F4 question from bxlarry

[bxlarry]

I live in south east Florida and like to MD the ocean beaches. I was just told by Fisher
that it is not necessary to ground balance the unit on dry sand do to the high mineral content.
Does this make sense to anyone?

Sounds more like miscommunication between the two involved parties to me!

Not at all

The majority of machines will work fine in the dry sand without ground balancing.It's the damp/wet sand that causes false signals and chatter on machines without a salt elimination mode,or ones not ground balanced to the conditions. You can use the machine on the damp sand,as long as you decrease the sensitivity and poss increase the discrimination. The Fisher F4 ground balance control only affects the "autotune" mode and the pinpoint mode,it does not carry over into the discrimination mode. This comes from Dave J.(Woof!) one of the designers of the F4. Thanks.
