Am i reading the F75 right?

[iliketodigit]

Attended my first organised dig this weekend and had the chance to have a full day with the F75.
Tried various settings and settled on DE mode, sensitivity at 50 to 60, discrimination at around 18. 3H tone, standard coil.
Other higher more sensitive settings were sounding off like a pinball machine on steroids.
The site had about 60 acres in two parts with the soil being very lively lots of non ferrous dross and bits of junk.etc.
The iron was masked out by a burp burp, burp burp type chatter noise and in and among there would be the higher what i class as the better more likely to be good targets.
They would be there on virtually every sweep but a closer check or re sweep over them would be less conclusive with a mixture of one way sounds or sounds that would have muffled reasonable sounds mixed in with chatter.
The readouts for these types off sounds would be all over the place changing from 20 right up to 80 and more on the same repeated sweeps.
To start with i did dig these signals but found them to be very frustrating and phantom like often having removed the soil the signal was very difficult to find it again i just did not want to think i was missing something good.
The ground was very much like super glue with all the recent rain and was really hard going it would cling to the spade your boots search coil etc so after a few hours i decided to dig only the better sounds.
Which is the right approach.
Is this the normal " talk " from the F75.
Any help would be much appreciated. Thanks.

I am also new and just got mine a week ago, And live in NC where the ground is red clay, try to get the best ground balance possible with the fast grab, and check out the saving history post here Bill ladd is using the F75 in some rocky terrain and it sounds good.I am learning this machine is Very sensitive and Takes a bit of time getting use to.Maybe he will chime in...Try lowering the sense even more this is a Hot little machine and Picks up every little thing..I am finding.

Thanks Liquid,
your right about the sensitivity and I'll definitely experiment, on the day in and among all the iffy signals it hit hard on even tiny non ferrous objects down to the size of air rifle pellets.
Small brass and copper buttons buttons the size of a modern day acrylic shirt button were pinging my ears off.
I think i was just taken aback at the depths that they were coming up from and trying to find them in the glue pot soil was really hard work.
I was also using a 30 inch long, 6 inch round blade digging spade.
For this machine in the plowed and rolled type field just isn't big enough !!!
A good solid digging spade with a bigger blade is my next purchase and also a "Sunrayprobe" for pinpointing both these will definitely save some time.
Thanks, Mart.

Saving History looks a gem and will have a look at F75.com. Thanks, Mart.

I went and hunted last night in the Dark sweeet lcd light..I got a high tone 80 Dug down and found 2 peices of rusted fence wire very rusted I taught it was a mask but could'nt find anything else put the wire on top of ground the machine did not pick it up..huh red clay anyone????, I had the small coil and in De mode, disc 21 notch 35 sense from 40 to 90, I taught I hit the mother load this was a local park near the kiddy play ground I dug at least 10" and was using the small coil..I just got to figure this Hot little machine out..I think its time for me to build a test garden.I live in NC lots of red clay..so I might try the manual GB to 3 pos..Just so many option..I;ll let you know how my first Relic hunt goes this weekend..I am taking the Big shovels..over 300 acres to hunt 4 old home places will use both coils..use to be a consession stand in one place..its my Dads place..cant wait..james
