Lowrance GPS

Hello all,

I put away a few pennies here and there and now its time to invest in a
good GPS receiver. I've decided that the Lowrance will give me all I need.
And maybe more since I won't be doing any IFR. (Yes, I know it isn't IFR
rated anyway. The point is I won't need it for IFR backup, etc..)

Q1 -- Why should I buy the color system over the B&W?

Q2 -- Can either the 1000 or 2000c be loaded with the land database and used
to navigate on the ground?

Q3 -- Anybody ever time out a set of fresh alkaline batteries?
How long did they last?
Same question(s) for NiMH, please

Q4 -- Any druthers on a different brand?

Go Fly!
