Sample sensitivity air testing on the F75Ltd

[WV62]

Just wanted to see if there was any kind of steps in the sensitivity as for distance from the coil on a target. Didn't have near the distance to work with that I expected 1" was it 9" to 10".

I just picked the boost processor to work with and was using the 11" DD coil, my target was a silver quarter. I started sensitivity set at 1 then jumped to 29 and then to 30, after that I went up in counts of 10. I was thinking I may hit a distance jump in the 80's but was way wrong.
Sensitivity 1= 9"
Sensitivity 29= 9"
Sensitivity 30 and 40 were still 9"
Sensitivity 50 hit 10" and stayed 10" up through 99.

Then I went back between 41 and 49 doing a count of one and the 9" to 10" jump happened at 48 sensitivity.

Not sure this will help anybody, but I thought it is information and somebody may get some benefit from it.

What it kind of told me was that for coin hunting I don't really need to push the sensitivity to hard to get the good deep coins. So for my next hunt I will be running the sensitivity at 60 the factory reset number and if there is some noise I will back down to 50. Normally I try to run sensitivity at 85 or higher when actually hunting.

Nothing magic here just info.

Check with Tom Dankowski he has done some serious testing with the F75's. I always ran my pretty hot,better see through in iron.
Example. I had this spot at an old ghost town site. One area was loaded with iron, machine gun iron. I turned sen. down thinking this would help. Only pulled one button. Then I remember Tom or Keith say run it hot in iron so I cranked it up. Pulled 2 IH's and a cut1/2 which was pretty tiny . Give it a try sometime. Be ready for brain fatigue lol.

p.s. I was running in monotone disc at 6 .
