounded fuzzy I think it has to do with the shape of the item ferrous coin really likes round things .
High trash sees all the conductive targets and iron that is conductive where as ferrous coin combine is very selective at what it gives a high tone to , but you will miss targets with ferrous coin that are with iron because you have to be dead on that high tone to give a high tone and it's hard in iron Lot's of iron to hit that exact spot .Now high trash really doesn't care because it doesn't have to be dead on like ferrous coin combine so it will see more targets than ferrous coin combine which is great because you can at least know where the target is because it alerted you to it .
I think I'm going to name combine mode as the confirmer it's that good just got to hear what it's doing when in iron especially with all the grunts and falsing going on that little bit of disc really helps clear a lot of the signals up. I also dug about 20 more nails just to make sure that ferrous coin combine was right and it was sube
