I know there's the huge coil, also-but I just got back detecting with my Freedom III with the 71/4" coil and found not pennies BUT QUARTERS that have been passed over by me with the standard coils. Now these aren't new quarters that may have been recently dropped, but patina covered quarters that have been there months. I feel certain my Ace would have picked them up with a 7" coil as this groundhog-type coil seems to be perfect for coins. If Mr. Garrett himself believes that MOST th'ers are coin shooters, why not give them a coin coil? I need to cover ground and the sniper coil would take forever to cover a football field.
