NASA-Tom question.

In paragraph three of compilation #1, you were hunting in PF mode. Is this a preferred mode when you can't run in JE mode?

Yes. And on that note, the 'pf' mode and 'de' mode are just about absolutely identical in real-world performance .... in most locations.

The reason I ask it that there is a measurable difference in depth and target response HERE between PF and DE modes, at least if you can believe my test garden results. In my woods sites I see no real difference, but the targets are relatively shallow in "most" of my woods sites. In the huge fields that I hunt, you can see a marked difference in depth between PF and DE.(A bit crisper audio response as well) My Dirt GB's between 65 and 70 (depending on soil moisture), and usually there are NO FE304 bars, and if there are any at all, its only one bar. interesting......... Streak!
(I havent tried either in freshly plowed soils, as I tend to avoid them)

MINERALIZED lumps/clumps will do just exactly this! ('pf' vs. 'de').
