first off,I aint hear to say negitve things about you or your hunting pratices.Silver can be and is very elusive and it never just jumps out. I dont know how long you have been detecting or if this is your first detector.There was a time when I felt the same thing, it was a different detector but everyone else was seemed to be pulling silver except me ...I hunted what I felt were ""good silver'' spots,but still no silver.Finding silver does take "work'' as was mentioned.While I aint real well versed with the exterra I can say if you have a detecor that is capable of finding silver you will have to work at it.Silver coins are gonna be (in most cases) the deepest coins in the park,so you will have be working at a slowere pace and listening for alot fainter signals...deep coins will not sound the same as shallow coins,so if you are expecting to hear the same sound as a shallow coin with the only difference being the depth indicator saying its a deep one then you wont find silver ...You will need to put in major time at that site and clear out some shallow stuff untill you consistantly cant get into the strata of the earlier losses,(silver and wheats) if you start consistantly pulling the sixties stuff you are getting close ....keep at it....It took me quite a while before I found a silver but by the time i did I had learned Alot..stay with it and you will be rewarded,but its a touch unrealistic to ""expect silver"".To be honest when I really feel I should find silver I never do,you'll need to be paitent and relaxed then you will go out and one day just get into the ''zone'' and you be finding silver,also you have to remember although a place seems like it hasnt been hunted,It probally was ....Silver reached 50.00 an ounce in the eighties and people were hunting with metal detectors everywhere..If it was a true ""virgin site''the the cfoins you were finding at that depth would of at the very least produced a wheatie or two...... Stay with it bro and dont get discouraged....Too Many people out there have a detector just sitting in the closet because they didnt find old coins right out the gate ...........take care
