[attachment 188300 SAM_0313.JPG] Went to area that has coke ash or fly ash pea gravel and iron could not get a steady threshold even with power down to seven in manual and auto did noise cancel.Does there need to be a threshold in order for it to detect coins?It seems that it would still finds coins even with the threshold cut out.I was surprised at what i found.I was using smart find and iron mode on and off.The threshold would cut out for three or four swing and come back on and off,i know there has to be a lot of iron there,really hard to hunt with my other machine.In order for me to keep a steady threshold ,i would have to move or swing as almost slow motion.I was using explorer xs and explorer 2.Coils 8 inch minelab and 10.5 minelab stock.Actuall in order to keep a steady threshold the coil would have to be 3 to 4 inches off ground.Stil found those coins and this area is pounded and hard to hunt.Is the minelab a noisy machine?Meaning it was hitting like iron hit half hit in some areas then it would go quite.Even if i was in a noisy area it would still sing if it found a coin.Wasn't getting a lot of depth surface to about 4 or 5 inches.Try turning power up a few times but didn't make it any better.Both machine acted about the same .Lot of question cant really compare it to my other machines because it is completely different.Still trying to figure it out going to take a while.i have found some junk deep in my yard but no deep coins.Though i have a few buried and it hit them hard those are 7 to 8 inches and couple deeper.Usure if i have setting correct,they are used machine i set them back to factory by holding power button till i herd reset noise.Iam use to running a xlt mxt idx ace 250 fisher id excell and ran a bounty hunter before have a lot of coils been hunting about 15 years.not use to pinpoint on minelab had to use the ace 250 with sniper coil to try and find the spot.Tried heal to toe walk out crossing lines tried walking in with toe of coil seemed a little better today then you seem to lose it and then figure it out again.Well thanks for any tips or help. Minelab 101 for me i have two books on them one is Andy sabisch mastering the explorer.
