    I would imagine that the market for Zone 5 compasses will dry up, where
    knowledgeable consumers are concerned. But that market was always small
    (more or less confined to Australians and New Zealanders) and a
    relatively high proportion of its members are world travellers. (I'm
    assuming that yachts passing through Zone 5 from elsewhere carry
    "global" compasses, as ships on the same routes certainly do.)
    In contrast, most of the people on this planet who are wealthy enough to
    care about a quality compass live in Zone 1 and never leave it -- or at
    least never undertake anything adventurous enough to need a compass
    outside their home zone. Thus, I suspect that the market for lower-cost,
    zone-specific compasses will remain. Which means that Zone 5 variants of
    those designs will continue to be peddled to unsuspecting Aussies.
