Great digging,by the looks of all those wheats I bet there is a lot more silver out there to find. Did you find the old swimming hole? Maybe you can locate where they used to practice parachuting,bet they would drop all manner of items doing that. I had a Garrett 550 as well found a ton of coins with it,gave it to one of my twins for christmas,hes caught the bug as well,good dependable machine,get a rain cover for that thing and get back out there,when its dumping rain you can hunt around the trees,HH...Shoot
