F5 air test

I have a old 1220x that does much better in the ground than it does in the air. It only shows about 5 inches in the air, but I have dug coins 6 inches or better in the ground. Bill in texasThe F5 gets impressive results in air tests if you set gain and threshold right and/or use the very deep All Metal Mode.
But the best thing about the F5 is that you get all the ground info on the display to keep the in-ground depth up to date. That is more important then posting air test numbers.

I was not impressed with the initial air tests when I first got the machine. But, in actual real life hunting I have been finding silver in places that I have used other very good detectors. None of the targets were out of range of the other detectors but for some reason the F5 picked them up. Maybe just luck but but I like the results so far.
Here is what I do. Set the GB with threshold at 0. Set the gain to where it gets unstable and then back it off just a tad. Then I turn the threshold up until the gain starts making the detector unstable then back it off a tad. That's it. There are many combinations of ways to set the gain and threshold. It's up to you. Just make sure you GB the machine correctly.
If in a park or somewhere that has a ton of can slaw you might want to set the threshold at 0 or - to make the detector less sensitive to the aluminum.
