The next time you get a signal you think is deep iron lift the coil while still swinging. See if the meter numbers go from negative to positive. Also try it over deep nonferrous targets and see how much the meter numbers change. By chance, I tried that yesterday and I saw deep iron numbers change from negative to positive as the coil was raised, while deep nonferrous numbers didn't change much. I have to try that again next time out. It might help prevent digging deep nails.

Maybe when the coil is lifted higher the iron object is no longer being detected and only the rust halo is giving a signal. Maybe when both the iron object and the rust halo are detected together the meter is very jumpy? I know if the soil is broken a little with my digger, the signal from deep iron will suddenly change and become a lot less jumpy. I think a silver coin is too pure to leave a halo trail as it sinks. I hope I can figure out what is going on.
Jabbo, there's a good bet that once that nail comes out that you still have lots of rust residue hanging out in that hole and the detector can resolve it better. Just my guess. I was using the 5" coil last weekend and liked how it id'd and had better target separation. The park I was in had the most iron i had ever seen and with that disc turned up to 90 it really ran well. It still falsed a lot but doing that circle trick i described i could id 90 or better percent of actual iron. Just to make sure you understand the disc on the C$ is for iron only not coins etc. I really think if you try those tips and give it a few more hours you'll get to like it.
Yukon, I made some notes about circling around iron, will try it in a few days. Waiting for the ground to thaw a little more, then back to the woods. I do a lot of searching in the woods and it's amazing how many deep nails I find. Why they are there, I'll never know. I rarely ever search parks any more for gold. Most coins in the woods are not deep at all, less than 6 inches. Will be using my 10" coil for wider coverage. Lots of 1700's King George pennies here in central Jersey, they're easy to detect down to 8 inches even with the 8 inch coil, maybe with the 5 incher too at that depth. In air the 10 inch coil gives a good signal on the tiny silver 3 cent piece at over 7 inches, usually they are not that deep in the ground. I like the C$ because it has just enough setting options, not too complicated for me to get it right in the field and it goes deep enough for me. I took a ladies thin gold bracelet and layed it out in an S shape on a cardboard box. All 3 coils detect it very well at 2.5 inches or better. In the field I can usually run it at Sens 10 and Threshold 0, soil here is quite mild. HH, Dave
Well I just moved to NC and the soil here us really sandy. I imagine the old coins will be really deep. I haven't found anything good yet because of all the trash I'm running in to. I think I will try a few fields here just because there won't be much trash and maybe I'll eyeball an arrowhead. I sure do miss detecting in Ohio
I envy your location. Good luck!
