If portable, I would look at the garmin 176map C is the color model. Is
waterproof, submersible. Is what I am looking to replace my Garmin 45 with
for the ditch bag.

I'm in the market for a new GPS and would appreciate advice and
opinions from the group. I'm not sure what features are available and
which are important. I've done a fair amount of searching and have not
found a comprehensive listing of features for all units - only
listings by individual units. I'm more interested in knowing which
features the group finds necessary or convenient rather than
recommendations of individual units but would appreciate hearing about
favorites as well. I know I want a large screen as my eyes aren't what
they used to be - I know I want mapping - # of waypoints is
unimportant as most have thousands and I don't think I want to go to
that many places. I noticed a couple of smaller units are suitable for
auto use as well as marine and some give audible directions - this
could be handy in my travels if anyone makes a larger unit. Thanks for
your time - look forward to hearing from the group.
