Ok, I have just been in contact with saxon and they have told me that the specs Page has wrong details for these binoculars, they have assured me that they are indeed fully multi coated and Bak 4 prisms. The description Page is right but the specs Page is wrong.
Thanks for pointing this out to me. I have no idea what the difference between Bak 4 and 7 is but does it make them better?????
