Why is the 5200c more expensive than the 520c when it is a GPS unit only? As far as I can see they have identical GPS specifications and wonder why someone would pay $100 more for a unit that can’t be used as a sonar if need be?
Am I missing something or does the 5200 come with the GPS antenna while the 520 does not for that price?
The other question is about said antenna. What is the difference between the 3000 and 2000 series?
Does the 520 come with any networking accesories? Cables, T’s, etc?
Thanks.
