Bizer or others that may have a clue,
I know nothing about GPS other than using NeverLost when I travel, so please forgive my ignorance on the subject. I am looking for a transportable GPS primarily for my motorcycle and the car, but it would be nice to use on the lake occasionally as well. The Zumo 450 is sold as a bike GPS system that also works in the car, but says nothing of marine use. Is there any reason why it would not work with your Lake Winni data?
I've been navigating the lake OK for about 14 years without one so I'm thinking I don't need a lot of features. I would primarily use it to add a level of comfort if I occasionally needed to get from say from Wolfeborough or Gilford back to Moultonborough at night. Here is a link to the unit at Amazon.
