What is the best USB devise for a mac laptop?
thinking about using it as a backup

[Stu Jackson]

The Globalstar BU-353 should work, it seems the most popular one I've read about, so we bought one, but use it on a W7 platform. Check with Panbo: The Marine Electronics Hub for more details are Google BU353.

Best for every of us - different :-), depends from criterias

Simplest way - BU-353 USB
But for example if Your boar metal or very thick and no GPS inside - You can connect many external GPS antenna using NMEA to USB cables

Yes, bluetooth GPS also works
