DFX user needs help

[Bossgobbler23]

I am running a modified "Deep Seeking Missle Program" Pre-Amp 4, AC 75, DC 40, Sweep Speed 1, Recovery 10, DC Phase On. When I pinpoint a coin, the depth is showing deeper than it really is although I am running with the stock coil. Is it because I'm running hot or does it have something to do with the DC?
Thanks

? ? ? ? I've been learning my DFX for nearly 2 months now. So i'm by no meens an expert.
But very close.? ?NOT!? ?I'm thinking it is how low your running your DC sensitivity. If your running your AC at 75 and not having any false signls and so on. Then i would turn the DC up to at least 50. I always run my DC above 50. It's the AC that i have to go up or down on depending on interference or falsing and such. Along with PRE Amp. Which i see yours at 4. I've rarely been able to run mine at 4, usualy 3 being the highest. Also while pin pointing, depth will read more. After pin point put pad to the side and squeeze trigger and pass over till directly above it will give the most accurate depth reading. Which on mine always shows an inch to one and a half inch less than while pin pointing. ? ? ? ? HH
