Lizz its a great, been using it for a couple of year before I got the F75 LTD, It will go real deep, unbelivable depth with the 10.5 coil even down to the 5" coil. Ok if she hunting relic, or foundations, ALL/METALS you need a good G.B. after that set the SEN up to about or till you get back round noise, This is important till her not to be afraid to lower the SEN to stabilize the machine, the 1270 still goes real deep with very low SEN setting, I've dropped it 3 or 4 and still got fantastic depth ,then set the iron to 9 or 10 and check your A/M target VIA toggle switch(push forward).
If your coinshooting make sure the GB is off, turn it on now you can go: DISC as first search and Iron as your swap, I use number 5 on DISC or ADJ it with a nickel loss the nickel then bring it back in, remember that setting for the future "NO NICKELS NO GOLD" set the iron up there again and check your DISC hits on the iron DISC, no sound you know it was small iron, won't get large out. Or you can swap the other way around Seach Iron first and check with DISC, I find this way better because thats where the SEE THRU IRON TRASH works Good sound in Iron and good sound in DISC real good chance its a winner, increased my silver and old coins findings a hell of a lot. Remember Unstable lower the SEN, don't be afraid to lower it.
Also if you cant make it run stable and the noise is eractic in the air , everywhere no matter what you try call Felix at Fisher sent mine back twice for that,once it was a Gound Bal Pot was bad, and the other was the coil, you might want to try a nother coil if that happens again cause my 8
' went bad put on the 5" and worked great.
