Im new to this so if yall have suggestions im all ears. Yesterday I went hunting in miniralized ground reading 85 on the balance. I attempted to start my test garden and placed the first quarter at 6". The ground also is very rocky imagine mixing dirt and gravel. My 5x8 coil at max sensitivity in pro zero wouldn't see it. My standard coil did. I was about to hunt an old homestead so I really wanted the smaller coil. Im thinking I may need the bigger coil in this hot soil due to interference. Also had ghosting a couple times through the day.

Also my coil cover for 5x8 sags in the middle a couple millimeters where as my standard fits flush. Is that normal on 5x8 or should i contact Garrett?
 

I bet if you turn down the sens in that hot soil the atp will see it just fine.a smaller coil is seeing less hot soil at a givin moment and is a good way to overcome it.I live in a gold mining districk,black sand in every depression..gb 87-92 everywhere and 5x8 works it very well,just NEVER at max sens.

2nd..remove that coil cover,it is likely trapping material and/or moisture if not fitting right.either way,no bueno

good luck,let us know
 

Good deal ill try that next time thanks
 

Def TURN DOWN ur sens... I have VERY hot soil here in CT... need to turn sens back 2-3 bars... U may lose depth, but ur 0-5inch range will separate very well. Also, go: Pro mode, zero mode, notched to 35.,,, ur as good as done. Listen for the repeatable signals in between the trash... dig.
 

I think yall are correct. One just assumes higher sensitivity is better but I see what yall are saying about it in high mineralization. Im going to try that
 

I will be straight with ha ,, sometimes the "tests" aren't always reality .. I used to think that as true but when things ha been string I. The ground for years it will read different
