The cache is NOT at the posted coordinates.
To obtain the final coordinates for this cache, solve for N 41° 1A.BCD W 81° 1E.FGH where A-H are whole number weights between 1-9.
To attain perfect balance, each horizontal rod must have equal torque on both sides of its pivot point. The torque of each shape is its weight times its horizontal distance from the pivot point. The total weight of any balanced rod equals the sum of the shapes attached to it. To keep it simple, we will pretend the rods and descending wires themselves add no additional weight.
Congratulations to Muddy Dawgs on the FTF!
