) Dont know the age of knob but I think this field holds older stuff because I found a large tombac button (forgot to photo!). This site might date back 100 years earlier. The farmer doesnt waste time. He's now cutting the bean fields and planting wheat right behind the pickers. Hope all the farmers dont do this or we wont have much to hunt this year. 
Took my wife out for 1st time in 20 years and I set the deus up for her to use on a newly cut soybean field. She found 2 indian head pennies and various relics. She was pretty happy with the machine. Not bad for her 1st day out with it and her 1st trip in 2 decades.
