unarchiving BIN file using archive utility

I have recently resieved some software in the form of a ' .bin ' file. The 'Archive Utility' says it cant 'Unarchive' the .bin file as it is unsupported, even though it is a Mac version of software ( Sandisk RescuePro Deluxe 4 - came with High Quality CF Card ). Some help would be greatly appreciated. cheers :-))
