Thinking of getting the F70 because it seems simpler than the F 75. Money is not a problem but ease of use is important to me. I've been told by some that the F70 is not a very good detector(much reduced detecting power) and that there is an oversupply of them? Is there any truth to this? Also in practical use what would i miss if I bought the F 70. Got rid of the Whites DFX because it wore out my arm............so now I'm looking at Fisher. Help me to make a good choice, need your opinions and advice on these two units. Which way would you go.??? Thanks for your replies!!
