If you have G&H shells you can buy removable floats for both the reg and mag size.
A do it yourself float can be made from rigid polystyrene foam insulation. Trace the decoy outline on the foam, cut it out and glue it with waterproof caulking. Remember the put a small hole in the foam to run the decoy line it and glue the line to the foam before you glue the foam to the plastic shell.
