Fisher F5 - Hints and Tips

Hi,

Just bought the F5 and very impressed with it's wet sand capability but I know I'm probably using the wrong settings.

Having searched the net I have found little in the way of advice, so please feel free to add your 2 pennies to this thread if you own an F5, so we can all get the most out of it.

I've found on wet sand ive been running it at All Metal 30 gain 0 threshold. But, it doesnt run silent. Using Desc mode at 24 I get quite alot of false signalling when I ramp up the gain to say 80.

Thanks in advance for your hints and tips.

It sounds like you need to ground balance the machine,

1)  turn the gain / sensitivity about a 1/3 of the way up now turn the ground balance to the right while pumping the coil up and down
     at a slowish pace, if you hear noise as you lower the coil to the ground then turn the ground knob the other way slowly
     until the noise goes away, now if it makes a noise as you raise the coil then turn it the other way, what you are looking for is
     just a slight noise as you lower the coil when you have done this then turn your gain up until the machine starts to chatter
     then back it off just a touch so it stops chattering the you are good to go, If you still have problems then give me a call
     on this thread then we will try something else, make sure your coil plug is tight and that the coil lead is wound like they say
     in the manual,  Good Luck
