Need some F70 answers.

[davkeene]

Yesterday I burried the following in clean soil at 61/2" to 71/2" and marked them with wooden stakes: 1948 wheatback, 1945P
War nickel, 1964 Roosevelt dime and a 1934 quarter. All coins that I have dug up in the past. Today I tested these four coins
with my old Fisher CZ70 Pro. It read each coin and pin pointed correctly. I then tried my new F70. It picked up the quarter only
and would not pinpoint any of them. I used programs from the Forum that were highly recommended. De Speed with 0 disc, 0 thresh.,
60 Sens and 3 tones. I also tried the SL Speed with similar settings and no luck. What am I doing wrong? I tested the F70 to
Fishers recommendations to see if my unit was the updated model and it is. Thank you in advance for any help you may suggest.
Dave.

Did you ground balance first? That seems to make a huge difference in depth, even in mild soil.
