I don't understand what you mean by this. The more channels you have available for your GPS, the better. Faster lock-on times, better accuracy, better coverage in difficult areas, etc...
Each 'channel' basically means the number of sattelites the GPS receiver could have access to simultaneously. Usually, the more channels you are capable of, the more expensive the receiver.
My understanding is that there would NEVER be an occasion (due to line of sight to the sats, and thus lower number in mountains) where you would see more than 12 sats at any one time, and even then it would be very rare to see 12 at a time. 16 channels is just like saying. "my stereo goes to 11"
Perhaps I'm wrong, and perhaps it has"Faster lock-on times, better accuracy, better coverage in difficult areas"
but unless you have some factual data to support this I will have to rely on what I've heard before.
accuracy is dependant on whether it has a properly implemented algorithm to determine position, 6 sats or 600 sats isn't going to make a difference with a poor calculation. if by difficult areas, you mean the bottom of the grand canyon, then sorry, once again if you've got 6000000000000000 channels, but still just have line of sight to 2 or 3, it's not going to make a difference.
Feel free to slam me on anything that I have not properly outlined (didn't really want to take the extra time to look up the stuff, just pulling this from what I think I remember as being correct, so if I'm wrong, shoot me or something)
btw, I could possibly see the use for more than 12 channels in something like a sail boat or something where you might see 12 sats at a given time, then during the transition period you see that 13th one coming on, so that you always have your 12 sats locked at any given time.
Maybe I'm jealous this gps has 16 chans, or maybe I'm content with my $25 12 chan (in parallel) reciever
have fun for those of you that got this.
