Put in 4 hours At the fairgrounds this weekend , hunted a spot I had hit with both coils 6 and stock coil .
So I tried the silver and relic pattern and separation mode high trash and ferrous coin combine . All these coins I had missed was using the 6 inch coil in a area about 30 by 30 the reason I had missed them is because of the sound they all sounded like falses but they were repeating signals MOST of the time there was so much iron nothing would lock on .
I had to physically stop the coil in mid wiggle to get a id but if the coil moved that little bit it would not give me a id . If I over shot the target it would always be iron basically you had to hunt by sound id was to hard to get .
So I would get that high tone mixed with iron both ways but you could hear the high tone sometimes all the time and sometimes it would come and go when I turned 90 degrees it would still be there or just gone . When I mean it was still there it was iron and a high tone sometimes .
All the coins were at 4 inches deep I would check out all falses some never repeated or were extremely hard to get to high tone again a real false those I would ignore the ones that were interesting were the ones that would repeat not all the time kind of like a false but it would high tone every pass or every other pass but stayed in the same place on the ground .
Now here' a little tip I found out about pinpointing in a pile of iron I always run pinpoint sizing when you get that spot where the high tone is coming from you can't pinpoint it because of all the adjacent nails so I would go to pinpoint sizing find my spot hold the coil right over that spot 2 inches off the ground this well detune pinpoint sizing then I
would I lower my coil to a inch and the targets would sound off again but not as loud some of the pinpoints I did have up to 4 different targets under the 6 inch coil at one time .
I don't no why I had missed these target's but it might have to do with conditions it is BONE DRY out there and maybe the iron is not as lively as when the ground is moist.
From now on every false well get 2 or 3 sweeps to make sure it is a false and not a coin with iron , I only dug 6 nails these were probably falses from 2 different iron objects at the same time making a 90 degree turn and had it false the other way . But if you get a iron coin mixed audio several times out of 6 passes check it out because when it's in iron sometimes it won't repeat on every swing . sube
