I never thought that I could be so confused to start with with my new f75 detector.
I suppose it does what it suppose to do. Just not simple as I was led to believe.
I am going to have to learn this machine since it is not turn on and go one.
This is not my first detector. For last two years I've use only Garrett Infinium ls and it took me few months to mastermind, but now I am very comfortable with. On Infinium ls I learned how not to dig foil, pull tabs,bobby pins and most bottle tops and I expected F75 to mask them for me. This is not a case at least for now.
I bought F75 for specific reason to avoid bottle tops and pull tabs in the grass/lawn area where I want to use it and for its lightweight construction.
It will be primary use in trashy areas where bottle tops easily outnumber any other type of junk there, old and new.
I do not mind digging crap as a learning curve but on the beach I am not a cleaner and try to recover only what I come there for and live the rest undisturbed. I hope you understand my point.
After removing most of metal object on my test patch I used those holes to bury all modern Australian coins we have just for the test propose. Modern Australian coins composition: 5c - 50c 75% Copper, 25% Nickel , $1 & $2 Aluminium Bronze: 92% Copper, 6% Aluminium, 2% Nickel. Conductivity of US coins is different to Australian coins.
I used discrimination in dE and bc and all metal mode both in factory settings just to get a feel of it.
It can find them easily and deep but my point is target ID, it puzzle me a bit, bottle screw top give me similar number then 50c and all other coins are all over place.Also ID very from left to right and right to left swing.
I can understand why some people would junk F75 after short time of use , but in the long run is the user and his knowledge of machine that counts.
I cannot wrap my head around discrimination and notch at this moment
Also I don't know how to utilize this machine properly either, but pinpointing is so easy.
In Bc mode first thing I dug on the dissent signal were bottle cup x4 before number of pull tabs. Shouldn't this mode mask them somehow?
I know that bottle tops are an occupational hazard when detecting .
Q:
1. Why I get different ID numbers on the same target in dE/bc Mode and all metal mode?
2. Why is a different ID number on the target when swinging from L>R and from R<L ?
3. What is learning curve on this machine 40,100 hours ?
4. What is best setting or mode to use for prospecting JE or all metal and how to best set it?
5. How to set F75 to avoid bottle tops and pull tabs ?
6. What audio responses or tone# setting give a good indication of what to dig or what to ignore ?
Thanks Michael

- lemme know when you figure it out! The tail end of the DD will sound off as iron on steel BC's but because the 11" DD is so long it can also mean you've moved to an iron target in front of the bottle cap. If there are BC's then you're normally in a park or yard and that means you just have to dig them. If you don't, you'll miss something good.
