walmart had a tasco digital microscope that uses the computer marked down to $15 from $60 so i thought i would give it a look, can never have enough tools
.
magnifies from 10x, 60x, and 120x. looks pretty nice and take the scope portion out of the holder to magnify whatever. has different lighting also.
there is a pic of the magnifier, of a piston freshly coated by swain tech, a closeup of the same piston, and the last pic is of the same piston with a few swipes with scotchbrite to remove some of the coating.
closeups are using 10x.
