I wouldn't mess around if you're talking about the Sac river delta. There
are a thousand miles of waterways in there, and it's easy to get lost if you
aren't familiar with it. A 3.5" screen is hard enough to see on dry land,
let alone in a moving boat. I used to use a handheld, then finally installed
a chart plotter/sounder and couldn't be happier. Yes, it costs a few $$
more, but in my humble opinion, well worth it. I have NO problem navigating
the delta with it, but still have trouble finding the fish with it g.
Plus, if you ever boat at night, there's nothing more re-assuring than a
nice BIG screen directing the way home.

My 2 cents.

Ok, so I call Garmin and here is what I need for the Nuvi 500 in order
to use it while boating the Delta, it's the:
US021R - California-Mexico - $160.70
So, $200 for the unit and $160 for the card = $360. Now I'm wondering
if it's worth it. A unit made specifically for marine application
will run over $600. But it does have a larger screen.
Any thoughts on this? Good, bad?

Thanks again
Eddie
