Is there any better (generally available) material to wrap around the  magnetic compass to shield it from interference, that's better than  MuMetal?  Thanks Skip

		  Neil,



Just do a Google search on "mu metal" and you will find a lot of sources.  Not sure any will be cheep as Nickel isn't a cheep metal.

		  Neil,



Just checked McMaster-Carr.  They have it in foil form.  Thickness 0.002, 0.004, 0.006 & 0.010 (inch), with or without adhesive backing, widths 4 in or 15 in.  Sold by the foot.  Prices range from $0.97/in to $6.92/in depending on thickness, width & backing.
