On your 5th picture (Bottom Center). Divide it into 4 Quadrants. Top left Quadrant, bottom right of that quadrant I noted something of value at 9 feet deep. It is centered on that long white line between the river and hwy. Nothing of particular interest on the other 5 pictures. Just remember that I am a Novice so trust others to locate more.

First picture,blue is silver hits,yellow is gold hits,Red is junk and minerals hits......sense you learning to dowse,that why i showed the mineral's and junk hit's,go there and check it out,y-rod is best you can tell a true target,it will be pushing back to you.....mineral's will be pulling,this is one way to tell then apart.
ALL MINERALS FOR SURE, EXCEPT FOR THIS PIC. , HERE THERE IS AN IRON BOX CONTAINING GOLD & SILVER COINS... IF YOU ARE SERIOUS TREASURE HUNTER, GO FOR THIS ONE, IT IS REAL LIKE THE SUN IN DAYTIME. IT IS EASY TO CHECK IT OUT WITH METAL DETECTOR, BECAUSE IT IS SIZE IS 25cm x 20cm, LESS THAN ONE METER DEEP.
