well today I went out for the first time to hunt my moms 60 acres. I found with the help of my fiance two 8 in railroad ties 1 hourse shoe 10-15 nails and a lot of soda cans not bad finding for the first time i dont think. what i am not happy about is no mater what reading i got it was a nail i had a lot of readings in the high 80's to 100 some in the 40's. it seems the ground is very heavy with iron minerals and when i pin point it never seems to be where the pin pointer is saying. i dig 4 inches and then it is saying 4 more or 6 more. i am still a noob and i really cant complain to much but i tjust did not seem my f4 worked how im told it should i have been reading the manual over and over for 4 days and playing with in in the yard before even going for a hunt. if any one has any advise or maybe what to try please let me know. i will post pics 2moro HH
