This is a tale of two GPS units: the Magellan MAP 330 and the Lowrance GlobalMap 100. This, however, is not a one-on-one comparison; that would be like comparing pineapples with coconuts (field test venue: Caribbean Sea).
The Magellan is a lightweight, shirt-pocket model, best suited for backup or dinghy use. The Lowrance is handheld, too, but with real heft. With optional bracket mount, it could well serve as the primary GPS for a small yacht.
