This area has been hunted for years and is full of iron,but I thought I would give it a try today with the F75 and it did not let me down. When I got there I noticed dug holes everywhere and they were recent and then I saw drag marks from a shovel then I new who had been there. When I got home today I gave him a call and told him what I had dug, 19 flat buttons 1 bell button 1 ball button and 1 indian head penny all he could say was :Man that new machine must be good: And of course I said Amen the F75 is one digging machine.
