You've brought up a good point actually. Typically, there are only 21-24 satelites operating at one time in the sky. At some point, there were actually 27. But the point of the 50 channel receiver vs. the 16 is that it allows you to grab a signal from as many as you can, that way if you move out of signal from one, you've already got or are working on a signal from another. Also, even though you only need 3 to triangulate a position (4 for altitude), having more gives you a little better accuracy. Now obviously, Humminbird went a little overboard with a 50, but from what I can figure, they've upgraded it so much that having this extra capacity allows for a much faster satelite aquisition rate, and have noticed a lot less complaints of signal loss out of the Humminbirds (internal and external alike) compared to any Lowrance (including external GPS modules).Originally Posted by MASBASS
One other perk of Humminbird I forgot to mention was the speed of their processors. The reason of why I doubt Lowrance's Structure Scan will compare is because it must work seemlessly with the GPS to locate and mark structure. Humminbird's processors blaze through information, including Navionics Charts, while I have actually froze up multiple Lowrance HDS units, some with the Lake Insight maps (less information than Navionics). This is a major factor that makes Side Imaging such an unbeatable piece of technology, once you get to the nity-grity of the unit. Feel free to come to Bass Pro in Clarksville to compare the HDS and Humminbirds side-by-side. And don't worry, we don't make commission, so bring any more questions you might have.Hope this helps!
